Hello again, this follows on somewhat from my earliar posting regarding initial experiences building and running PETSc for the NetBSD platform.
Having built both PETSc and the application that uses it for our NetBSD hosted OpenMPI/SGE grid, I have observed that a large number of file descriptors are seemingly remaining open on the compute nodes within the grid when running the application. I have determined that the file to which these descriptors point is the one that is being passed to PETSc's "-save_to" option. I appreciate this may be something that's only being seen on my platform but I'd like to remove the issue, if only to be tidy. In case there's some knowledge that might speed up my search for a solution out there: 1) are there/have there been/ any known issues with file descriptors not being closed within PETSc, for that file or otherwise, that would inform this issue ? 2) which /routines/source code files/ would be the places to start looking for clues ? We are running PETSc-3.0.0-p7. Kevin -- Kevin M. Buckley Room: CO327 School of Engineering and Phone: +64 4 463 5971 Computer Science Victoria University of Wellington New Zealand
