Message 27236 - Posted: 21 Oct 2010 | 2:39:21 UTC

When I control-C to stop GFN524288 and shut down my computer, and then re-start prpclient.exe, the program re-starts from the beginning instead of continuing from the checkpoint. I confirmed that the checkpoint file was up-to-date (according to the timestamp anyway). Anyone have any ideas? Since it takes about 60 hours to run and I am using a laptop, I really can not just "let it run".

What is the date on your executable? I don't recall if I built it or if it was build by someone else.

I looked into it a little more. David Underbakke must have provided the build. John and I will work with him to get the problem resolved. I have tried to build it myself but am getting roundoff errors, even without any optimizations.

Which build of the client are you using?

I'll try to do a test this weekend to see if I can reproduce the problem.

I've used GeneFX64 2.2.0 dated 2009/10/10 for a lot of off-line testing N=262144 (thousands of tests) with no issues like checkpointing/resuming.
