On 2 of my slower computers, the computing time to complete a workunit is about 5-7 days, and on both of them, few work units failed with status "Timed out - no response" when they were nearly finished.

This is such a waste of time, which could be used for other projects, and that is why this app will not be used on my computers anymore until this problem is resolved.

There are other projects which could either calculate the remaining time precisely, and such long work unit will not be started on them, or allow going over the deadline. Rakearch project and this particular app fail in both.

It is sad to see good project ending. I hoped that new search for Rank 11 would be started soon. When I was working on optimized app for R10, I found another possible optimization - check and eliminate rows with duplicated pairs early, in similar way as app is eliminating duplicate values on diagonal. I created a small proof of concept using __uint128_t type. When app was looking for fully orthogonal pairs, it was 2.6 times faster (this probably could be improved). Unfortunately for R10 app is looking for partially orthogonal pairs, so another approach was required, and it was 30% slower. I recall that you wrote that it is easier to find orthogonal pairs for odd ranks than even ones, so I hoped that I could use it for R11 search. I also started work on GPU app. So far results were not spectacular (about 3 times faster on Nvidia 1070), but there is room for optimization. I hope that you will reconsider running R11 search :)

Are you planning an application for raspberry pi 4?

Glad to see you again in the forum! At now, we have no Pi 4, but would you try to run the application for Pi 3 on Pi 4?

I was looking at the partner on a work unit and saw his credit. What is going on??? The credit on this project was about half of what it should be but 0.01 credit for a task is ridiculous for the time it took to complete.

There are a lot of these across numerous volunteers, zombie and Mumps are 2 of these but others also, with the owner of computer 375 having quite a few of them.
Run times appear normal for all.

So a problem seems to be there somewhere.
