In the month of February, we added several compute nodes to the Phoenix cluster. This will give the Phoenix users the opportunity to use more powerful nodes for their computations, and to decrease the waiting time for high-demand hardware.
There are three groups of new nodes:
- 40 32-core Intel-CPU high-memory nodes (768 GB of RAM per node). These nodes are part of our “cpu-large” partition, and this addition increases the number of “cpu-large” nodes from 68 to 108. The nodes have Dual Intel Xeon Gold 6226R processors @ 2.9 GHz (with 32 instead of 24 cores per node). Any jobs that require more than 16 GB of memory per CPU will end up on the nodes from the “cpu-large” partition.
- 4 128-core AMD CPU nodes with 128 cores per node. These nodes are part of our “cpu-amd” partition, and this addition increases the number of “cpu-amd” nodes from 4 to 8. The cores are Dual AMD Epyc 7713 processors @ 2.0 GHz (128 cores per node) with 512 GB of memory. For comparison, most of the older Phoenix compute nodes have 24 cores per node (and have Intel processors rather than AMD). To target these nodes specifically, you can specify the flag “-C amd” in your sbatch script or salloc command:https://docs.pace.gatech.edu/phoenix_cluster/slurm_guide_phnx/#amd-cpu-jobs
- 7 64-core AMD CPU nodes with Nvidia A100 GPUs (two GPUs per node) with 40 GB of GPU memory. These nodes are part of our “gpu-a100” partition, and this addition increases the number of “gpu-a100” nodes from 5 to 12. These nodes have Dual AMD Epyc 7513 processors @ 2.6 GHz (64 cores per node) with 512 GB of RAM. To target these nodes, you can specify the flag “–gres=gpu:A100:1” (to get one GPU per node) or “–gres=gpu:A100:2” (to get both GPUs for each requested node) in your sbatch script or salloc command:https://docs.pace.gatech.edu/phoenix_cluster/slurm_guide_phnx/#gpu-jobs
