[PerfSuite-bugs] [PerfSuite 0.6.1] testsuite: 9 12 15 18 21 22 23 failed

[miwei <miwei@ic...>]

I run "make check" after perfsuite has been installed, but several fail
occurs. The tests to 
papi and tdom works well after their installation. What 's wrong with it?
The testsuite.log 
is attached.
Thanks for help

Miwei,

Thanks for sending the testsuite.log.  Looking at it briefly, I wonder if 
the reason for the failures is that you are using PAPI version 3.5.0, 
which is the newest release of PAPI.

PerfSuite has not yet been tested with PAPI 3.5.0 and so it's hard to say 
if any incompatibilities have arisen since the prior releases.  I 
hesistate to recommend that you move back to PAPI 3.2.0 or PAPI 3.2.1 as I 
am sure there are many improvements in the newest release, but that is 
something to try if you choose.

I'll take a look at PerfSuite's compatibility with the newest PAPI and 
update you when I know more.

miwei,

I have had a chance to build PAPI 3.5.0 on a Xeon workstation and test it 
with PerfSuite.  I'm able to confirm failures similar to what you 
reported.

The problem seems to arise when profiling, and the failure is due to an 
error return from PAPI of PAPI_EINVAL, which means PAPI thinks it has 
received an invalid argument to one of its library routines.  This doesn't 
happen in all uses of profiling, but does as you point out, and it happens 
consistently.

I'm not sure at this point whether the problem is in PerfSuite or in PAPI 
3.5.0 but will continue to investigate.

I have a couple of suggestions in the meantime:

1. Use the latest PerfSuite 0.6.2 version, not 0.6.1 which is now rather
    old.  This won't fix the immediate problem but has many fixes and
    enhancements that have been implemented.

2. Consider installing PAPI 3.2.1 in addition to 3.5.0 (place it in a
    different directory) and try using PerfSuite with that.  This
    combination should be quite stable.

Sorry for the problems, will post when I know more...

Update on this issue:  I have tracked down the problem and it looks as 
though the bug is in PerfSuite, not PAPI.  It is a use of PAPI when 
profiling that did not trigger a runtime error in previous PAPI releases, 
but appears to do so now.

A fix has also been developed that will appear in the next release of
PerfSuite (hopefully not too far away).  In the meantime, PerfSuite is
still usable with PAPI 3.5.0, but in counting mode only, not profiling.
Prior versions of PAPI should still work OK.

Thanks very much for bringing this problem to my attention.
