Prime Search at School

2009-09-15, 00:52

Hey everyone, I am a senior at my high school and have thought of an idea to get more computers running prime95. I hope to talk to my principal soon to see if I get get the faculty's computers to start running the program and find more primes, but I just have one question:

Is it possible to run the program when no one is logged into an account? (in other words, when a screen says "press control + alt + delete to begin" can prime 95 be running somewhere in the background).

I ask this because the computers in my library are in this mode all the time and I thought it was a waste to let these computers just sit there without doing anything. If anyone has any ideas on how I can make my project any better or how I can get prime95 to work even in the "log in" mode, please contact me at dragonblast62@yahoo.com

Can't wait to start searching for more primes :]

Use the task scheduler. It will start/stop the jobs at specified times
even if noone is logged in.

I'm pretty sure that if you use the Start at Bootup option (which makes a Prime95 service), it'll run whether a user is logged in or not.

If you try one of the 2 methods mentioned you can test from another computer its actually running from a command prompt:

tasklist /S <ip>

or you might need a valid login for that computer:

tasklist /S <ip> /U <username> /P <password>

You can also remotely schedule tasks:

schtasks /Create /S <ip> /RU "<username>" /RP <password> /SC ONCE /TN <taskname> /TR "C:\program files\prime95\prime95.exe" /ST 10:00:00

This starts Prime95 once at 10 the same day (if path to Prime95 is correct). See more options with: schtasks /Create /?

Use the windows service build. It runs as a service without a GUI and is always on if Windows is booted. http://mersenneforum.org/gimps/winnt2511.zip

A follow up on a related question. I have installed the service in one of our labs on campus and I have verified that the service runs at the login screen in winxp (I ran the GUI first to input my username and set the avaliable memory, and then i went to the cmd prompt in "ntprime -install" and then "net start "prime service""

Now I am just not sure how I can peek in on the work that each client is doing. I see the process but have no way to see that the process isn't having a problem. any ideas?
