Intel introduced a number of new products, code name {{intel|Cascade Lake Advanced Performance|l=core}}, which doubled the core count. Intel achieved this by packaging two extreme core count (XCC) dies together on the same substrate in a BGA package. The two dies are interconnected through 1 {{intel|UPI}} link which paved the way for models up to 56 cores. This was done to support a fully-connected system in a 2-way SMP system which is where those chips are designed to go. In those systems, every die is interconnected to every other die (four in total) over a {{intel|UPI}} link. With to dies per package, each CPU exposes 12 DDR4 memory channels and x40 PCIe Gen3 lanes.

One of the other features that was added in Cascade Lake is Speed Select Technology (SST) which allows a chip to be configured in the field for various workloads such as throughput and single-core performance. This is done through configurations that allow the end user to determine how the power budget is spent. For example, single-thread performance can be further increased for fewer chips by further decreasing the base frequency of more inactive core. Alternatively, higher throughput can be achieved by increasing the base frequency of some cores while reducing the base frequency of other cores. All in all, the conigurations are ultimately bound by the power budget of the chip, however the custom tweaking of frquency (base, turbo, or otherwise) enable custom tuning of affinitized workloads.

== Persistent Memory Support ==
+
== Specialized SKUs ==
 +
Though Intel has been providing various customers with specialized SKUs for a long time, with Cascade Lake, Intel started doubling down on specialized SKUs. Many SKUs that were sought after by customers were introduced as mainstream SKUs in Intel's standard Xeon lineup. New SKUs can be grouped into the following categories:
 +
 
 +
* Speed Select Technology SKUs
 +
* Specialized for network function virtualization
 +
* Specialized for networking and IoT (NEBS Friendly)
 +
* Specialized Search Application
 +
* Extended Memory
 +
 
 +
=== Speed Select Technology (SST) ===
 +
{{main|intel/speed_select_technology|l1=Speed Select Technology (SST)}}
 +
Speed Select Technology is a new feature found on SST-enabled SKUs that allows for finer per-core power/performance configuration. SST-enabled SKUs come with additional controls that allow system administrators to change the turbo and base frequencies of certain cores. Those cores (called prioritized cores) can then have certain applications with higher priority affinitized to them. Since the power budget of the processor is fixed, with less prioritized cores, it’s possible to increase the base or turbo frequency. This can be furthered improved by reducing the frequencies of lower-priority cores (below their pre-defined base frequencies). In other words, SST allows for higher performance for priority workloads through the sacrifice of lower-priority workloads.
 +
 
 +
=== VM Density Value Specialized SKUs ===
 +
VM density value optimized are SKUs that have been optimized to provide higher ROI for customers that benefit more from the higher thread count. There are two new VM density SKUs. Those models are suffixed with a ‘V’.
 +
 
 +
=== Network Function Virtualization (NFV) SKUs ===
 +
NFV models are optimized for dynamic density VMs with additional headroom for higher subscribe capacity. NFV SKUs also feature speed select profiles with configurable priority based on the kind of workloads that are running. There are three new NFV SKUs. Those models are suffixed with a ‘N’.
 +
 
 +
=== Search Application Value specialized ===
 +
The search-optimized SKU is mainly designed for cloud search applications. Those models are designed such that they have predictable performance and latencies. There is one new search-optimized SKUs. Those models are suffixed with an ‘S’.
  
Intel Optane DC Persistent Memory (DCPMM) (Codename: Apache Pass) will be supported starting with Cascade Lake. The next architecture/codename is Barlow Pass.
+
=== Specialized for networking and IoT (NEBS Friendly) ===
 +
Models that are suffixed with “T” have extended lifetime (10 year use) guarantees and NEBS-friendly packing specification. There are four new NEBS-friendly SKUs.
  
