recently we have installed in our lab an Opteron system (Tyan 2882 motherboard, two Opteron 244 processor, 8 GB memory) running SuSE AMD64 9.0 Using the PGI compiler suite we did some memory allocation tests. We found a modest 4 GB memory limit per allocated array. According to PGI engineers this is not a compiler fault, the limit is just set in kernel's mmap.c routine. Would it be safe to change this value and recompile the kernel or it would require changing some other routines?
There's no such limit in the kernel. You should be allocate such an array without problems. Andreas -- Andreas Jaeger, aj@suse.de, http://www.suse.de/~aj SuSE Linux AG, Maxfeldstr. 5, 90409 Nürnberg, Germany GPG fingerprint = 93A3 365E CE47 B889 DF7F FED1 389A 563C C272 A126
