[mpich-discuss] mpich and hwloc 2

[Samuel Thibault]

Hello,

hwloc 2 is to be released sooner or later, and it introduces a few API
changes. The build log for version 3.3~a2 of mpich shows:

tools/topo/hwloc/topo_hwloc.c:428:40: error: 'HWLOC_MEMBIND_REPLICATE' undeclared (first use in this function); did you mean 'HWLOC_MEMBIND_MIGRATE'?
         HYDT_topo_hwloc_info.membind = HWLOC_MEMBIND_REPLICATE;
                                        ^~~~~~~~~~~~~~~~~~~~~~~
                                        HWLOC_MEMBIND_MIGRATE

There might also be other issues.

To test against the development tree for hwloc 2, one can use

git clone http://github.com/open-mpi/hwloc.git

Samuel
