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.

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.
