What other applications have you used to test the scalability? Have you looked into utilizing OpenMP (available via intel compilers, which are free for private use) ? http://www.intel.com/cd/software/products/asmo-na/eng/compilers/flin/282048.htm I am not sure of the state of GCC's OpenMP implementation (http://gcc.gnu.org/projects/gomp/), but that might be more palatable to some. It seems that there either exist OpenMP benchmarks for shared memory systems or ones could be easily be created for fully exercising (or maybe exorcising;) the system. One thing is for sure, there are a lot of scientific applications out there written using OpenMP that might serve this purpose as well. Cheers, Brett
