From ab4127629f7dfd5728691a28928185c8de5fa90c Mon Sep 17 00:00:00 2001 From: MuQun Yang Date: Wed, 31 Aug 2005 11:05:40 -0500 Subject: [svn-r11322] Purpose: Add the known problem for IRIX6.5 C version >7.4. Description: Somehow SGI's MPI implementation doesn't free MPI_TYPE_entries, So for large application to use MPI derived datatype, environment variable MPI_TYPE_MAX needs to be reset.
