There exist various administrative scripts which run on the cluster automatically. If you find that your job has been held, designated by 'H' as a status, please use the following guidelines to understand why.
There exist various administrative scripts which run on the cluster automatically. One such script will examine running jobs and hold them if they are meet certain conditions. If you find that your job has been held, designated by 'H' as a status, please use the following guidelines to understand why.

=== Over Maximum Run Count ===
=== Over Maximum Run Count ===
The ClassAd <i>HoldReason</i> states
<pre>
<user> job <jobid> removed because its RunCount # > 99
</pre>
This means that your job has started # times which is more than the maximum allowed restarts. Typically, this indicates a problem with the job and should be removed. The code should be examined to find why it continually fails.
=== Used More Memory Than Requested ===
=== Used More Memory Than Requested ===
=== Used More Memory Than Slot Provided ===
The ClassAd <i>HoldReason</i> states
<pre>
<user> job <jobid> removed because its MemoryUsage # > 1200 and # > <RequestedMemory> * 1.2
</pre>
This means that your job used more memory than the default minimum memory as well as exceeded the requested memory scaled by a factor of 1.2. If a user does not explicitly request memory, this is calculated by a formula in Condor.
The user should either
# Request memory slightly larger than the used memory OR
# Alter the code to produce a smaller memory footprint. This might involve breaking the code into smaller steps
=== Used More Memory Than Slot Memory Allocation ===
The ClassAd <i>HoldReason</i> states
<pre>
<user> job <jobid> put on hold because its MemoryUsage # > <SlotMemory> * 1.2 + 500 (by user condor)
</pre>
This means that your job used more memory than the default minimum memory as well as exceeded the allocated slot memory scaled by a factor of 1.2 + 500.
The user should either
# Request memory slightly larger than the used memory OR
# Alter the code to produce a smaller memory footprint. This might involve breaking the code into smaller steps
=== Used More Disk Than Requested ===
=== Used More Disk Than Requested ===
The ClassAd <i>HoldReason</i> states
<pre>
<user> job <jobid> removed because its RequestDisk # > 12000000 and # > <RequestedDisk> * 1.2
</pre>
This means that your job used more disk than the default minimum disk space as well as exceeded the requested disk scaled by a factor of 1.2. If a user does not explicitly request disk, this is calculated by a formula in Condor.
The user should either
# Request disk slightly larger than the used disk OR
# Alter the code to use less disk space.