DCPMM is designed to improve overall Data Center (DC) system performance and to lower latencies by putting more data closer to the processor on NV Media.
+
=== Extended Memory SKUs ===
 +
Beyond the normal supported memory, Intel also offers fourteen additional SKUs with extended memory support. Xeon Scalable models with the ‘M’ suffix offer medium DDR memory tier support with up to 2 TiB of memory per socket. Above those SKUs are ‘L’-suffixed SKUs which offer large memory support of up to 4.5 TiB of memory per socket.
  
DCPMM Modules are DDR4 socket compatible, and will be available in capacities up to 512GB/Module.  
+
== Persistent memory support ==
 +
{{see also|x86/persistent_memory_extensions|snia/npm|l1=Persistent Memory Extensions|l2=NVM Programming Model}}
 +
Cascade Lake introduces support for persistent memory. For Cascade Lake, this comes in the form of first-generation Optane DC Persistent Memory Modules (DCPMM), codename Apache Pass. PMMs are designed to improve the overall data center system performance by bringing a larger amount of data closer to the processor, in terms of latency, but behind DRAM.
  
=== DCPMM Modules Sizes ===
+
For first-generation Optane DC DIMMs, Intel supports capacities of 128, 256, and 512 GiB. The DIMMs are DDR4 pin-compatible and although they are slightly slower than DRAM, they are considerably faster than a typical SSD - fast enough to double up as "slow main memory". Optane DC DIMMs are designed to work with direct byte-addressable load/store accesses and have built-in encryption. They allow cache line access (i.e., 64B granularity) and offer idle latency close to that of DDR4 DIMMs.
  
* 128GB
+
[[File:cascade-presistence.png|right|thumb|Persistence domain]]
* 256GB
+
Although Optane DC DIMMs are DDR4 pin-compatible, meaning they use the same electrical and mechanical interface as DDR4, they are not a direct drop-in replacement. Those DIMMs have different characteristics and therefore they interface with the CPU over proprietary protocol extensions. For this reason, Cascade Lake features an overhauled memory controller capable of interfacing with both DDR4 DIMMs and Optane DC DIMMs. Memory channels can be shared between DDR4 and Optane DC modules. For example, a single channel can have one regular DDR4 DIMM while the other DIMM can be an Optane DC DIMM. All in all, Optane DC DIMMs allow for greater than 3 TiB of system memory per socket.
* 512GB
 
  
=== DCPMM Specs ===
+
Although the instructions to support persistent memory were already introduced in {{\\|Skylake (Server)|Skylake}}, Cascade Lake can now actually make use of them. The bare minimum for persistent memory support can be realized by simply putting the data in the write pending queue (WPQ) of the integrated memory controller within the persistence domain. The persistence domain is a unique checkpoint. Once data makes it to that point, it’s persistence is guaranteed by the platform interface. This is shown in the diagram on the right in the bottom dotted box. Any data within that box is either saved on the DIMM, on the way to the DIMM, or in the WPQ in the IMC. Regardless of where it is, the platform is required to store enough energy (e.g., through on-board supercapacitors) to save everything within that box in the event of a power loss.
  
* Capacity Per CPU: 3TB
+
=== Encryption ===
* Speed 2666MT/sec
+
[[File:cascade-lake-optane-dimm-encryption.png|right|thumb|PMM Encryption]]
* Close to DRAM latency
+
One of the unique problems associated with persistent memory is the security of the persistent data itself. To that end, Optane DIMMs protects all data with 256b AES-XTP. There are two supported modes. The first one is memory mode where the DIMM is treated like DRAM memory (one big cache) and as such, the key is regenerated each boot and data is lost on a power cycle. The second mode is App Direct which keeps the key on a power cycle. In this mode, the passphrase must be securely stored to unlock the data. Interestingly, one of the features that are currently missing is support for any form of virtualization. Currently, in a virtualized environment, the DIMM is unlocked using a single passphrase meaning the host has access to all the data. It’s reasonable to expect that in future Xeons, support for virtualization will be added such that data can be remained encrypted and private for that VM.

