Nice, it's a bit faster :-)

Posted 1961 days ago by Chipotle
I should probably get Iain to compile a Mac version too so Chipotle can test it. But the beta he compiled would also work - just a little slower in a few cases.

Happy to test it for you :-)

Was there anything in stderr.txt when it exited early?

Sorry - I'm a poor tester. the later run clobbered the stderr.txt of the first. I'll attempt to recreate it. In the meantime...

I am seeing inconsistent results (here are two runs, note that the lists are only mostly alike):

Thanks for the quick reply!

BTW, I just ran the first program again, this time getting the expected 44 results. Unfortunately there may be more than one bug, since last time, after substantially fewer than 44 results, the program exited early - it didn't announce the number of factors :-(

OK, so I tried again, this time understanding your instructions better. But why use cuda library for ATI (see below)?

I know it doesn't sound like it, but this is great news! You can reproduce the problem, so you can help us fix it. Could you please run these programs on it:

http://www.primegrid.com/download/primegrid_tpsieve_1.39_x86_64-apple-darwin__atiPPSsieveMAC
http://www2.epcc.ed.ac.uk/~ibethune/files/tpsieve_cl_mac.zip

with these arguments:

-p13120716e9 -P13120725e9 -k5 -K9999 -n6000000 -N9000000 -T -M2 -c 60

And let us know the results? Thanks!
