Just brainstorming, here are some ideas as to why it might be faster:
- The machines in your Condor pool might simply have faster
than your desktop machine. Trying logging directly into one and running your job.
Tried that... I am running condor on a lab of computers at Charles Sturt Uni, Australia... all the computers are the same... If I run it on one of those computers NOT through condor... my job takes about 4 minutes to run.... If I run it through condor... about 1 minute!!!! Now that is really good... but it just doesn't make sense!!!
- If you job produces a lot of output, it will run considerably faster sending its output to a file than to the terminal. (Scrolling a big graphic display can be expensive.) Try timing both of those cases.
I figured this might be the case... so I ran the same job but took out all the printing to screen...... same result... 4 minutes out of condor one minute with condor.
- On your desktop machine, you might be writing your output to a
file system, which can be considerably slower than using a local disk. For example, if your /home directory is stored on NFS and /tmp is a local disk, then "myprog > /home/bob/output" can be considerably slower than "myprog > /tmp/output".
Nope... that is defianatly not the case... all running of the local disk (Windows XP).
Those are just some ideas... Let us know what you discover.
Thanks Doug... I'll just have to keep guessing.... but at the end of the day... I'm not going to stress about it.... It's running my job 4 times as fast :)
