|PARI MPQS I/O|
When UNIX PARI does MPQS, it uses several temporary files in /var/tmp. Tracing the GP process shows it doing a lot of I/O to these files as MPQS gathers relations. This is so much I/O that it seems to be a bottleneck. My Ultra 10 333MHz is faster than a friend's Alpha 21264 500MHz doing MPQS on >50-digit composites! Is there a way to eliminate these temp files, or at least make MPQS write them less often?
