Subject: [OMPI users] difference between MTL and BTL
From: amjad ali (amjad11_at_[hidden])

Hello all,

the FAQ page about using myrinet
http://www.open-mpi.org/faq/?category=myrinet

says that

Note that one cannot use both the mx MTL and the mx BTL components at once.
Deciding which to use largely depends on the application being run.

Can anybody give any further clue on how to decide which one to use MTL or
BTL?

Thank you.

Regards,
Amjad Ali
