Here is some more information about the machine used to compute this: ---------- Forwarded message ---------- From: Oleksandr Pavlyk <[EMAIL PROTECTED]> Date: Fri, May 2, 2008 at 4:29 PM Subject: Re: Today We Broke the Bernoulli Record: From the Analytical Engine to Mathematica To: didier deshommes <[EMAIL PROTECTED]>
Hi Didier, I used Linux, with 64 bit AMD processor: AMD Opteron(tm) Processor 250 cpu MHz : 1000.000 cache size : 1024 KB and 8GB of memory, but as I say in the blog, I did not use that much. The calculations were done using development build of Mathematica, but calculations will go through in any flavor of Mathematica version 6 as well, to the best of my knowledge. Just run Timing[ result = BernoulliB[10^7]; ] It will take about twice longer on 32-bit processors, thus about 2 weeks. Please do not hesitate to ask further questions.
