Dear Steven, I had the parallel version of mpb built for me on a large supercomputer and I ran some test programs. The problem that I am encountering is that the mpb-mpi hangs on "outputting epsilon". I looked through the mpb-discuss forum and I found that this is a common problem. I added the line
(define output-epsilon (lambda () (print "skipping output-epsilon\n"))) as you suggested to one user and in that case mpb-mpi runs fine. So it must be a problem with hdf5. I saw that you suggested configuring hdf5 without mpi and mpb with --enable-debug. However at the same time in the mpb installation manual you mention that "on large supercomputers we strongly recommend using the parallel HDF5". So does that mean the a serial hdf5 wouldn't work at all on a supercomputer or just that it will be very slow? Have there been a workaround found for using parallel hdf5 with mpb? What is your suggestion in this case?
