OK thanks Thomas. I'll start playing around with them over the weekend.

Thomas,

Did you update Robert Gerbicz's C code? If so can you post it here?

Carlos

Hi Gary

Welcome to the effort. You will have to decide if you want to work on the Riesel or Sierpinski, and then negotiate with either Thomas11 (Sierpinski) or myself (Riesel) for a E level and a range. There is plenty of spare ranges, its just that there is little point in jumping in willy nilly as it might duplicate work already done, and processing time costs!

If its any help E58 Riesel is hardly touched, you could start from iteration 6 and be in virgin territory.

Robert

Not sure I understood this. I checked your results against the E82 list and only found one candidate on it:

R 66 189598044345983 == R 82 2284313787301

Nice 114/10000 !

I'm a little confused right now. As suggested, I'm running E58 on the Riesel side. I decided to start from scratch and changed the progress.txt file to be iteration 0 and I 0. Not long after starting the program, it stated the following on the screen:

[code]
Build up primetable and their order's up to 134217728.
Done. primepi(134217728)=7603553
c=-1,E=58
[/code]

After 4 hours, it has output nothing more. That is nothing on the screen and there are no new files or file updates in the program folder. Except for the aformementioned changes to the progress.txt file, I did not change anything else in the 64-bit Windows version that Thomas provided for me.

I'm running the 64-bit version of the program "payam64_core2" on one core of an Intel I7 running at 2.9 Ghz.

Is this normal behavior? Do I need LLR or PFGW in the folder? I'll let it run overnight and see if it outputs anything.

That's quite strange. There should be some screen output every minute or so.
And the program updates the progress file at the same rate.

At least there is one problem with the "in.txt" file provided in the ZIP files:
The Nash and Smith checks are disabled. (Sorry for this.)

You should enable them by setting:

nash_check 1

and

smith_check 1


But even if both tests are disabled, you should see some output after at least half an hour or so...

[QUOTE=pinhodecarlos;291648]Thomas,

Carlos[/QUOTE]

The updated C code is included in both files (payam64.zip and payam32.zip).
Note, that I changed only the "book keeping" of the recordtables. Everything else is untouched...

robert44444uk 2012-03-03 15:45

Some records for pinhodecarlos:

Absolute:

27 62 68356548611405 R 66

Riesel records:

62 580 239140284350775 R 66
85 1831 184142873276479 R 66

And of course a total rewrite of E66 Riesel records!

That did the trick. It's now writing to the screen about every minute or so, it is updating progress.txt, and there is now a recordtable. Thanks.

I had checked it after an overnight run of 12 hours with both nash and smith_check set to 0. There was still no output on the screen, no recordtable, and no update to progress.txt.

robert44444uk 2012-03-03 18:08

I got another 88 E82s this week, including one at 114/10000

Shockingly that candidate was only 117/20000 - so sayonara to that!

Another is showing promise though:

440310850049907 with 111/10000 123/20000 133/30000 136/40000 142/52830

Will run this one up higher, poss to 100000
