Hi, I am attempting to use the 'external32' data representation in order read and write portable data files. I believe I understand how to do this, but I receive the following run-time error from the mpi_file_set_view call:
MPI_FILE_SET_VIEW (line 118): **unsupporteddatarep If I replace 'external32' with 'native' in the mpi_file_set_view call then everything works, but the data file is written in little endian order on my Opteron cluster. Just for grins I also tried 'internal' but this produces the unsupporteddatarep error as well. Is the 'external32' data type implemented? Do I need to do something else to access it? I looked in the FAQs as well as the mailing list archives but I can not seem to find any threads discussing this issue. I would greatly appreciate any advice. I have attached my sample fortran codes (explicit_write.f, explicit_read.f, Makefkile) as well as the config.log, output of ompi_info, and my environment variable settings. I am running Fedora Core 4 with the 2.6.17-1.2142_FC4smp kernel. Thanks, ---Tom
