"I can't upgrade Open MPI on the computing nodes of this system" is false.
Open-MPI can be installed entirely in userspace in your home directory.
If you read the MPI_Comm_create_group paper, there should be instructions
on how to implement this using MPI-2 features. Jim Dinan wrote a working

MPI_Comm_create_groups is an MPI-3.0+ function. 1.6.x is MPI-2.1. You can use
the macros MPI_VERSION and MPI_SUBVERSION to check the MPI version.
You will have to modify your code if you want it to work with older versions of
Open MPI.

AFAWK, there is no user-available way to get cache information on
Solaris, so it's not implemented in hwloc.
Concerning pci, you need libpciaccess to get PCI information.

Just built hwloc-1.11.7 on Solaris 11.3 & SPARC T7-2. Should finding
cache & pci info work? Not sure if I missed some build flags as I just did a
vanilla build.
Poked around in the mailist user and devel archives but didnt’ find anything.

Hi!
So I know from searching the archive that this is a repeated topic of
discussion here, and apologies for that, but since it's been a year or
so I thought I'd double-check whether anything has changed before
really starting to tear my hair out too much.

MPI_Comm_create_group was not available in Open MPI v1.6.
so unless you are willing to create your own subroutine in your
application, you'd rather upgrade to Open MPI v2
i recomment you configure Open MPI with