Overview[edit]

skylake server overview.svg

Cascade Lake is Intel's direct successor to the Skylake server microarchitecture. It is designed to be compatible with the Skylake parts (LGA-3647) and utilize the Purley platform. To that end, Cascade Lake shares the same socket and pinout as well as the same core count, cache size, and I/O capabilities.

Cascade Lake introduces initial in-hardware Spectre and Meltdown mitigation, including Variant 2, 3, and L1TF. Chips are fabricated on an enhanced 14 nm process which allows Intel to extract an additional power efficiency, allowing them to clock those processors higher. Intel noted that targeted performance improvements were applied to some of the critical paths to make this possible. Although the core architecture is largely identical to that of Skylake, Cascade Lake introduces support for AVX512VNNI which is designed to improve the performance of Artificial Intelligence workloads by improving the throughput of tight inner convolutional loop operations.

The chief modification to Cascade Lake is the overhauling of the integrated memory controller in order to introduce support for persistent memory. The IMC on Cascade Lake is capable of interfacing with both DDR4 DIMMs and Intel's Optane DC DIMMs. Memory channels can be shared between DDR4 and Optane DC modules. For example, a single channel can have one regular DDR4 DIMM while the other DIMM can be an Optane DC DIMM. All in all, Optane DC DIMMs allow for greater than 3 TiB of system memory per socket.

A superset model is shown on the right. Cascade Lake-based servers make use of Intel's mesh interconnect architecture. In this configuration, the cores, caches, and the memory controllers are organized in rows and columns - each with dedicated connections going through each of the rows and columns allowing for the shortest path between any tile, reducing latency, and improving the bandwidth. Those processors are offered from 4 cores up to 28 cores with 8 to 56 threads.

All models incorporate 6 channels of DDR4 supporting up to 12 DIMMS for a total of 1.5 TiB (with extended models support 3 TiB). For I/O all models incorporate 48x (3x16) lanes of PCIe 3.0. There is an additional x4 lanes PCIe 3.0 reserved exclusively for DMI for the the Lewisburg (LBG) chipset. For a selected number of models, specifically those with F suffix, they have an Omni-Path Host Fabric Interface (HFI) on-package (see Integrated Omni-Path).

Cascade Lake processors are designed for scalability, supporting 2-way, 4-way, and 8-way multiprocessing through Intel's Ultra Path Interconnect (UPI) interconnect links, with two to three links being offered (see § Scalability). High-end models have node controller support allowing for even higher way configuration (e.g., 32-way multiprocessing).

Core[edit]

Cascade Lake core is largely identical to that of Skylake's. For in-depth detail of the Skylake core/pipeline see Skylake (client) § Pipeline.

Execution engine[edit]

Scheduler Ports & Execution Units[edit]

cascade lake scheduler.svg

Although the core is largely identical to Skylake's, there are a few minor changes in Cascade Lake. In order to accommodate the new AVX512-VNNI instructions, new logic was added on Port 0 and Port 1. Where there was previously two FMA units for doing fused multiply-add floating-point operations, in Cascade Lake, new VNNI logic was added to that block which does a similar operation but works on integer data types. Support for 8-bit and 16-bit integers was added. It's worth noting that since integers dynamic range is quite low, the accumulation is performed on a 32-bit integer destination.


Higher core-count multi-chip processors[edit]

Overview slide
Cascade Lake AP
Cascade Lake AP board
Main article: Cascade Lake Advanced Performance

Intel introduced a number of new products, code name Cascade Lake Advanced Performance, which doubled the core count. Intel achieved this by packaging two extreme core count (XCC) dies together on the same substrate in a BGA package. The two dies are interconnected through 1 UPI link which paved the way for models up to 56 cores. This was done to support a fully-connected system in a 2-way SMP system which is where those chips are designed to go. In those systems, every die is interconnected to every other die (four in total) over a UPI link. With two dies per package, each CPU exposes 12 DDR4 memory channels and x40 PCIe Gen3 lanes.

