Prime95 version 25.7

[db597]

How about all the exponents accidentally assigned to "anonymous" during the transition to v25? Can they all be unassigned and "anonymous" be barred from being assigned any exponents?

The v4 milestone report reported an exponent as tested once even if the LL test returned a suspect error code. In the v5 report, tested once means "tested once with a clean error code". Thus, the discrepancy.

How feasible would it for the Prime95 "Status..." dialog to show ETAs for subtasks? For example, when assigned a first-time LL test, TF and/or P-1 may still need to be done -- could the ETAs for these subtasks be shown seperately from the final LL ETA?

[James Heinrich]

Is there any good reason why TF isn't multithreadable? I don't pretend to really understand the math or programming behind it, but my simple mind sees it as a simple series of divisions... is there any reason why it can't split out into x threads and perform x trial divisions simultaneously?

[garo]

Hmm! TF should be multi-threadable much more easily than LL I would think.

ECM stage2 doesn't show the amount of RAM being used in the worker window titlebar the way P-1 stage2 does.

On a related issue, which was previously reported privately, but reposting it here so that there's a record of it:

On the mouseover status in the system tray icon, the string seems to be limited to 127 bytes -- my tooltip looks like this:

47.99% of M1833551 ECM curve 1 stage 2
80.33% of M1834069 ECM curve 1 stage 1
62.36% of M1833457 ECM curve 1 stage 1
30.98% of

I assume this is probably a Windows limitation that you can't do much about; if so then you should probably use descriptors conservatively, especially with 8-threaded processing is coming to mainstream in the next month... even in a style like this you can barely make do for 6 workers fitting in <127chars:

47% M91833551 ECM1.2
80% M91834069 ECM1.1
62% M91833457 ECM1.1
80% M91834069 ECM1.1
62% M91833457 ECM1.1
30% M91833677 ECM2.1

For 8 workers you'd only have room for

47% M91833551
80% M91834069
62% M91833457
30% M91833677
47% M91833551
80% M91834069
62% M91833457
30% M91833677

Got this error while doing ECM on small mersenne number.

I am pretty sure I selected ECM on mersenne and not on fermat number, looks like my preference got switched.

Also, why do I get ECM assignment on a number that as a known factor?

[monst]

Factor5 multi-threads TF. Luigi, do you care to comment...

The Prime95 benchmark writes to results.txt

Compare your results to other computers at http://www.mersenne.org/bench.htm

which no longer exists. That page should redirect to http://v5www.mersenne.org/report_benchmarks/ and/or Prime95 should put the correct URL in future benchmarks.

Repeat a manual com, checking the box to update the expected completeion dates.

You have now had the v5 server assign you the work that you want.

I just tried creating a .txt file called worktodo.add and typed in

[Worker #1]
Test=100000039,75,1

But nothing happened, even after exiting Prime95, restarting, and doing a manual communication... worktodo.add.txt has not been absorbed into worktodo.txt; it just seems to be ignoring the new file.

Because it is a ".txt" file not a ".add" file.
