Subject: [OMPI devel] Using MTT to test the newly added SCTP BTL

Good morning...

So Brad Penoff and I would like begin MTT tests of the SCTP BTL, but due
to the presence of the .ompi_ignore file, the SCTP BTL source is not
included in nightly tarballs. I was curious if anyone would object to
our removing .ompi_ignore?

I posted a similar message to MTT-Users and a couple concerns were
brought up which I will address below.

The situation at present is that the SCTP BTL only builds on FreeBSD,
OSX and Linux and only if the SCTP is found to be in a standard place.
On Linux, for instance, you need to have installed the lksctp package in
order for the SCTP BTL to build. We also have a --with-sctp configure
option where you can specify the SCTP path should it not be in a
standard location. If SCTP does not exist on the system, then the BTL
will not build and more importantly, will not break the build of the
overall system.

My question now, is it necessary for us to alter the above
behavior (as initially mentioned by Jeff), or is having the SCTP BTL
build iff SCTP is found sufficient?

Thanks in advance for any advice on this matter.
