I'd tend to agree. We should however mention the previous names in the
documentat
We have a static inline in hwloc/helper.h to replace the old
get_system_obj() into the new get_root_obj(). But there are other API
changes in 1.0 which have no similar compat wrapper. For instance
replacing HWLOC_OBJ_PU instead of HWLOC_OBJ_PROC probably broke every
hwloc user on earth. So I tend t
dplace is a general purpose tool for placing applications and doesn't
know anything about MPI. It does do internal accounting system wide to
spread and pin processes and threads. For example if you run a job with
dplace and tell it to just pin your job anywhere it can and another user
does the

Oops, typo indeed, thanks for the proofread.

Does dplace do something clever like reading the MPI rank and
communicator size and try to figure out how to distribute among the
cores so as to maximize memory bandwidth or cache sharing ?

As of SGI ProPack 7 dplace uses hwloc internally to specify stride
patterns. For example:
mpirun -np 8 dplace -c SC a.out
means to pin ranks to every core inside a socket before jumping to the
next socket and doing the same.
From the man page:
For striding patterns any
I discovered "dplace" today. I don't know how many people install/use it
on their cluster, but it's something that looks interesting when you
don't have advanced binding capabilities in the MPI implementation. For
instance, you could do:
$ mpirun -np 8 dplace 0,4,2,6,1,5,3,7 myprogram
to bind pro

You can replace this with svn merge -c $r $otrunk .

Done. BTW, I use the attached helper script to merge stuff in to the branches
(can't remember if I've sent this before or not). It's a trivial thing, but it
reduces the amount of stuff I have to type on the command line.

This needs to be backported to the 1.0 branch, but somebody might want
to fix/improve the text, so I am waiting a bit.
