P-1 factoring anyone?

But, it doesn't seem to update the lines at all. If they start out N/A (from GPU to 72) they don't update. I also tried one from the site in your step 1 and that didn't change either.

A few questions:

Do you add the assignments to worktodo.txt or worktodo.add

What would a typical line look like before the communication

For your step 3, do you do anything special to get Prime95 started communicating or do you just wait for it to do it itself?

Should this work with P-1 assignments from GPU to 72?

Thanks for the help.

N/A means Not Assigned (to PrimeNet).
These will never update.
TF and P-1 GPU to 72 assignments are all N/A.

Though I thought assignments from James' site were NOT N/A and would get updated?

Thanks for the info. You're right, his assignment's are not N/A. I forced a manual communication and it talks to the server but never changes that line. Maybe I'm not waiting long enough or selecting the option?

Can I ask what line you are expecting to see a change on?

Worktodo.txt line should look like:
PFactor=<long alphanumeric string>,1,2,<exponent>,-1,72,2
(Unless you selected PMinus in which case it looks a little different but close)

This is the line I copied. I took a line from James' page so I could practice with the self-assignment. I don't have the <long alphanumeric string> because I thought that is what I was expecting when PrimeNet assigned the number to me (or make it N/A) which would mean it's probably assigned to someone else.

Pfactor=1,2,11201131,-1,64,2

Assuming that is the actual exponent: per the following it is not assigned to anyone:
http://www.mersenne.org/report_expon...&B1=Get+status

The line looks correct. When you use the client menu to contact primenet (and I am assuming Windows because I have not used the Unix/Linux version)
it will either give you an assignment key and tell you the computed completion date
OR
it will give you an error that says something like: "Invalid assignment; already assigned".

The only idea I have is that when you contact the server are you also checking the line that says:
"Send new expected completion dates to the server"?

When you click
Test...
Status
does the assignment show up with a completion date?

If not (and I am grasping at straws here) the line may not be in the correct file (worktodo.txt) in the Prime95 directory.

Or try to exit (not just close and it minimize to the traybar) Prime95 before editing worktodo.txt

An update.

Earlier I had tried putting it in a .add file, stopped and started and then forced comminication with updated status but it didn't give me an ID.

I just checked and after about 2 hours it updated with an assignment ID. So, it worked I just had to wait.

It takes some time for Prime95 to pull the contents of worktodo.add into worktodo.txt (but with the advantage of not needing to stop/exit/restart Prime95). If you want to make sure your assignment-registration is processed right away, you can stop and exit Prime95, edit worktodo.txt, and then restart Prime95. It will most likely immediately contact the server to register all the unregistered assignments it now finds in worktodo.txt

I recall reading about this a couple years ago in other threads....

I have a P-1 that is sitting at 100% for several minutes.
When I check that Status... it reports back the current minutes as the expected completions time....and has been doing so for about 10 minutes now.

I am running 2 workers on a Q9550 with 2 cores each.

Never mind.....it finished just as I sent this.... :embarassed:

Still seemed to be stuck on 100% too long though.

The GCDs at ends of stage 1 and 2 take several minutes -- might one have been in progress?

IIRC the titles and icon statuses never mention the GCD.

- - -

Low-priority request for prime95/mprime: when the GCD starts, change the "100%" on those lines to "100%, but GCD still in progress" or something like that.
