[slurm-users] API - Specify GPUs

[jpuerto--- via slurm-users]

Good Afternoon All,

It does not seem that the REST API allows for folks to configure their jobs to 
utilize GPUs, using the traditional methods. IE, there does not appear to be an 
equivalent between the --gpus (or --gres) flag on sbatch/srun and the REST 
API's job submission endpoint. Can anyone point me towards what should be used 
if the version we are on does not support tres specifications?

Best regards,

Juan Puerto

[slurm-users] REST API - get_user_environment

[jpuerto--- via slurm-users]

In previous versions (v0.0.36) of the REST API the job submission endpoint had 
a field titled "get_user_environment"; however, it doesn't appear to exist in 
v0.0.40. Is there an equivalent parameter that should be used? What is the 
suggested approach for mimicking this behavior in v0.0.40?

Best regards,

Juan

Ole,

I am referring to the REST API. We have had it installed for a few years and 
have recently upgraded it so that we can use v0.0.40. But this most recent 
version is missing the "get_user_environment" field which existed in previous 
versions.

Best,

Juan

Chris,

Any ideas on whether there's a way to mirror this functionality in v0.0.40?

Chris,

Do you have a link to that code? Haven't had any luck finding that repo

For those that are interested, I was able to resolve this by doing the 
following:

- Remove the "get_user_environment" attribute from the "jobs" attribute.
- Add an additional attribute to the "environment" attribute titled 
"SLURM_GET_USER_ENV" and setting that equal to 1.

Example before change:

{
 "job": {
  "get_user_environment": 1
 }
}

Example after change:
{
 "job": {
  "environment": {
   "SLURM_GET_USER_ENV": 1
  }
 }
}

Is anyone in contact with the development team? I feel that this is pretty 
basic functionality that was removed from the REST API without warning. 
Considering that this was a "patch" release (based on traditional semantic 
versioning guidelines), this type of modification shouldn't have happened and 
makes me worry about upgrading in the future.

Best regards,

Juan
