Newsgroups: comp.parallel.mpi From: johnmay@k2.llnl.gov (John M May) Subject: New version of MPI-IO test program Organization: Lawrence Livermore National Laboratory Date: 12 May 1998 18:08:15 GMT Message-ID: <6ja36f$4jo$1@lll-winken.llnl.gov> Our MPI-IO test program, testmpio, has been updated. This program exercises most of the features of the I/O chapter in the MPI-2 standard. In this new version, we have corrected several errors (thanks to Rajeev Thakur, Takao Hatazaki, and others who pointed these out) and added some new tests. In particular, testmpio now tests all of the completion functions for nonblocking calls (e.g. MPI_Testany, MPI_Waitsome, etc.). It also has some tests for the MPI-IO data representation conversion features. The distribution now includes a second program, testrep, that does extensive tests of MPI-IO datarep converters, including both built-in conversions and users-defined conversions. The program includes an almost-complete example of a user-defined datarep converter (the only thing missing is support for distributed array types in memory). You can download the source code from http://www.llnl.gov/sccd/lc/piop/testmpio.tar.Z . This code was developed at Lawrence Livermore National Laboratory by Linda Stanberry and me.
