Re: [PerfSuite-users] Problem with psconfig, workaround for building a config file?

[<ol...@ec...>]

Thanks for replying. Unfortunately I have already tried what you mentioned and
had no luck. First of all, the "profil.xml" file contains the following:

<?xml version="1.0" encoding="UTF-8" ?>
<ps_hwpc_profile class="null">
  <!-- ==========================================================
       This is a configuration file that can be used to ask for
       profiling, based on profil().

       $Id: profil.xml,v 1.3 2003/12/27 14:23:51 rkufrin Exp $
       ========================================================== -->
</ps_hwpc_profile>


It is exactly the same as the "null.xml" file (using Perfsuite-0.6.1 by the
way). And if we try to use any of the other config files (all prefixed with
papi) psrun will refuse to execute because the kernel we are running does not
have PAPI patched to it.


So really, we are in a situation where we have no valid config files to use and
are unable to build our own config files. I've spent nearly 2 days trying to
build tDOM and I have read all the documentation provided with it, but no matter
what I've tried it still builds incorrectly. If there are any other general
config files that may be laying around somewhere (especially for Xeon) that do
*not* use PAPI or a guide somewhere to explain the format of the config file so
we could build one by hand, it would really help us out. Thanks once again.
