RE: [Condor-users] Condor on Windows

["Alan Christy Arokiam" <alanca@xxxxxxxxxxxxxxx>]

Dear Liu,
I run long term (up to 100s days) jobs on WinXP pro/Condor pool that is
available at off-peak time.

My code/program supports check pointing natively, so we use recursive DAG to
resubmit the jobs, obviously your code needs to be "aware" of the
environment, such as time, and kill itself safely when needed to initiate a
transfer back to the submit host, and using recursive DAG submit itself to
restart on a new run.

As per compiler, simply use a statically compiled binary or submit the
runtime libs/dlls as input!

I use the commercially available Intel FORTRAN compiler as we only buy Intel
CPUs, which generally gives about 50% - 60% performance benefit over the GNU
one. 
Hope it helps
