I am trying to find out if there is any way to create an error-handler or something else that will trap an error exit from the run-time library due to a fortran I/O error, or possibly some openmpi calls or options that will do the same thing.
Let me expand a little. I am working with a very larger fortran 90 code written by many people that uses mpi. While some of the read/write statements have an ERR= in them, not all do and it is a big job to add this to everyone (and not miss some). With some flavors of mpi (openmpi is one) if one process encounters an I/O error that process will crash, and the other ones can hang because no termination/abort signal is sent to them – this seems to be implementation dependent. I have added some c/icc signal handlers and while these work and can be used to send an mpi_abort signal, none of them catch a fortran I/O error. -- Laurence Marks Department of Materials Science and Engineering MSE Rm 2036 Cook Hall 2220 N Campus Drive Northwestern University Evanston, IL 60208, USA Tel: (847) 491-3996 Fax: (847) 491-7820 email: L-marks at northwestern dot edu Web: www.numis.northwestern.edu Chair, Commission on Electron Crystallography of IUCR www.numis.northwestern.edu/ Electron crystallography is the branch of science that uses electron scattering and imaging to study the structure of matter.