Package[edit]

Cascade Lake AP uses a high-density high-performance ball grid array (BGA) package. It has 5,903 balls at a 0.99 mm pitch. There are two separate power corridors for performance and power reasons. It uses a single heat spreader designed to cover the entire TDP range for all processor models. In total, each package exposes 12 channel DDR4 supporting rates of up to 2933 MT/s as well as 4 UPI links operating at 10.4 GT/s.

CPUID level type[edit]

Because there are multiple dies in the same package for Cascade Lake AP processors, software that wanted to take this into consideration for better optimization can do so through a new level type CPUID value for 5 = die.

New Technologies[edit]

AVX-512 Vector Neural Network Instructions[edit]

Main article: AVX-512 Vector Neural Network Instructions

Cascade Lake added support for AVX-512 Vector Neural Network Instructions (AVX512 VNNI). This extension introduces new instructions for accelerating inner convolutional neural network loops. Operations on both 8-bits and 16-bit pairs are supported. The new extension reduces the memory bandwidth required to perform a scalar-pair multiply followed by the summation of horizontal pairs and accumulate. For 16-bit operations, two common operations were fused into a single instruction while for 8-bit operations, the three common operations were fused into one.

Speed Select Technology[edit]

Main article: Speed Select Technology

One of the other features that was added in Cascade Lake is Speed Select Technology (SST) which allows a chip to be configured in the field for various workloads such as throughput and single-core performance. This is done through configurations that allow the end user to determine how the power budget is spent. For example, single-thread performance can be further increased for fewer chips by further decreasing the base frequency of more inactive core. Alternatively, higher throughput can be achieved by increasing the base frequency of some cores while reducing the base frequency of other cores. All in all, the conigurations are ultimately bound by the power budget of the chip, however the custom tweaking of frquency (base, turbo, or otherwise) enable custom tuning of affinitized workloads.

Specialized SKUs[edit]

Though Intel has been providing various customers with specialized SKUs for a long time, with Cascade Lake, Intel started doubling down on specialized SKUs. Many SKUs that were sought after by customers were introduced as mainstream SKUs in Intel's standard Xeon lineup. New SKUs can be grouped into the following categories:

  • Speed Select Technology SKUs
  • Specialized for network function virtualization
  • Specialized for networking and IoT (NEBS Friendly)
  • Specialized Search Application
  • Extended Memory

Speed Select Technology (SST)[edit]

Main article: Speed Select Technology (SST)

Speed Select Technology is a new feature found on SST-enabled SKUs that allows for finer per-core power/performance configuration. SST-enabled SKUs come with additional controls that allow system administrators to change the turbo and base frequencies of certain cores. Those cores (called prioritized cores) can then have certain applications with higher priority affinitized to them. Since the power budget of the processor is fixed, with less prioritized cores, it’s possible to increase the base or turbo frequency. This can be furthered improved by reducing the frequencies of lower-priority cores (below their pre-defined base frequencies). In other words, SST allows for higher performance for priority workloads through the sacrifice of lower-priority workloads.

VM Density Value Specialized SKUs[edit]

VM density value optimized are SKUs that have been optimized to provide higher ROI for customers that benefit more from the higher thread count. There are two new VM density SKUs. Those models are suffixed with a ‘V’.

Network Function Virtualization (NFV) SKUs[edit]

NFV models are optimized for dynamic density VMs with additional headroom for higher subscribe capacity. NFV SKUs also feature speed select profiles with configurable priority based on the kind of workloads that are running. There are three new NFV SKUs. Those models are suffixed with a ‘N’.

Search Application Value specialized[edit]

The search-optimized SKU is mainly designed for cloud search applications. Those models are designed such that they have predictable performance and latencies. There is one new search-optimized SKUs. Those models are suffixed with an ‘S’.

Specialized for networking and IoT (NEBS Friendly)[edit]

Models that are suffixed with “T” have extended lifetime (10 year use) guarantees and NEBS-friendly packing specification. There are four new NEBS-friendly SKUs.

