I am not sure whether or not this was clarified in today's DRMAA conference. I vote for a tracker item, since the spec should clearly formulate that both options (error during submission vs. failed state of the job) are possible for an invalid job template.

We are in the gray area I would say.

A test code could reflect that.

DRMAA state diagram has a valuator stage that could reject a job like it happened here for Condor.

Sometimes these discrepancies happen due to quality of DRMAA implementation, sometimes due to DRM architecture. This is inevitable and we have agreed to have some latitude in the spec to reflect the realities in the marketplace.

Hi,

the SGE DRMAA test suite has a set of three tests for checking the behavior in case of incorrect job template settings for the input, output, or error file path. The following text is the description of the test case:

/* - drmaa_init() is called - a job is submitted with input/output/error path specification that must cause the job to fail - use drmaa_synchronize() to ensure job was started - drmaa_job_ps() must return DRMAA_PS_FAILED - drmaa_wait() must report drmaa_wifaborted() -> true - then drmaa_exit() is called */

The funny thing is that the test case expects the (wrong) template to be accepted by drmaa_run_job(), and then expects that the job status changes to FAILED.

This is due to sentences such as

"If set, and the file can't be read, the job enters the state DRMAA_PS_FAILED. The attribute name is drmaa_input_path."

in DRMAA spec.

...

The Condor implementation rejects the job template at submission time with DRMAA_ERRNO_DENIED_BY_DRM, which is in my opinion the right approach according to the spec.

Possibly with the Condor implementation a "drmaa_transfer_files"

setting

...

"ioe" is in effect by default. This would imply these files are located at the submit machine. At least this would be an explaination how

Condor

...

can detect at submit time these pathes are invalid.

In case of Grid Engine "DRMAA_PS_FAILED" is returned as the

defectiveness

...

of these pathes at the execution machine can't be determined before the try to start the job.
