This is a bit odd, as others have indicated this merely means that this process spends over 70% of it's time in system mode. This means that it spends a lot of time producing output or communicating with other processes or what have you. If this program does purely numerical analysis it should not be doing this, 'strace' or 'valgrind' might tell you more. -- .. __o Øyvind .. _`\(, http://www.darkside.no/olr/ ..
