I ran 111G112G to get a speed and memory use measurement for interval size 1e7 for wilsontest compiled against gmp5.0, and then 112G113G to get the same measurement for wilsontest2.c compiled against mpir2.4.0)

Thanks rajula for maintaining your reservation page, it is very helpful, and the new green blocks for completed work make it easier to read. You are fast too, sometimes the pages are updated almost immediately.
Now looking at an i5 based system comparing a 1e9 range to a 4e9 range. 1e9 range = 54219 sec 4e9 range = 189560 sec (47390 sec/1e9 range) Some savings. Jeff. Last fiddled with by Jeff Gilchrist on 20110912 at 14:30

You are welcome. I am happy to maintain the list and I try to make updates as fast as I can. I do check the forums quite frequently... Sometimes I am away for a week or so, so expect some delay from time to time.

I just finished my 80e9 to 100e9 range with nothing new that hasn't already been reported.
I will now reserve 200e9 to 250e9. Jeff.
