Feature request: Enable queueing different experiments at once

[zbeekman]

TAU Commander is currently stateful/context sensitive, even at runtime. So you can't create multiple experiments, select one of interest, recompile the code (with a unique name), then select a different experiment/measurement, recompile the code (with a name to reflect the current experiment) and queue them both up at once. It would be really nice, if it's possible, to be able to pass a flag to TAU Commander at runtime to specify which experiment the run and executable corresponds to. Something like:

tau --experiment ln1-hpgmg-sample  srun ./bin/myexe.sample  # in first batch script
tau --experiment ln1-hpgmg-profile srun ./bin/myexe.profile # in second batch script

It's possible that this isn't feasible due to limitations in TAU or it's dependencies, I'm not sure.

Also, I wonder about taucmdr's ability to handle the simpler case where you're doing a parameter sweep, like a strong or weak scaling study, and the measurement isn't changing but you may want to run multiple trials concurrently. This is the simple case and probably a prerequisite for running different experiments concurrently---if it's not already implemented (I haven't tested).
