Obtaining the Job Results

The run log for a running or completed job, or the job results for a completed job, can be obtained.

Obtaining the Run Log for a Mosel or a Solver job

The job details returned for a job with any status other than QUEUED will include a value for the runLogUrl property. This URL can be requested to retrieve the current run log content.

Obtaining the Results Zip for a Mosel job

The job details returned for a job with status of COMPLETED will include a value for the resultUrl property. Any files written to the results directory by your Mosel job will be picked up automatically and added to a zip file that incorporates the compute job id in the file name using the format [compute job id]-results.zip. The resultsUrl on the compute job response will then point to this zip.

Note Your submitted Mosel job should create a directory named results and publish any result files you wish to retrieve to this directory.

Obtaining the Results Zip for a Solver job

The job details returned for a job with status of COMPLETED will include a value for the resultUrl property. This URL can be requested to retrieve a zip of the result files. The name of the results zip file includes the job id in the format [compute job id]-results.zip to help identify it after download.

The results zip for a job of type SOLVER will always include a file solution-status.json which contains a map of the name of the problem LP/MPS/SVF file to the solver status.

Example solution-status.json file 
{
  "problemName": "Optimal"
}
The possible solver status values are:
  • Optimal
  • No solution found
  • Solution available
  • Infeasible
  • Unbounded
  • Unfinished
  • Unsolved
The other files contained with the results zip will be dependent on what was requested in the original job submission with the includeInResults property. For a problem filename MyProblem.mps:
  • SOLUTION: Results zip will include a solution file MyProblem.slx containing the last solution.
  • BASIS: Results zip will include a basis file MyProblem.bas containing the basis for the last LP solve.
  • ATTRIBUTES: Results zip will include a file [problem name]-attributes.json which contains a JSON object referencing an array of solver attributes and their values at the end of the solving process.
    Example [problem name]-attributes.json file 
    { 
  "att1Name" : {
    "key": 1234,
    "name": "att1Name"
    "value": "value"	
    }...
}
  • SAVE: Results zip will include a save file MyProblem.svf created by called XPRSsave at the end of the solving.
  • IIS: Results zip will include the output of the IIS action as a file MyProblem.lp.
