From 81db125785ed8589a57688afc1fea487aa3818ba Mon Sep 17 00:00:00 2001 From: Thomas Radke Date: Mon, 11 Apr 2005 17:33:00 +0000 Subject: CarpetLib: change the default for CarpetLib::use_waitall from "no" to "yes" Using CarpetLib::use_waitall = "yes" seems to improve Carpet performance both for the standard and for the collective buffers communication scheme. So I made it the default. darcs-hash:20050411173355-776a0-a1046bde7c4ccb4eebc00765b4264701b012c8d8.gz --- Carpet/CarpetLib/param.ccl | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'Carpet/CarpetLib/param.ccl') diff --git a/Carpet/CarpetLib/param.ccl b/Carpet/CarpetLib/param.ccl index 1d266237d..4cd753401 100644 --- a/Carpet/CarpetLib/param.ccl +++ b/Carpet/CarpetLib/param.ccl @@ -33,9 +33,9 @@ INT max_mpi_tags "Maximum number of MPI tags to use" 1:30000 :: "" } 30000 -BOOLEAN use_waitall "Use MPI_Waitall instead many MPI_Wait statements" +BOOLEAN use_waitall "Use MPI_Waitall instead individual MPI_Wait/MPI_Waitsome statements" { -} "no" +} "yes" BOOLEAN combine_recv_send "Combine MPI_Irecv and MPI_Isend calls" { -- cgit v1.2.3
