Succession

ARCHER (Advanced Research Computing High End Resource) is HECToR's successor, a petascale x86 supercomputer serving as the UK's primary academic research supercomputer. ARCHER begun operations in March 2014 becoming the most powerful system in UK and the 19th most powerful on the TOP500 at the time. ARCHER is expected to be succeeded by ARCHER 2 in 2020.

Overview[edit]

ARCHER is based on Cray's XC30 MPP supercomputer.

System[edit]

Nodes4920
CPUXeon E5-2697 v2 (12c) @ 2.7 GHz
Cores118,080
Peak Performance2.551 petaFLOPS (DP)

Memory[edit]

There are 4544 standard memory nodes which have 64 GiB of memory shared between the two CPUs. Additionally, ARCHER features 376 high memory nodes which have 128 GiB of memory.

Count 4544 376 4920
Total 47 TiB 284 TiB 331 TiB


Interconnect[edit]

ARCHER relies on Cray Aries interconnect to interlink all the nodes. ARCHER uses a Dragonfly topology. There are four compute nodes connected per each Aries router, 188 nodes per cabinet, and two cabinets form a group. Groups are connected to each other with all-to-all optical connections. There are a total of 144 optical links per group for a peak system bisection bandwidth of over 19,013 GB/s. The MPI latency on Aries is ~1.3μs with an additional 100ns of latency when communicating over the optical links.
