Hi Jeff, That definetly worked for me. Thanks so much for you help. Purify did find some other UMR (unitialize memory read) errors though, but they don't seem to be negativley impacting my application right now. Nonetheless, I'll post them later today in case anyone is interested in them

Actually, I think your program is erroneous -- it looks like you're using number of bytes for the sizes[] array when it really should be using number of elements. Specifically, it should be: sizes[0] = (int) sizeof(tstruct.one); sizes[1] = 1; sizes[2] = 1; sizes[3] = 1; Sinc

To Whom This May Concern: I originally sent this to the users list, but realizing now that this might be more appropriate for the developer's list as it is dealing with issues internal to the openmpi library (sorry for the dual distribution). Please start with second email first. Thanks, Brian B

Hi Jeff, sure like to try to explain the matters. The script check_unnecessary_headers.sh is not smart at all. It checks whether a header, if known, is required due to some content. It does not know about hierarchies of include files, or convenience headers such as bindings.h and would delete the
