Here's another bit that could be clearer in the spec. We don't actually specify what happens on drmaa_synchronize() if the jobs don't exist. In the SGE implementation, we return immediately, as though the jobs are all finished. The drmaa_wait() call only implies that it should fail if the job doesn't exist. Both routine descriptions should have a very clear statement describing the behavior when the specified job(s) doesn't exist. We also should determine what the behavior for drmaa_synchronize() should be. I vote for the same as for drmaa_wait(), i.e. waiting for a list of jobs that contains invalid (or already waited for) job ids will fail. The exception would be waiting for all jobs, but we've already had that conversation.

I'm launching many jobs with qsub, and then later collecting the corresponding job ids and passing those to drmaa_synchronise(). Although drmaa_synchronise() returns without error, it returns before the jobs are complete. Am I to assume that drmaa_synchronise() only works with jobs launched with drmaa_run_job()? == Code Sample (PERL) == # for writing to qsub use IPC::Open2; # for timing use Time::HiRes; use Schedule::DRMAAc qw/ :all /; my $job = "md5sum /etc/fstab"; @alljobs = (); ( $error, $diagnosis ) = drmaa_init( undef ); die drmaa_strerror( $error ) .
