I think these numbers tell enough to justify any GIMPS-related research in this area - especially as it is available with Linux kernel versions 2.5.36+ and 2.6. Actually (for first tests) it just need a change of the memory allocating and releasing system calls. Last fiddled with by Dresdenboy on 2003-12-08 at 14:33
