Enclose the shell command line in double quote marks, so it may be passed to condor_run without modification. condor_run will not read input from the terminal while the job executes. If the shell command line requires input, redirect the input from a file, as illustrated by the example
% condor_run "myprog < input.data"
condor_run jobs rely on a shared file system for access to any necessary input files. The current working directory of the job must be accessible to the machine within the HTCondor pool where the job runs.
Specialized environment variables may be used to specify requirements for the machine where the job may run.
When one or more of these environment variables is specified, the job is submitted with:
Requirements = $CONDOR_REQUIREMENTS && Arch == $CONDOR_ARCH && \ OpSys == $CONDOR_OPSYS
Without these environment variables, the job receives the default requirements expression, which requests a machine of the same platform as the machine on which condor_run is executed.
All environment variables set when condor_run is executed will be included in the environment of the HTCondor job.
condor_run removes the HTCondor job from the queue and deletes its temporary files, if condor_run is killed before the HTCondor job completes.
condor_run may be used to compile an executable on a different platform. As an example, first set the environment variables for the required platform:
% setenv CONDOR_ARCH "SUN4u" % setenv CONDOR_OPSYS "SOLARIS28"
Then, use condor_run to submit the compilation as in the following three examples.
% condor_run "f77 -O -o myprog myprog.f"or
% condor_run "make"or
% condor_run "condor_compile cc -o myprog.condor myprog.c"
condor_run creates the following temporary files in the user's working directory. The placeholder <pid> is replaced by the process id of condor_run.
condor_run is intended for submitting simple shell command lines to HTCondor. It does not provide the full functionality of condor_submit. Therefore, some condor_submit errors and system failures may not be handled correctly.
All processes specified within the single shell command line will be executed on the single machine matched with the job. HTCondor will not distribute multiple processes of a command line pipe across multiple machines.
condor_run will use the shell specified in the SHELL environment variable, if one exists. Otherwise, it will use /bin/sh to execute the shell command-line.
By default, condor_run expects Perl to be installed in /usr/bin/perl. If Perl is installed in another path, ask the Condor administrator to edit the path in the condor_run script, or explicitly call Perl from the command line:
% perl path-to-condor/bin/condor_run "shell-cmd"
condor_run exits with a status value of 0 (zero) upon complete success. The exit status of condor_run will be non-zero upon failure. The exit status in the case of a single error due to a system call will be the error number (errno) of the failed call.
