Introduction
In this tutorial we learn how to install htcondor
on Ubuntu 20.04.
What is htcondor
htcondor is:
Like other full-featured batch systems, HTCondor provides a job queueing
mechanism, scheduling policy, priority scheme, resource monitoring, and
resource management. Users submit their serial or parallel jobs to HTCondor;
HTCondor places them into a queue. It chooses when and where to run the jobs
based upon a policy, carefully monitors their progress, and ultimately
informs the user upon completion.
Unlike more traditional batch queueing systems, HTCondor can also effectively
harness wasted CPU power from otherwise idle desktop workstations. HTCondor
does not require a shared file system across machines – if no shared file
system is available, HTCondor can transfer the job’s data files on behalf of
the user.
This package can set up an appropriate initial configuration at install
time for a machine intended either as a member of an existing HTCondor pool
or as a “Personal” (single machine) HTCondor pool.
