Vangal,

Certainly, that's a good question.  We use Intel compilers all the
time here (almost exclusively on IA-64 systems).  The issue is not
so much whether PerfSuite is compiled by the Intel compiler (as far
as I know, it can't be because of asm statements), but whether it
follows the same name mangling convention (C/Fortran, I mean).
That's necessary to be able to link if you're using the Fortran API.

The thing to do is to set F77=ifc (or efc) on the "configure" line
when you build PerfSuite - it should then follow the ifc naming convention
for the versions of the API routines that are for Fortran.

We generally build both g77 and Intel versions of the libraries and
separate the two by using the configure option "--libdir=<dir>" option
to specify a particular destination directory for the Intel-compatible
version of the library (e.g., /opt/perfsuite/lib/intel).  That
takes two configures and builds - one with g77, the other with ifc/efc.
For both versions, gcc is the primary compiler for PerfSuite.

Please let me know if this is not clear or if you run into any problems.

p.s. I have been looking into the ch_p4 issue you mentioned and it does
seem that the problem is that the commands constructed and executed
when using MPICH ch_p4 are different that what is supplied to mpirun.  
MPI_Init sets things back in order, but that's after psrun has had its 
chance to do its job (the command line given to psrun does not appear to
contain the name of the executable that's to be measured).  Still looking
into possible solutions.
