Ralph,
on one hand, i do not have a strong opinion about keeping PSM2 i the
v1.10 series
on the other hand, i feel confused by this explanation ...
if PSM2 is simply removed, only one version of ompi can be released,
but there is no way to support PSM2 at all.
how is this better than giving the option to choose which PSM version
(if any) should be used ?
Cheers,
Gilles

I’m afraid that won’t solve the problem - the distro will still feel the need
to release -two- versions of OMPI, one with PSM and one with PSM2. Ordinarily,
I wouldn’t care - but this creates user confusion and reflects on us as a
community.

Ralph,
what about automatically *not* building PSM2 if PSM is built and PSM2 is not
explicitly required ?
/* in order to be future proof, we could even do that only if we detect a
symbol conflict */
we could abort if ompi is configure'd with both --with-psm and --with-psm2, or
simply do nothing
(the end user might know what he/she is doing, and there will be nothing to do
on the ompi side
when this gets fixed by the PSM folks)
Cheers,

Hi folks
I regret to say that 1.10.0 is hitting an issue with at least one upstream
distro. Apparently, there is a symbol conflict between the PSM and PSM2
libraries that precludes building both of those MTLs at the same time. This is
leading the distro to push for release of two OMPI 1.10.0 builds - one with PSM
and the other with PSM2.
IMO, this is a very undesirable situation. I agree with the distro that
delaying release for some significant time as this would impact everyone else’s
users. Therefore, assuming that the PSM team is unable to quickly resolve the
problem in their libraries, my inclination is to release an immediate 1.10.1
with the PSM2 MTL removed.
I’m soliciting input - any opinions?
Ralph
