The `running as service' is exactly what you're looking for (in the Options menu). Just be sure to remove Prime95 from the Startup menu (where, for some reason, the installer obviously puts it -- argh!) -- if your pupils don't really know what Prime95 is, consider LockUserInfo=1 (see undoc.txt) and possibly `No Icon' too. (Side note to George: Would it somehow be possible to include computer IP in the selection of what prime.ini file to use?

Mersenne: running prime95 while a login screen is active
Hi I have currently the opportunity to run prime95 during the summer holiays in the computer lab of a college. At the moment, all clients were started manually in a special account. When school rebegins in two weeks this would not be possible any more. So i have to install prime95 in a way, that starts automaitaccly at each login. These pentium computers are running win95 and a novell network (but the win95 login screen). Each pupil has an own login Is it possible to install prime95 in a way, that it runs always, even while the login screen is active? What about 'running as service'? --- p-1 double chack: At the meoment a p-1 test will be performed before each firstLLtest and each Doublechack. As far as I know primenet does not save these results, so each p-1 test will be done twice. Is it possible to avoid that? At the moment, it is possible to look up the exponent in Eric Hahh's list, which is quite unwieldy if there are many exponents, and not everone is sending the bounds to Eric, either.

There are *many* blind people who rely on speech output of on-screen text. A friend of mine gradually loses eyesight and is beginning to train for using the speech output. Ever since I saw that, I kinda loathe web pages with only a huge clickable image map on them. Text info on all elements of a web page is a *Good Thing*, even if you dont count those who use old browsers or prefer surfing with images switched off.

The "best" choice here depends on the type of Sparc, how many hours per day you'll be getting on it, and your taste with respect to assignment type. If you like to be able to turn something in at least once a month or so, double-checking is the way to go. DCing is also a better use of the cycles on hardware where there is a significant relative performance drop in going from DC to first-time-test sized exponents. Interestingly, an old Sparc 1 is often better in this last regard than a top-of-the-line E450: the Sparc 1 shows lower relative performance at DC-size exponents, but suffers little or no performance degradation at larger runlengths. So if you don't mind waiting 3-4 months for a result and prefer doing first-time tests, go ahead and set your old Sparc to doing one. > Are there binaries for Mfactor for Sparc/Solaris? I found Mlucas binaries but > not Mfactor binaries. I don't have a f90 compiler. No Sparc binaries at present, but Mfactor is written (not by me) in ANSI C, so just follow the compile instructions in the source code header. One caveat, though: for sieving up to depth 2^53, Mfactor performs OK on the Sparc because it can use the FPU to help with the double-width integer multiplies. However, the Sparc truly sucks at integer multiply (Jason Papadopoulos likes to say that this is the *only* thing the Sparc sucks at), so for sieving beyond 2^53 the Sparc will be pretty awful. You'd be better doing the factoring on a PC (or not at all) and using the Sparc for LL testing. > I suppose that LL results are 100% identical to Prime95 results, so LL test > will be accepted by primenet server in manual assignment, right? Yes. You do need to paste *only* the exponents into the Mlucas worktodo.ini file. When your latest job finishes, copy the last line of results.txt (or of the *.stat file corresponding to the exponent in question) into the PrimeNet manual tests form and submit. When reserving exponents, I suggest you ask for the maximum amount of time (120 days); if the exponent isn't done at the end of that period, you can extend the assignment by another 120 days. Which CPU type you report to the server when requesting work is up to you. I usually enter "Pentium" or "PII/PPro" so as to get a reasonable amount of work (I'm not sure what weighting factor the server uses for machines entered as "Other".) I suspect other Mlucas users do the same, which means that non-x86 machines are underrepresented (relative to their true numbers) on PrimeNet's world test status page. > If I use the manual assignment pages at PrimeNet, will I receive time credits > at Primenet status pages? Your manual test work won't show up on the PrimeNet server's pages, but will appear on George's master list, www.mersenne.org/top.htm and ...top2.htm ). I'm somewhere between #200 and #300 on the top2.htm page, and 90% of that work is from Mlucas manual tests. (Admittedly, I have access to slightly more hardware that a single Sparc, but every contribution is valuable.)

<< Yes. There are *many* blind people who rely on speech output of on-screen text.>> A good point, and the ALT tag is very useful. But although blind people and people with Lynx can't see images, that's no reason not to use images at all. Images + ALT tag is the way to go. Likewise, just because ancient browsers which make up 5% of all browsers out there can't see PNG, that's no reason not to use PNG at all. PNG + ALT tag is the way to go.
