What we have noticed is that certain jobs spend from 50% to 90% of their time doing system calls, as opposed to user time. This is reported both by "time" and a command we have here called "monitor". I havn't figured out what sort of code actuall produces this yet. So far, we have only seen it on Fortran code, but this may just be that we havn't run the right (or wrong) C program yet. Optimization levels have no signifigant effect. Changing the type of cacheing similar does nothing. The HP people here havn't a clue. Has anyone experienced a similar problem? Any suggestions? Thanks in advance. Mark Flynn FLYNN@EVALUN11.(EARN BITNET) Departamto de Fisica Atomica y Nuclear Universidad de Valencia Spain
