describing each piece of data.
More concretely, for a simple run I get the following names, each of
which are sent over the wire for every proc (note that
I have been running the IMB performance tests and noticed some strange
behavior. This is running on a CentOS cluster with 16 processes per
node and using the openib btl. Currently, I am looking at the
MPI_Barrier performance. Since we make use of a recursive double
algorithm (in the tuned co
I don't know who exactly is on the bug tracking list, so I thought I'd
update here that I finally ran a variety of OMPI r numbers through MTT
and measured the performance with NetPIPE/sm on a woodcrest-class
x86_64 machine. See my update on #1250:
