The AG cluster is based on the Eviden BullSequana XH3000 architecture, and consists of 30 accelerated compute nodes each configured with four Grace Hopper GH200 Superchips.
- Each node has 4 Grace Hopper superchips, a total of 480 GB of RAM and 384 GB of HBM3. Note that the GPU memory is also seen as main memory, so you will see a total of ~864 GB of RAM.
- Each grace chip has 72 ARM cores, 120GB of RAM and 96 GB HBM3 as GPU memory.
- Each node also has a local NVME of 3.5 TB mounted, accessible through $TMPDIR.
