WN nodes¶

There are 2 IBM AC922 8335-GTG POWER9 nodes on Apocrita which are equipped with 4 Nvidia Tesla V100 16GB GPUs. These compute nodes use a ppc64le processor which is different from the more common x86_64, this means code needs to be recompiled on the Power nodes.

WN
Count	2
Processor	2 x 20 Core Power9 Witherspoon
GPU cores	20480 CUDA cores over 4 GPUs
Cores/Node	40
Threads/Node	160
RAM	314GB
TMP Size	839GB

Accessing the WN nodes¶

Access is permitted to QMUL researchers upon request. Please raise a support ticket by emailing its-research-support@qmul.ac.uk with a brief overview of intended use, so that we can verify that the jobs will run correctly on the POWER9 architecture.
