That's a loaded question :)

I'm less concerned about talking about alternatives than I am about 
leaving someone out...

It seems to me that for profiling, oprofile is very widely used and 
maintained.  There is a project called TAU, based at the University of 
Oregon, that is also a very good alternative for portable profiling.  
Additionally, there has been an ongoing project at Rice for statistical 
profiling that is called HPC Toolkit (I believe it uses PAPI and/or 
oprofile for the actual sampling). For aggregate counting, you'll find a
utility called papiex, written by Phil Mucci, that does similar things to 
what psrun in counting mode does.

You can find pointers to some of these at the NCSA site:

SGI also announced an open source version of their OpenSpeedShop tool set, 
but I don't have any experience with it, so can't comment (the IRIX 
version worked very well).

I'd be curious to hear what other people think on this subject.

Thanks again,
Rick
