Hi,
We are trying to build 'hwloc
1.4.2'
on Linux on System Z. To build hwloc
Hello,
If you are really talking about hwloc, you should contact this
mailing list
Hardware locality user list <hwloc-users@open-mpi.org>
(Open MPI and hwloc are different software, even if hwloc is
embedded in OMPI).
We are getting error
while performing
first step i.e. running configure script.
error message is :
configure:
error: No atomic
primitives available for s390x-ibm-linux-gnu
If we investigate configure
script,
we got to know that it deals with some assembly related
operations in this
part. And, switch-case does not cover Linux on System z
architecture (s390/s390x),
hence it throws error and exits.
This looks strange to me. We do not use atomics in hwloc at all. Are
you really configuring hwloc and not Open MPI ?
Questions: We
have following
questions related to this:
1. Is 'hwloc' supported on Linux
on
system z?
We don't have permanent access to such a platform but it has been
tested (and successfully used) in the past.
2. What exactly this
assembly part is
used for?
It's not used in hwloc as far as I know :/
If you're really trying to configure/build hwloc, please use hwloc
1.6 instead (from [1]), and report the problem to hwloc-users as
explained above. Please include your config.log and configure output
in the mail.
Thanks!
