Hi all.
Trying to compile the current ETK release on the NASA Ames machine Pleiades, I ran into issues with hwloc. This isn't present on the cluster, so I was using the standard "BUILD" option in my config file. The result was a lot of missing symbol messages at link time.
I found that I could get past this by just not compiling hwloc at all, which prompts two new questions for me:
(1) When do I *need* hwloc? Is it only relevant to systems using OpenMPI? The machine Pleiades uses SGI mpi.
(2) More generally, I try to assess module dependencies from what appears in the auto-generated Thornlist. But you can't tell from this that *any* other thorn depends on hwloc. In particular, SystemTopology shows no dependencies at all:
CactusUtils/SystemTopology # SystemTopology ( ) [ ] { }
... but compilation without hwloc fails immediately unless I comment out SystemTopology as well.
Can hidden dependencies like this be improved?
Thanks, Bernard
