[quote=markr;147201]Of course if you just want to do LMH-type work handed out by the server, then leave primenet on, and go to prime95's menus: Test / Worker threads..., and choose from the "Type of work to do" drop-down.[/quote]

so is that the "trial factoring to low limits" option? i had the option tf-lhm set in primenet, but it just gave me about a dozen in the 58 million range which i'd guess are normal factoring assignments

Yes but you will probably see that they are only to 63 or 65 bits.

[QUOTE=Mini-Geek;147359]Does the option to only run at certain times still work? If so, you could run one instance of Prime95 configured for one worker over two cores to only run at certain hours, and another instance of Prime95 configured for two workers over two cores to run at the other hours.[/QUOTE]

PauseWhileRunning can be used to stop one, more, or all workers during a specified time period. Use the "*" option (match any program name).

[quote=James Heinrich;147355]See [I]undoc.txt[/I] -- you can specify the number of workers to pause when a particular other program is running. Note that you can specify the [I]number[/I] of workers to pause (default is all), but you cannot specify [I]which[/I] workers to pause; Prime95 will start with Worker #1 and keep pausing workers until enough have paused; you cannot specifically stop Worker #3 and let #1 and #2 keep running. So assign your most-pausable work to the lower-numbered workers.

I've found a way to pause a specific worker by putting the PauseWhileRunning line under the particular worker section

however, when I have ONE worker with ONE helper thread, I cannot pause ONLY the helper thread, which is my question

also, does Throttle=20 and using one worker use the same amount of cpu as Throttle=10 with two workers?

yet another question, is it possible to set throttle for a specific worker or a number of workers?

You do know that it is run only when otherthings don't want the cycles, don't you? Also, if it is a question of memory paging, run TF's. [U]Why[/U] do you want to [B]so[/B] restrict Prime95.

[QUOTE=garo;147241]Yes George determined that the test was quite useless for GIMPS purposes. It is still useful for stress-testing your computer.[/QUOTE]

Really? That's a surprise; I thought the Self-Test was good for catching faulty computers before they could submit faulty results. Was this discussed in another thread?

garo 2008-11-02 14:03

I t had a very high false negative rate and gave a false sense of security. Much better to just check whether your double-check matched on the v5 server.

Prime95 2008-11-02 15:42

Even a bad computer would eventually pass the one hour test and get real work. The average newbie didn't really pay attention and/or understand the one hour test. The only reliable method to identify bad computers is to manually scan results.txt and/or manually lookup and compare double-check results.

henryzz 2008-11-02 19:31

will the v5 server stop assigning to a computer if it always produces faulty results

Prime95 2008-11-02 20:19

No. As presently configured it will not assign it one of the smallest available exponents. I can change the server to instead downgrade it to double-checks or TFs. Over time we will find the best balance.

I set one worker to factoring, yet
[code]
[Nov 2 16:05:54] Worker starting
[Nov 2 16:05:54] Setting affinity to run worker on logical CPU #0
[Nov 2 16:05:54] No work to do at the present time. Waiting.
[/code]
?
