[mvapich-discuss] [PATCH] Minor startup improvement

[Maksym Planeta]

Hi,

I found out that function umad_get_ca() is called several times inside 
MPI_Init. When the arguments to this function are the same, the result 
is also the same. So I cached the result of the last call. This allowed 
to speedup MPI_Init for 0.9 to 0.5 seconds on a cluster with 24 cores 
nodes each. I tested this with 32 to 256 ranks.

The patch is in the attachment.
