Prime95 version 29.4

[kladner]

Running P95 v29.4, Win 7 Pro.
Lately I have started seeing P95 print multiple status lines for the same assignment. See screen grab.

Build 4?

I suspect it is a collection of interim residues sent to the server every 5,000,000 iterations.

OK. Cool. Thanks!

Oops. It is 29.4B3. I'll have to update.

The errors I reported previously have been corrected with the latest version. There are still some cosmetic output issues : on both Linux and Windows the lines about sending the interim results are not ended by end of line characters. This concerns the communication thread and the log file.

Then it seems the interim residues are not always sent when produced, but at communication time. Perhaps this is by design.

On a linux machine where I run two workers the screen output is every 350000 iterations while it is set at 500000 in the settings. Difficult to say if this happened with older versions of the program : that window output is lost :-) One worker does 42M double checks, the other P-1 and "ScaleOutputFrequency" is set to 1 in prime.txt.

In the attched log and output files I prefixed the "offending" lines with "+++ ".

I could save both of them, M12345678 is clearly composite.

I replaced all the AID's of the workunits with the string "AID" and the exponents with 12345678 ... Some people get nervous when they see active assigments data on the forum :-)

Is there a setting to configure the number of seconds for "Waiting (5 * workernumber) seconds to stagger worker starts"?

[Prime95]

No, I can add one for build 5: "StaggerSeconds"

Yes, it is called "StaggerStarts".

Ah, thanks. Quoting from undoc.txt for reference:

Some machines report much better timings if the worker threads stagger their starts. This was first noticed on Core i7 machines running Windows. Presumably staggering starts improves timings due to each worker allocating contiguous memory. You can control how long the program waits between starting each worker. In prime.txt, enter:
StaggerStarts=n
where n is the number of seconds to wait. The default is 5 seconds.
