I tried to compile and run some code that uses MPI and that links to a shared object library provided by a vendor. Both pieces of code (the piece that only has the MPI calls and the piece that only uses the shared object library) run fine. When I stick them together the code compiles but when I run it I get an exec format error. My questions is: it seems reasonable that MPI would have a problem with shared object libraries (in whose memory space is the library code...); is that in fact the case and should I try to get the vendor to provide me with a static version of the library ? Also where I can get information on the details of how and what I can link with the MPI library ? Thanks for any info. -- KY Karl Young UCSF,VA Medical Center MRS Unit (114M) 4150 Clement Street San Francisco, CA 94121 Email: kyoung@itsa.ucsf.edu Phone: (415) 750-2158 lab (415) 750-9463 home FAX: (415) 668-2864
