Enable option for hardcoding GPU memory request like its available for CPU memory request

At this moment IBM offers features of hardcoding CPU memory. We have implemented this feature in our cluster with esub scripting. Similarly we want to have same feature available for GPU memmory (gmem) to be hardcoded. I have raised ticket to our support portal and got reply its not available.

Please plan to implement this feature in LSF. This is one of the main drawback of LSF at this moment and and our users are in high need of it

    We have discussed this matter with NVIDIA and there is no mechanism currently in their API to enforce gpu memory usage. Their recommendation is that if you need to use less memory than the card provides, then using a card that supports MIG, and subdividing the GPU is the way to go.

    As there is no underlying way to implement this, we cannot progress this request.

    We can revisit it in the future, as and when the NVIDIA API provides a way to do it.

    Yes, we want a bsub -Mg (max gmem) or bsub -gpu "memlimit:xxxG" like option that will prevent user's GPU processes from exceeding their request.
