I've been testing the multithreading capability of Mathematica 5.2 using a twin Xeon box running Debian Sarge with a 2.4 kernel. Unfortunately the kernel crashes when I run Karl Unterkofler's benchmark with: "OMP abort: Unable to set worker thread stack size to 4195328 bytes Try reducing KMP_STACKSIZE or increasing the shell stack limit." I've tried both suggestions to no avail. The benchmark will run fine if multithreading is turned off with "export OMP_NUM_THREADS=1". I suspect the problem is in the threads library I have. Anyone had any luck with Debian say running a different kernel or a later glibc (I'm running 2.3.5)? Cheers, Jeff.
