[Condor-users] Why do remote job submissions on Linux require 'should_transfer_files'

[Thomas Luff <Thomas.Luff@xxxxxxx>]

I'm currently toying with remote job submission for our validation cluster and have come across a bit of an issue.

Jobs that are remotely submit to be run on Linux without specifying 'should_transfer_files = true' get stuck in the hold state with the following error:

    023.000:  Request is held.
    Hold reason: Error from slot1@xxxxxxxxxx: Failed to execute '/bin/sleep' with arguments 1m: Cannot access specified iwd "/work/condor/local/spool/23/0/cluster23.proc0.subproc0" (errno=2: 'No such file or directory')

The Linux job only gets stuck when remotely submitted (condor_submit -remote). It executes successfully when submitted locally.

A similar job can be run fine on a windows node with 'should_transfer_files = IF_NEEDED'.

My Jobs are as follows:
    Linux:
<pre>
        Executable = /bin/sleep
        Arguments = "1m"

        Requirements = (ARCH=="INTEL" || ARCH=="X86_64") && OpSys=="LINUX"

        transfer_executable = false
        should_transfer_files = TRUE
        WhenToTransferOutput = ON_EXIT
        Run_As_Owner = True
        Queue
</pre>

    Windows:
<pre>
         Executable = \\network\path\to\bin\perl
         Arguments = "-e '$time = time+60; sleep 1 until time > $time'" #Sleep 60 seconds

         Requirements = ((ARCH=="INTEL" || ARCH=="X86_64") && OpSys=="WINNT51")

         transfer_executable = false
         should_transfer_files = IF_NEEDED
         WhenToTransferOutput = ON_EXIT

         Run_As_Owner = True

         Queue
</pre>

My question is, Why is this needed and why is it different between Windows and Linux?

Thanks

P.S Has anyone successfully built Condor for ARM Linux?
