Did you follow the instructions?

The Latest version of BOINC for Testing in Linux. You should check the Dependencies and Execute bits before running. This version should work in Ubuntu 12.04 and above by installing libwebkitgtk from the Package Manager, however, Mint users should probably use the repository version of BOINC .

This version has Fixed the BOINC Manager Tasks view problem that resulted in the view being focused on the bottom of the Tasks page, and Simple View works. If you have an existing BOINC folder in your Home folder expand the download to your Downloads folder, and Stop all boinc Apps. Open the download, Copy the files and Paste them into your existing BOINC folder in Home. Double click boincmgr to launch the Manager.

To expand the file in Linux you need to have 7zip installed, in the terminal;
To install 7zip run, sudo apt-get install p7zip
To install libwebkitgtk run, sudo apt-get install libwebkitgtk-1.0-0


Check that the execute bits are set on boinc, boincmgr, boinccmd, boincscr and switcher on the Permissions tab. Did you check for dependencies?

I see that a few people still have their green stars. The most obvious one is Eric Korpela. I see Richard Haselgrove still has his star. Maybe you have to be in the inner circle or something.

I see we have lost our Special Fundraiser icons this afternoon because of the server work I presume.

I noticed that gbt_splitter#4 got briefly pulled from duty. Now back. I wonder if it was hanging up the output. Really frustrating that my Linux box is still unable to get any appreciable work while my slow Windows7 boxes have mostly full caches.


. . Ironic as it may be for once I have the opposite experience. Both Linux boxes received nearly full caches (over many requests) while the Windows box got work right away for the GPU but struggled over many many attempts before getting any work for the CPU. I had to reschedule WUs from the GPU Q.

I'm absolutely convinced that the project ignores Ryzen machines for work requests. Couldn't get work on the Windows Ryzen either.

I finally had to shut off gpu work entirely for the project and wait through 4 request cycles before the servers finally decided to send me 40 cpu tasks on the Linux machine. I haven't had any cpu tasks from Seti for 2 days now on that machine until just now.

I have never understood why BOINC decides to fill my slowest crunchers first before ever recognizing my fastest crunchers. Ho-hum.

The first step is to get the TBar version of BOINC installed. BOINC 7.8.3 for Linux

Make sure you follow the instructions about setting the execute bits for the apps and also to check for dependencies.

Don't know anything about Lubuntu. If it does not recognize the CUDA library names, you would have to make symbolic links I think.

Ryzen generally likes AVX codepaths but the recent tasks also respond well to the old SSE4.1 apps. There is also a newly compiled AVX2 app by TBar at Crunchers Anonymous.

All the older Linux apps are at the Lunatics website. Linux Seti@Home apps

It is up to you to determine which apps are fastest on your hardware.

But it is nice that D.A. has finally fessed up to what a lot of us were telling him years ago.

Cheers.

He may have 'fessed up' or at least acknowledged that the Credit algorithm needs looking at ..... but the important thing is he actually needs to start working on the problem. At least restart on that action #Issue 2132 that is already posted on the developer site. Only Richard has done anything recent on it. DA needs to start working on it himself or assign more developers. This action should be on the very top of the action list at the next Project Management Committee gathering.

I participate in the tests done in the past, you could compare the crunching times etc but not really the credits since the credit depends on your wingmate hosts performance too. That's one of the problems of CreditScrew. You can't really control the test environment to be sure if your results have really meaning or no.

But I don't think you can make the assumption that for AR= X. Task(A) AR = X and Task(B) AR =X therefore task A = task B and thus credit Task(A ) = credit Task(B). It just doesn't work out that way. BOINC still generates the random number for credit for each task.

I see lots of posts at the vendors that Nvidia stock would be arriving again at the end of the month. Will be interesting to see whether the pricing drops back to normal from the current insane levels.

I don't think you can draw any valid conclusions yet, Rick. I think you have to run the test for a much longer period to stabilize the APR for rescheduled tasks and also to have a much bigger variety of task types. We've already seen that there is a large difference in task times between BLC types and even changes in task times between the same type, specifically the early BLC04's and BLC13's of past months and the more recent versions.

It all comes down to how BOINC interprets the "difficulty" of the task. I've posted about the very large difference in credit awards I see over at GPUGrid.net for CPU tasks. Some tasks got 180 credits and the some other tasks got 7 credits for basically the same running time. It was explained the difference was the size of the molecule involved and therefore the "difficulty" assigned by BOINC in awarding credit.

Anybody from Beta remember how long it took them to get the splitters working there after the server code update?

Thanks for the link Jeff. I guess I missed that thread entirely and see it was the inception of the rescheduler concept.

How would you test for that. Easy enough to run the same task in the benchmark apparatus with a cpu and then gpu. But how do you submit the same task to the project for validation and credit award?

You can find out all about Credit new here.

Always good to provide the link to the explanation of CreditNew when the question arises anew. Thanks, Grant.

Rick, I misunderstood your move was not bunkering, but in fact just rescheduling. Since that was the case, your APR for the original gpu tasks and the CreditNew algorithm are not in sync since you processed them on the cpu with an entirely different APR. That explains the discrepancy in credit awarded.

You get 50 credits per task. Thank you CreditScrew.


You're getting 50 credits per task?? Who did you pay off?? WHO!!!!

edit...

Tell me!!


Chuckle! It looks like that brief tail-end of the tapes yesterday in between the BLC05's and the new BLC02's, specifically the BLC13/14/25's are awarded more credit than the fast BLC05's. I'm seeing shadows of the normal Arecibo credits in the 70's and 80's.


Next 20
