Subject: [hwloc-devel] hwloc-1.3.1 assertion failures on Linux/POWER7
From: Paul H. Hargrove (PHHargrove_at_[hidden])

When running "make check" in hwloc-1.3.1 on a Linux/POWER7 system I see:
> lt-linux-libnuma:
> /users/phh1/OMPI/hwloc-1.3.1-linux-ppc64-gcc//hwloc-1.3.1/tests/linux-libnuma.c:53:
> main: Assertion `hwloc_bitmap_isequal(set, set2)' failed.
> /bin/sh: line 5: 21415 Aborted ${dir}$tst
> FAIL: linux-libnuma

I've reproduced that failure with 4 different compilers (3 gcc's and an
xlc).
The xlc-built hwloc-1.3.1 also fails an additional test:
> lt-glibc-sched:
> /users/phh1/OMPI/hwloc-1.3.1-linux-ppc64-xlc-11.1//hwloc-1.3.1/tests/glibc-sched.c:43:
> main: Assertion `!err' failed.
> /bin/sh: line 5: 7077 Aborted ${dir}$tst
> FAIL: glibc-sched

The contents of /proc/cpuinfo are:

> clock : 3550.000000MHz

Let me know of any other h/w or s/w info I can report.
