Hi All
We have been using the Argonne MPICH (over TCP/IP) on our in-house designed
embedded multicomputer for last several months with satisfactory results.
Our network technology is custom built and is * *not** infiniband (or any
published standards, such as Myrinet) based. This is due to the na

Currently there are two options for porting an interconnect to Open
MPI, one would be to use the BTL interface (Byte Transfer Layer).
Another would be to use the MTL (Matching Transport Layer). The
difference is that the MTL is useful for those APIs which expose
matching and other
I had a user ask this, its not a very practical question but I am
curious.
OMPI uses a 'fast' network if its available. (IB, GM, etc) I also
infer that for process in the same SMP nodes the sm (shared memory)
btl is used, even if the job has more than one node given to it? The
real qu
