Mersenne: christmas computer system?
I'm giving my brother's family a new computer for christmas. He'll buy it from a local (to him) 'white box' pc store and I'll pay for it. I am a little concerned about performance because the pc will probably be running GIMPS and I'd like to get my money's worth. It's easy to request a P4 in the 2.0-2.5 range and 256M-512M of memory but I've read of the bottleneck caused by slow memory and the bus between memory and cpu and I don't know what to specify or how to evaluate components in this area or measure performance after the pc is built. Any comments or suggestions? I want them to have a fast machine but not on the bleeding (expensive) edge. Other than GIMPS I'm sure my nephew will be the heaviest load when he plays games on the new machine. I think I should also request the video card has all of it's own memory, right? I don't want the video to share the main memory for performance reasons, right? Cheers...

Mersenne: Contact Primenet
There used to be an option in Test-Primenet to force a connection. In version 20 this is gone and I miss it. I often dial in for just a couple of minutes. I would like to connect to primenet or Prime95 is already trying, but I may not be connected long enough to use Prime95's periodic connect attempt. Why was it deleted? Can it be brought back?

Mersenne: Prime95 causes screen jitters
I've got my friend's 450MHz PII Aptiva with 256Meg ram running Prime95 under Win98. I'm seeing minor interference on the display when Prime is running. If I stop Prime the interference stops. Not much else is running 99% of the time so it's an ideal GIMPS machine but I'm bothered by the affect it has on the display. I've tried all kinds of different resolutions and sync rates but the ONLY thing that seems to affect it is whether or not Prime95 is running. Any ideas? ...suggestions? Cheers...

RE: Mersenne: The return of poaching?
Let me give you the 'newbie' point of view to all this. I've only been part of GIMPS for a couple of months. It looked like something fun to do, useful for science, etc. and a good way to burn off those spare cycles that keep building up. :-) Here I thought I was part of some great cause and we were only here for the common good. Little did I know there really is a dark side to the force and behind the scenes GIMPS is really Peyton Place. I'm not even sure WHY anyone wants to go to the trouble of filtering out high exponents. Will this result in more LL hours worked and a higher position on the performers lists? Also, what's this about poaching? Sounds like stealing; what is there to steal in GIMPS? The biggest downside to this thread is that it exists at all. It's hard to attract new believers to a cause once they hear about the associated corruption. Cheers...

Mersenne: Self Test
My pc just surprised me by deciding to do a self test after it finished its latest piece of work. The program will now perform a self-tesst to make sure the Lucas-Lehmer code is working properly on your computer. I thought the test was only performed when you first started doing GIMPS processing. Is this normal or has it detected an error in my results? (later...) I got "Self-test 256 passed!" so I guess I don't have any problems. cheers...
