</div></div>I need queuing time vs. advertised job walltime on various clusters<br>
(with various/random degrees of utilization). That's to see whether it's<br>
useful to have coasters at all.<br>
<br>
The number of jobs is an orthogonal dimension (i.e. we may want to<br>
measure the queuing time vs. #of jobs for various walltimes, but later).<br>
The actual job duration is not relevant. The amount of data is not<br>
relevant.<br>
<br>
Clouds are an interesting environment, but not for this particular<br>
problem. That's because we need to see how much it takes to acquire<br>
resources, not how fast some job middleware is after we got hold of<br>
those resources.<br>
<br>
