Extra Ampere GPUs in Hydra#
We are happy to announce the immediate availability of 2 more GPU nodes in
Hydra adding 4 new Nvidia A100 GPUs to the cluster. These new nodes are
ampere_gpu partition and share the same CPU, memory and GPU
configuration with the other nodes in this partition.
2x Nvidia A100 GPU (40 GB of GPU memory)
2x AMD Epyc 7282 CPUs (16 CPU cores)
256 GB CPU memory
EDR (100Gbit) InfiniBand network
25 Gbit Ethernet network
The total capacity of the
ampere_gpu partition at the time of this writing
is 18x Nvidia A100.
These 2 nodes have a very fast local scratch storage made of SSD drives with a total capacity of 5.9 TB. This fast SSD storage will increase the performance of jobs that access big databases intensively with random patterns, such as AlphaFold.
Only 4 of the nodes in
ampere_gpu have this fast storage though. You can
submit your jobs specifically to this type of nodes by using the
--constraint="big_local_ssd". The fast local scratch in these nodes is
accessible as usual, through the environment variables
$TMPDIR. In the future we will provide an option to automatically transfer
large databases to the fast local scratch of these new nodes.
A wide range of software is already available on these nodes (
avail), but if you need anything else, please let us know at VUB-HPC Support.
