Greetings: I ran GMPbench version 0.1 (using GMP 4.2.1) on a Sun Fire V1280, and would be glad to provide data and observations about the test and results for inclusion on the GMPbench results webpage (http://gmplib.org/gmpbench.html). Aside from the output of 'runbench', please let me know what information is required. Regards, -JK
