Running the application

The following lines are the contents of a simple generic HTCondor submit text file for a julia job.

Universe = vanilla

Requirements = (Target.Opsys == "LINUX" && Target.Arch == "X86_64" && <HTCondor ClassAd>=?=True)
Request_Memory = 1000

Log = julia.log
Output = julia.out
Error = julia.error
Notification = Error

Should_Transfer_Files = Yes
When_To_Transfer_Output = ON_EXIT

Executable = /usr/bin/julia
Transfer_Executable = False
Environment = HOME=/tmp
Arguments = <script>.jl <input_arguments>
Transfer_Input_Files = <script>.jl


If your submit file is called submit.txt then your job can be submitted to HTCondor using the command condor_submit submit.txt.
