We have received four GPUs for evaluation:
- 2 nVidia GeForce RTX 2080 and
- 2 nVidia GeForce RTX 2080 Ti
All four GPUs are installed in a single node with two Intel Xeon Gold 6140 CPUs (2.3 GHz) and 256 GiB of RAM.
Initially only jobs with a runtime up to 24 hours can use these nodes.
Any RTX GPU
Use the -R rtx bsub option to request either of these GPUs:
bsub -R rtx ./my_gpu_program
Specific RTX GPU
Due to limitations of the batch system you can not request a specific one of these GPUs. Instead you need to request all four GPUs
bsub -R rtx -R "rusage[ngpus_excl_p=4]" ./my_gpu_program
and then programatically select the desired GPU using CUDA. The first two GPUs are 2080 Tis while the last two are the 2080 non-Tis. For example to use only two 2080 Tis, run:
bsub -R rtx -R "rusage[ngpus_excl_p=4]" "CUDA_VISIBLE_DEVICES=2,3 ./my_gpu_program"
