Re: [HTCondor-users] Can I install Condor Central Manager on a virtual windows computer?

Hi Andrew,

Yes you could install Condor on a Virtual
Machine running Windows. We do so in our corporate pool. CM is a VM running
Linux, CREDD is also a VM with Windows. And we have some Executers also
as VM and running Windows. All other desktops are Windows machines (XP
or Win7).
For scheduling purpose on Windows Machines
you need to play with the MAX_JOBS_RUNNING (default is 200) to increase
the number of condor_shadow.exe processes Condor is allowed to start on
the scheduler machine. As you have a good amount of memory available, you
need to reserve some memory for the condor_collector.exe and condor_negotiator.exe
and remainder memory to use for condor_shadow.exe processes (about 5Mb
per process in newer versions of Condor, let say 8.0.x).
About performance, you need to monitor
your VM server to see its limits.

Hope this helps.

Klaus

I have a trial pool for Win7 x64 computers, and my
IT has given me a virtual Win7 x64 computer to play with. Is there any
reason why I cannot install HTCondor and run it as the Central Manager
for negotiations and scheduling? It reports that it is a 2.53GHz dual core
Xeon with 128GB RAM (!?). It has an IP address and everything else that
I would expect. I have been told that it may not be fast, but then my pool
is quite small at present.

Any thoughts? Any special settings?

Andrew
