Hi,

It seems that core binding currently isn't typically useful with MPI
jobs. The pe method needs exclusive node access and a fixed
allocation
rule that you need to know in advance, but then you could have the mpi
do it anyhow (e.g. openmpi paffinity_alone) which works more
generally.
(See past discussion.) There seem similar restrictions on the set
method in practice -- at least needing a fixed allocation rule, as you
have to specify a fixed core count.
It looks straightforward to implement binding a number of cores
equal to
the host-local slot count. Does ayone see a problem with that or have
strong feelings how to specify it? I'd be inclined to let bare
`-binding set' do it, but otherwise maybe a new type like `setslots'
analogous
to `set'.
what would be the difference to the current implementation?
