Control: affects -1 + src:nwchem
Please unblock package nwchem
[ Reason ]
nwchem-mpich had a problem running over multiple nodes with mpich,
discussed at https://github.com/nwchemgit/nwchem/issues/633
It was a problem in mpich which got fixed in mpich 4.0.3, but
currently we have mpich 4.0.2. The workaround for nwchem is to set
the environment variable ARMCI_USE_WIN_ALLOCATE=0
The need for this workaround is documented in a README.Debian, added
in nwchem/7.0.2-4
[ Impact ]
Without this patch, users may be unaware of the environment variable
setting required to run nwchem over multiple nodes (with mpich)
[ Tests ]
This is a documentation update, no source changes, debci tests
continue to pass (or fail on some arches as before, no regression)
[ Risks ]
Documentation update only. No source change. Negligible rish.
[ Checklist ]
[x ] all changes are documented in the d/changelog
[x ] I reviewed all changes and I approve them
[x ] attach debdiff against the package in testing
