Actually, it was a bug the Falkon provider, there was a tight polling
loop on a task queue even if it was empty... it got fixed with one line
of code :) its now running the CPU relatively idle for Nika's workflow
which doesn't require high throughputs.<br>
<br>
Thanks Yong for fixing it!<br>

<pre wrap="">It was running something like 68 jobs in 15 minutes. Kinda scary if each
of those jobs needs 15 cpu.seconds on the submit side.

<pre wrap="">That can either be good or bad. If the CPU is used doing meaningful
stuff, then it's good. In other words, I'm guessing that the job
throughput is also higher with Falkon.

<pre wrap="">Yesterday, I was playing a bit with Ioan and Nika - they submitted a 68
node / 15 minute workflow through provider-deef & falkon and saw the swift
JVM on the submit node using about 100% CPU; then the same workflow
running through the GT2 GRAM provider rather than provider-deef and falkon
appeared to use significantly less.
I wandered off at that point so don't know if any interesting results came
after.
