Re: [PerfSuite-users] persuite / CRAY XT5

Jean-Guillaume,

There are two aspects to the question you asked: first relates to VProf 
compilation and the error you received, while the second has to do with 
PerfSuite status on the Cray XT system.

The error message you are receiving during compilation of VProf is 
related to the version of the BFD library (part of binutils) that you 
have installed on your system.  I believe 
"bfd_get_section_size_before_reloc" is defined as a macro in earlier 
versions of BFD.  A substitute that may work is to replace the offending 
line in exec.cc with "bfd_section_size(abfd, section)".

The VProf patch that was posted at the NCSA PerfSuite website is rather 
dated, and does not address the above issue.  It appears that VProf 
itself is no longer in active development, with the last release at 
SourceForge dated June 2006.  Due to that, it is likely that 
VProf-related work in PerfSuite will be removed in the future.  Another 
reason for doing this is that more recent tools such as ParaProf from 
TAU and Cube from Scalasca can work with data generated by PerfSuite.

Regarding the other question (Cray XT): PerfSuite has not been ported to 
these systems, and it is likely that it will not work unchanged.  
Although I am not an expert on that series of machine, I believe the OS 
lacks necessary support required for the psrun command to work properly 
- specifically, the ability to preload shared libraries via LD_PRELOAD.  
It may be possible to provide the PerfSuite C support libraries 
(libperfsuite and libpshwpc) on that platform, but this has not been 
tried or tested.
