This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "MPICH primary repository". The branch, master has been updated via 46dba93ff00afede3c624e462eb3e7ac8e10dcce (commit) from f22b5c90632dd86d146dd275001459b66304c145 (commit) Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://git.mpich.org/mpich.git/commitdiff/46dba93ff00afede3c624e462eb3e7ac8e... commit 46dba93ff00afede3c624e462eb3e7ac8e10dcce Author: Rob Latham <[email protected]> Date: Tue Sep 17 10:29:48 2013 -0500 Improvements to large_type test - large_type now conforms to mpich test guidelines. - additional datatype cases that do not rely on "large MPI_Aint" (but 32 bit platforms probably still cannot process these types) diff --git a/test/mpi/datatype/large_type.c b/test/mpi/datatype/large_type.c index 9449160..bfc32ac 100644 --- a/test/mpi/datatype/large_type.c +++ b/test/mpi/datatype/large_type.c @@ -14,10 +14,6 @@ static MPI_Datatype make_largexfer_type_struct(MPI_Offset nbytes) /* first pass: chunks of 1 MiB plus an additional remainder.
