It wouldn't hurt to have an SoB user or two give it a try.

I was wondering if it was okay to use with SoB. I'll start phasing it in as soon as prior tests have completed, in case there are any errors in starting part way.
Trying it out now on my i7 64bit linux, so far seems to be working without problems
hmmm seems that it is only starting 4 workers where is normally 25.11 started 8 workers on an i7 ... is this expected?
It says something about running helper threads on a cpu ... haven't been checking if the 4 workers are able to work double as fast or more than the 8 workers yet.
Your best configuration is likely to be 4 worker threads with no multi-threading. Use Test/Worker-windows to change turn off the multi-threading.
Time it to see which is faster.
Yup seems you are right 4 workers on 26.2 is faster, than with 8 workers on 25.11 per iteration time was in the range 0.084-0.091 and with 26.2 and 4 workers the range was 0.034-0.040
Only problem is now to get the 4 jobs that was underway on worker 5-8 moved to worker 1-4 so that once they are done with their current tests they will continue with the ones that was underway on 5-8.
It should work if I in worktodo.txt just copy the lines from worker 5-8 over below the current lines on worker 1-4 right?

Has anyone besides Frodo42 tried this?
Does anyone have timings before and after available?
It should be possible to simply:
1) stop your client
2) Back up your folder, just in case
3) replace your old executable with the new executable (executable only, not your prime.txt)
4) start your client
5) make sure you resumed where you left off and are still connected to the SB server and not to mersenne.org instead.

Guess I better get on the bandwagon and update the Haiku port(s)
Apparently, Prime95 26.4 has been out for about a few days now. So far, this one seems to have addressed the minor bugs from the last release without any problems.
<sigh>
Guess I'll have to update the Haiku port(s) again...
This version has been out for over two weeks now and addresses many bug fixes from the previous releases (26.3 and its three or four builds). How difficult (or advisable) would it be to use this version?
This version also has had a few builds in the two weeks it has been out. If you want to try it, and are not using a Mac, then all you have to do is drop in the correct executable into your current directory. Just replace the executable, not the prime.txt file.

Thanks, I thought that there may be, perhaps, some added settings that would conflict (with prime.txt?) if I simply dropped the prime95.exe or mprime.
If the speed and stability improvements are as they have been purported to be, then this is a worthwhile update to implement.
