Re: [HTCondor-users] maximum of 9 dynamically allocated slots on Windows?

Thanks Todd for the quick response and workable solutions.

Idea #2 looks like a winner for us. I forgot to mention that our Windows boxes are running Win7 x64 Enterprise and Condor 8.0.6.

Poring over logs reveals that jobs are trying to start on slots 10

like the user used to run these jobs ( condor-reuse-slot1_XX ) cannot
be created, thus resulting in permission errors. Windows usernames
appear to have a limit of 20chars, which looks like it's causing the
21-character condor username to fail ( condor-reuse-slot1_X is OK but
condor-reuse-slot1_XX is not ).


The current workaround we've employed is creating 4 partitionable
slots, each with 25% share of resources. Of course this means that
the maximum amount of ram etc. that any single job can use is more
limited than it would be using a single partitionable slot. Note,
this is not a problem on our linux machines.


Is this a known bug? Is there a better solution/workaroundi


Hi Alex -

Thanks for the diagnosing the problem so completely and taking the time to bring it to our attention.  We will fix this issue for v8.2.0.

I created a ticket about this problem on the wiki here:
 https://htcondor-wiki.cs.wisc.edu/index.cgi/tktview?tn=4388

At the above URL, I described how we will fix the issue for the next release of HTCondor (v8.2.0), and also brain-stormed some potential workarounds that you may like better.

Hope the above helps,
regards,
Todd
