Hi, some weeks ago (mainly in the beginning of October) I reported several problems and I would be grateful if you can tell me if and probably when somebody will try to solve them.
1) I don't get the expected results, when I try to send or scatter the columns of a matrix in Java. The received column values have nothing to do with the original values, if I use a homogeneous environment and the program breaks with "An error occurred in MPI_Comm_dup" and "MPI_ERR_INTERN: internal error", if I use a heterogeneous environment. I would like to use the Java API. 2) I don't get the expected result, when I try to scatter an object in Java. https://svn.open-mpi.org/trac/ompi/ticket/3351 3) I still get only a message that all nodes are already filled up when I use a "rankfile" and nothing else happens. I would like to use a rankfile. You filed a bug fix for it. 4) I would like to have "-cpus-per-proc", "-npersocket", etc for every set of machines/applications and not globally for all machines/applications if I specify several colon-separated sets of machines or applications on the command line. You told me that it could be done. 5) By the way, it seems that the option "-cpus-per-proc" isn't any longer supported in openmpi-1.7 and openmpi-1.9. How can I bind a multi-threaded process to more than one core in these versions? I can provide my small programs once more if you need them. Thank you very much for any answer in advance. Kind regards Siegmar
