Under systems, like PBS, TORQUE, LSF, etc. When a job is submitted and goes into the "Running" state the Workload Manager sets an environment variable such as PBS_NODEFILE or LSB_MCPU_HOSTS, which contains the names of the nodes that have been allocated for the job. Is there a MS Job Scheduler equivalent? Basically, I've created an application that uses the command-line to create a job and then submit it. I use a jobfile as a "template" and then modify the template based on a users input. The problem is that my application starts a client application that then invokes a call to mpiexec. [NOTE: Here template refers to my application template, note the job scheduler template used to define job policy.] My goal is to make sure that the mpiexec uses the resources allocated for the job. The basic pattern looks as follows:
query user for job details
generate XML job file from a generic xml job file.
create new job:
job new /jobfile:[my_jobfile.xml]
submit job:
job submit /id:[my_job_id]
The CommandLine attribute in the Task element of of my job file starts a an application, which in turn starts an MPI application via mpiexec.
I would like to be able to make sure mpiexec uses the resources allocated to the job.
I know that this is somewhat convoluted, but one of my goals is to create a framework that is generic as possible and allows me ot run under multiple platforms and multiple workload managers. My current abstraction gives me that flexibility so I am hesitant to move to a new implementation unless I can be convinced that it is really the right thing to do.
Thanks for any suggestions.
