[Swift-devel] Re: Swift jobs on UC/ANL TG

[Mihael Hategan]

So I was trying some stuff on Friday night. I guess I've found the
strategy on when to run the tests: when nobody else has jobs there
(besides Buzz doing gridftp tests, Ioan having some Falkon workers
running, and the occasional Inca tests).

In any event, the machine jumps to about 100% utilization at around 130
jobs with pre-ws gram. So Mike, please set throttle.score.job.factor to
1 in swift.properties.

There's still more work I need to do test-wise.
