Have two 4 CPU SGI Tezro computers and after upgrading them to Irix 6.5.30 they became slower then single processor SGI O2. Contacted SGI support and go no answer. Used to run a job on each CPU but now one job runs a little on each CPU with long pauses between actions. Used to take 4 minutes to run a fortran job and now takes 20. Seems like it no longer knows how to run multiple processor intense jobs. Worked fine with Irix 6.5.21 before the upgrade to 6.5.30. Any idea how to get multiple processor work back.
