Top computers: less than 100 sec. for 214 credits (CUDA)
My 4-core Windows machine (Core 2 Quad, 2.83 GHz): 7,000 sec. for 214 credits (CPU)
My new 8-core Mac (Nehalem, 2.66 GHz): 26,000 sec. for 214 credits (CPU, no CUDA available)

Sorry, but I will not waste any more computation power and electricity bill for this. Bye.