Extended Memory SKUs[edit]

Beyond the normal supported memory, Intel also offers fourteen additional SKUs with extended memory support. Xeon Scalable models with the ‘M’ suffix offer medium DDR memory tier support with up to 2 TiB of memory per socket. Above those SKUs are ‘L’-suffixed SKUs which offer large memory support of up to 4.5 TiB of memory per socket.

Persistent memory support[edit]

See also: Persistent Memory Extensions and NVM Programming Model

Cascade Lake introduces support for persistent memory. For Cascade Lake, this comes in the form of first-generation Optane DC Persistent Memory Modules (DCPMM), codename Apache Pass. PMMs are designed to improve the overall data center system performance by bringing a larger amount of data closer to the processor, in terms of latency, but behind DRAM.

For first-generation Optane DC DIMMs, Intel supports capacities of 128, 256, and 512 GiB. The DIMMs are DDR4 pin-compatible and although they are slightly slower than DRAM, they are considerably faster than a typical SSD - fast enough to double up as "slow main memory". Optane DC DIMMs are designed to work with direct byte-addressable load/store accesses and have built-in encryption. They allow cache line access (i.e., 64B granularity) and offer idle latency close to that of DDR4 DIMMs.

Persistence domain

Although Optane DC DIMMs are DDR4 pin-compatible, meaning they use the same electrical and mechanical interface as DDR4, they are not a direct drop-in replacement. Those DIMMs have different characteristics and therefore they interface with the CPU over proprietary protocol extensions. For this reason, Cascade Lake features an overhauled memory controller capable of interfacing with both DDR4 DIMMs and Optane DC DIMMs. Memory channels can be shared between DDR4 and Optane DC modules. For example, a single channel can have one regular DDR4 DIMM while the other DIMM can be an Optane DC DIMM. All in all, Optane DC DIMMs allow for greater than 3 TiB of system memory per socket.

Although the instructions to support persistent memory were already introduced in Skylake, Cascade Lake can now actually make use of them. The bare minimum for persistent memory support can be realized by simply putting the data in the write pending queue (WPQ) of the integrated memory controller within the persistence domain. The persistence domain is a unique checkpoint. Once data makes it to that point, it’s persistence is guaranteed by the platform interface. This is shown in the diagram on the right in the bottom dotted box. Any data within that box is either saved on the DIMM, on the way to the DIMM, or in the WPQ in the IMC. Regardless of where it is, the platform is required to store enough energy (e.g., through on-board supercapacitors) to save everything within that box in the event of a power loss.

Encryption[edit]

PMM Encryption

One of the unique problems associated with persistent memory is the security of the persistent data itself. To that end, Optane DIMMs protects all data with 256b AES-XTP. There are two supported modes. The first one is memory mode where the DIMM is treated like DRAM memory (one big cache) and as such, the key is regenerated each boot and data is lost on a power cycle. The second mode is App Direct which keeps the key on a power cycle. In this mode, the passphrase must be securely stored to unlock the data. Interestingly, one of the features that are currently missing is support for any form of virtualization. Currently, in a virtualized environment, the DIMM is unlocked using a single passphrase meaning the host has access to all the data. It’s reasonable to expect that in future Xeons, support for virtualization will be added such that data can be remained encrypted and private for that VM.

Scalability[edit]

See also: Ultra Path Interconnect

Cascade Lake continues to use Ultra Path Interconnect (UPI) which was first introduced with Skylake. UPI is a high-efficiency coherent interconnect for scalable systems, allowing multiple processors to share a single shared address space. Depending on the exact model, each processor can have either two or three UPI links connecting to the other processors.

Depending on the exact model, Cascade Lake processors can scale from 2-way all the way up to 8-way multiprocessing. Note that the high-end models that support 8-way multiprocessing also only come with three UPI links for this purpose while the lower end processors can have either two or three UPI links. Below are the typical configurations for those processors.


2-way SMP; 2 UPI links
