- Configured and compiled and passed "make check" on an x86-64 linux system with MPICH2, even when i manually enabled the "complex derived datatype" and "special collective i/o" options. Oh, good news: with the recent release of MPICH2-1.3.0, "mpicc --version" finally gives you a non-recycled version number. Now you can check for 1.3.whatever or newer and know those two things work. Probably a bit late in the game for 1.8.6 but just letting you know. - configured and compiled on bluegene. Did not run 'make check' but did run the flash-io kernel on 256 processors. I see, thanks to jumpshot, that you now have many processors doing metadata updates before closing the file. for this small test, 21 out of 256 processors (ranks 0-21) do an MPI_FILE_WRITE_AT. Used to all come from rank 0. Neat! Could that final metadata update be done collectively? I think you've explained to me why it could before, but I'm drawing a blank. ==rob -- Rob Latham Mathematics and Computer Science Division Argonne National Lab, IL USA _______________________________________________ Hdf-forum is for HDF software users discussion.
