Re: Mersenne: Entropia Servers

So it appears that the transition of the cgi(s) from Entropia.com to Mersenne.org have finally been made I had understand this would eventually happen. Kinda surprised that this info was up on the mersenne server; I always thought it and the entropia servers were located separately. Oh well, for those of you who wanted to check your account info, here's at least a temporary solution. :) As I recall, George had posted something several months ago about entropia.com hosting the GIMPS domain (mersenne.org) from that point on. I also remember something about a transition of the PrimeNet server from the Entropia to the Mersenne domain. As of 2 or 3 weeks ago, everything had seemed to be moved over expect the cgi(s). (As of last Friday, the URL(s) requiring cgi (including the one above) did not work if they pointed to mersenne.org) From what it appears you must now have mersenne.org instead of entropia.com in *any* URLs that point to the PrimeNet server for complete access.

Mersenne: Manual Testing Forms Still Broken

Mersenne: CPU hours
Can anyone give me the formula for computing P90 CPU hours of work from a Mersenne exponent, for LL tests and for factoring?

I appologize if it got through and this appears to be a duplicate message. I have been having problems reading some of the PrimeNet "world search status" webpages lately; it appears that they only show exponents through 9.7 M. There used to be certain versions of/addresses for the pages that worked; this is no longer the case, as far as I can tell. I intend to use George's status page until the problem is fixed; I have a good idea of which exponents are assigned to me, as I only have one machine!

Re: Mersenne: CPU hours
On Wed, 07 Jun 2000 08:06:47 PDT, Robert Braunwart [EMAIL PROTECTED] asked: Can anyone give me the formula for computing P90 CPU hours of work from a Mersenne exponent, for LL tests and for factoring? IIRC, there is no easy formula for factoring, since smaller exponents actually take longer to factor to a specific depth (there's more candidate factors; see George's math pages). If you have a Pentium Pro or above, you can get a rough idea by taking the time needed by your machine and multiplying it by the clock speed; then divide by about 60 to 70 since PPro-archetecture CPU's are much better at factoring relative to their clock speed. This is my own rule-of-thumb formula, and may have nothing to do with the ones Entropia uses for factoring credit; I suggest that you ask them for that info. For LL testing, head over to the official benchmark page at http://www.mersenne.org/bench.htm and get the per-iteration time for a P90 for the exponent range, or 'runlength', that you are testing. His times are per second, so multiply by the exponent and divide by 3600 for CPU hours, or some large number for CPU years (I don't have a calculator here at school). George's page doesn't presently list a P90, so you might try linear interpolation or use the handy java applet.

RE: Mersenne: Manual Testing Forms Still Broken
I did that modifications yesterday. Now, I get repeatdly the server message "Server busy - please try again in a few moments" when I try to check in results. But I can get my personal account report.
