To request one or more GPUs for a Slurm job, use this form: --gpus-per-node= [type:]number. The square-bracket notation means that you must specify the number of GPUs, and you may optionally specify the GPU type. Choose a type from the "Available hardware" table below. Here are two examples: --gpus-per-node=2 --gpus-per-node=v100:1.

This means that if your job is shorter than 30 seconds, it will show that your calculation consumed zero memory which is probably wrong. The sampling rate also means that if your job contains short peaks of high memory consumption, the sampling may completely miss these. top solutions naples florida
