Was there ever any progress made in getting this to run on each GPU in multi-GPU systems? Sorry if I missed a post about it.

Fantastic to see projects progress on mersenne.org overview page. 70-71 bits to 300M almost clean. Suppose next batch would be 70-71 bits, 300M-400M, 1.9M wus..wow, is that right?

Great job guys! Looking forward to seeing more GPU power after the penthalon is done.

Unfortunately we had a power drop by a factor of 2, before we have finished 150k tests per day, now 80k.

They will come back after the boinc penthalon.

Hey Reb. Are you going to feed the TF with more work or you just awaiting the return of last results? TIA.

No, already posted in the work available thread. There is a problem to request new work running into an error. The admin was already informed.

My wget version is somehow not working right on ubuntu. I have tried the same version on windows without any issues. I will now preparing work on windows not linux. If someone can point out whats wrong there this would be great. Before I had no issues. I also asked the admin. Before it was always working maybe a server change.

when i had similar issues, i found abandoning wget and switching to curl sorted it out

something is broken, before all was fine, using wget under windows now to request work.

here is what Iam getting:
GnuTLS: A TLS packet with unexpected length was received. Unable to establish SSL connection.

What about adding more details on SRBase progress on GIMPS trial factoring?

Looking at these stats as a matrix (line, column) where line is the range and column the bit depth: https://www.mersenne.ca/status/tf/0/0/1/10000

Priority to clean all ranges to 71 bits, on the above link is the 70 bits column.
Right now SRBase is cleaning the position (300M,70 bits) and will go down up to (700M,70bits). Already in the server queue some (400M,70 bits) work. As can be seen 5.1M wus to clean to 71 bits for n range up to 999M.

On a daily basis it is fantastic to see projects progress. Keep an eye on the 70 column and you will see the figures changing, or moving to the right column, or getting out, when a factor is found.

For the overall progress we are cleaning up the 71bit column up to 1000M. This can take some month, after that we are going to 72bit etc. The stats are only updated 1 time per day.

Thank you for the explanation.
Now I understand the meaning of the numbers in this table.

And why are some of the cells yellow ?

I believe the yellow cells is where another action is being made, the P-1 Factoring. See here for all Math approaches: https://www.mersenne.org/various/math.php

If you zoom in onto those yellow cells up to maximum resolution you will see along side trial factoring the n has taken P-1 factoring to two bounds.

Also, as already said here, fixed column and going down, wu speed will increase. Fixed line, going column to right wu speed will decrease.

I think you're right about the yellow cells !
Thank you for your explanations and for your very informative links !

The yellow cells are CPU optimum (old GPU optimum) Trial Factoring depth. Today, everyone with a ressource average like BOINC or those single users, with a modern GPU, should go 2 bit above the yellow line. So yes, at that point, where the yellow line is, some has to change to P-1 and other users has to keep Trial Factoring, if they want to use their ressources optimally. Since BOINC moves breadth first, then unless sometime in the future, the yellow bar moves to a higher bit depth, it should always make sence for BOINC to go 2 bit higher than the yellow cell shows.

And ECM factoring methods are not efficient for factoring such large numbers ?

(Because for factoring numbers of 100 or 150 digits, which I do very often, one switches to ECM methods much faster. We don't test such huge trivial factors.)
