Simple mathematical operation in script section

[monicagiraldochica]

Hi, would it be possible to have two numerical widgets, say gpus and threads_per_gpu, and create a new variable that is the multiplication of both to use in script section? something like #SBATCH --cpus-per-task=#{gpus}*#{threads_per_gpu}. If that is possible, how can that be implemented?

Thanks!

Thank you for your inquiry.
Currently, there is no way to directly implement it.
The feature is very important, but difficult to implement, so it is pending.

However, there is currently an indirect way to implement this.
You can pass options to the job scheduler using the OC_SUBMIT_OPTIONS option within the submit section.
https://riken-rccs.github.io/OpenComposer/docs/application.html#submit

Therefore, you should be able to use it by configuring it as follows:

submit: |
  #!/bin/bash
  cpus_per_task=$((#{gpus}*#{threads_per_gpu}))
  OC_SUBMIT_OPTIONS="--cpus-per-task=${cpus_per_task} --export=NONE"

Thanks,

Sorry for the wait.
The main branch now supports simple calculations. Use the following syntax:

#SBATCH --cpus-per-task=#{calc(gpus * threads_per_gpu)}
For more details, please refer to: https://riken-rccs.github.io/OpenComposer/docs/application.html#functions

thanks it works!
