Thanks for shading some light into it!

$./lstopo --version
lt-lstopo 1.0.1

$./lstopo --xml /tmp/2010-Jul-10_22h14m_results/2.6.32-44.el6.ppc64_OS-
indexing.xml a.txt
Segmentation fault (core dumped)

xml was generated with
lstopo --physical a.xml

Output of command: "lstopo --physical -"

L1 (64KB) + Core p#0

Note missing socket.

I will attach:
-xml causing crash (2.6.32-44.el6.ppc64_OS-indexing.xml)
-whole run directory (notice that png, pdf, ... are created (no crash) but are 
empty. Others format are OK (check .fig) ) Please notice that hwloc-distrib is 
also not working correctly - check CPU_AFFINITY/0008.log for example.
-runtest.sh - script used to create the data. 

Let me know if you need more data.

Thanks!

In 1.0.1, there's a patch that prevents us from showing invalid socket
info on old kernels but it also prevents us from showing valid socket
info on recent kernel. I reverted the commit in trunk (and in the
upcoming 1.0.2).

If you do "lstopo a.xml" first, does "lstopo --xml a.xml a.txt" crash as
above? If so, please send a.xml so that I debug this.

[hwloc-devel] hwloc on PPC64

2010-07-11 Thread Jirka Hladky 
Hi all,

I have run into two bugs on PPC64 on 2.6.32 kernel.

Version:
lt-lstopo 1.0.1

BUG #1: No Socket information in lstopo output:

./lstopo
Machine (3654MB) + L2 #0 (4096KB)
  L1 #0 (64KB) + Core #0
PU #0 (phys=0)
PU #1 (phys=1)
  L1 #1 (64KB) + Core #1
PU #2 (phys=2)
PU #3 (phys=3)

Fixed in the latest version (tried hwloc-1.1a1r2301.tar.gz)
lt-lstopo 1.1a1
./lstopo
Machine (3654MB) + Socket #0 + L2 #0 (4096KB)
  L1 #0 (64KB) + Core #0
PU #0 (phys=0)
PU #1 (phys=1)
  L1 #1 (64KB) + Core #1
PU #2 (phys=2)
PU #3 (phys=3)

I have attached /proc/cpuinfo ("bug_1-ppc64-cpuinfo")

BUG #2
On some PPC64, kernel 2.6.32 I have crash when running 
$ lstopo a.txt
Segmentation fault (core dumped)
$ gdb /usr/local/bin/lstopo core.8771
Program terminated with signal 11, Segmentation fault.
#0  0x100060b4 in .merge ()

It appears only on some PPC64 boxes.

This issue is also gone with in the latest version (tried 
hwloc-1.1a1r2301.tar.gz)

I wonder if you are aware of these problems. let me know if you need more 
details.

Thanks
Jirka
