That's the one I mentioned back here, https://setiathome.berkeley.edu/forum_thread.php?id=80636&postid=1874698#1874698
I checked a couple of those tasks and the CPUs said it was your machine. This is the results I got from My CPU on that task;

The only way to tell which machine is correct it to run the task on a CPU, the CPU is usually right, unless it's one of the Usual Suspects.
Have you seen any when not using -pfb 64?

Ahh yes, I removed -pfb 64 when you mentioned that, but I haven't run many since then.

I did run 50 through without it during maintenance though.

Thanks. Still need to read it... Repo version is in sync enough?


Not quite yet, though I have a copy. Am using this weekend to do that, now that switchover to faster internet is done and teething problems ironed out.

[Edit:] Well that goes much quicker with 20Mbps upload, instead of 1Mbps :)
Cuda multibeam Alpha, Updated client/alpha to Petri's zi3v. Addresses the pulse race condition. Some questions about best Gaussian are being investigated.

Looks like there's another one from a few days ago, https://setiweb.ssl.berkeley.edu/beta/workunit.php?wuid=9835221
I downloaded the task here, http://boinc2.ssl.berkeley.edu/beta/download/3ec/04oc08ab.11260.17659.13.47.23
It's going the be a couple hours before the CPU is finished with it.

I was able to create a Working Win To Go Portable USB drive. Seems to work as advertised including the computer's internal drive being ignored. The problem is I couldn't get the clone function to work so the install ended up being a normal new install needing everything reinstalled, including all those freakin' updates I just got finished installing on the normal install. I think I'll just swap drives between machines and put the normal install on the ATI machine. Then use the portable on the other machine if I need to run Windows for anything. So, I guess it is possible to install Windows 8.1 on two different machines, as long as 1 is installed as a Win To Go USB drive.

Don't know, I found one of mine one count high against a CPU, https://setiathome.berkeley.edu/workunit.php?wuid=2588520990
My CPU says;

Perhaps there is still a little strangeness with the PulseFind...but it's rare.

Message 1876165 - Posted: 1 Jul 2017, 8:57:11 UTC - in response to Message 1876144.  

I decided to run some of the recent failed tasks again on the Mac using 2 different Apps. The CUDA75 zi3v version doesn't like the Unroll fix when using the 7.5 driver in Yosemite, but seems to work better in Sierra with the Cuda 8.0 driver than the CUDA80 App...weird. Most of the tasks are running fine except there is definitely something going on with the Triplets in this task, https://setiweb.ssl.berkeley.edu/beta/workunit.php?wuid=9837856. The Mac Apps didn't like it any better than the Linux App on the 750Ti. Another task, 04oc08ab.15453.21340.13.47.244, gave One bad Triplet. The task 04oc08ab.31484.2526.13.47.116 is another one giving a Bad Best Pulse. The task 23se08ac.6875.22968.6.33.135 worked again on the Mac with zi3v even though it Fails in Linux. Lastly, blc05_2bit_guppi_57834_84204_HIP26017_0003.15096.818.24.47.37.vlar was One Pulse too high with both Apps.

In other Current Events, it appears that the Crunchers Anonymous move to the new Host has Corrupted ALL the Existing Downloads. Not only is the Maximum File size now only 2.5 MBs instead of 20, but, All the Existing files are going to have to be replaced. Hopefully they can be updated soon, some already are.

That's an overflow, SETI@Home Informational message -9 result_overflow
They don't really count as it just means there are more signals than counted and one machine found different signals before they were stopped. If all the signals were counted, it's possible they would be the same.

It seems Summer has hit Finland. When's the last time you didn't see Petri's machine #1?

Oh, how about those Raccoons?

BTW, if anyone can build a working Copy of BOINC 7.5+ that works in the Home Folder of Ubuntu 16.04 Please submit it to Berkeley. I tried it last year and gave up after a few weeks.

Still 43 days before that thing starts, lol... And summer has definitely arrived in the Northern Hemisphere....

Yes, still plenty of time to get a machine up and running with Petri's Special App.
After some tweaking I was able to upload files up to 7 MBs at C.A. So, the new CUDA 8.0 download has all the support Apps in it again,
Linux_zi3v-CUDA80_Special.7z
The zi3v source code is now at the SETI Repository,

Thanks TBarr, I missed that it was an overflow so no problems there.

. . Hi TBar,

. . I installed this new one with the defaults but I have no idea of how it performs on the 970s because these damned SETI servers will not send me work ... :( In an hour and a half all I managed tot get from it was 2 AP tasks which seemed to be similar to the Windows times (but then it is basically the same ap, OpenCL 100). I will try again later when I get time.

Stephen

. . Hi again,

. . OK, this time I am getting tasks from the servers (phew). On Arecibo (norm) tasks runtimes are very consistent at 3.2 to 3.3 mins on the 970s. For the more common (ATM) VHAR tasks runtimes are all within 1 or 2 secs of 1.5 mins. So they are very similar to (as I had expected) the runtimes I am getting on the 1060s (even though that machine is driven by a clunky old Pentium-D and this one by an i5-6600). I am not crunching on any CPU cores for this test and the CPU usage is varying between 20% and about 36-38%, so it is just that bit too high to consider crunching on 3 CPU cores, I would only use 2 to allow for some headroom.

. . After some time I will change from the defaults to turn off BS and see what difference that makes to run times and CPU usage and let you know.

. . Thanks for packaging the AP and MB-CPU aps with the new release. Though I will have to find my way to Arkayn's treasure trove and find an AVX ap for the long term.

Stephen

It looks like we are getting serious about releasing 7.8, or at least testing it. I suppose I could build it once it gets nearer to recommended status.

. . @ TBar

. . OK, I have been running with BS off for about 16 hours and the results blow my tiny little mind.

. . GPU power consumption up about 10 to 15%, productivity up about 15%. GPU temp on GPU-0 now into the 60 C range even with fans at 90% in winter, keeping the room warm :). CPU use holding steady at 52%, I don't think I will bother crunching on the spare CPU core because normal AR Arecibo tasks now run in under 2 mins consistently (like clockwork). The app is finished in under 110 secs but BOINC/manager takes another 6 to 10 secs to close files and move the results to the upload Q. My humble little machine is churning out about 60 plus results per hour . . . Hoooeeeyyyy Bob!

8^}

. . The flies in the ointment are Guppis. Blc05 tasks are still taking about 5.2 to 5.4 mins :( Oh well nothing is perfect. :)

. . The 970s are doing significantly better than 1060s when the stops are pulled out. Now I will wonder how much improvement the 1060s might get from a Ryzen uograde ... 8^}

. . Stephen

Yahooooeeey!

Hi Stephen,
You could try to Ryzenize your other CPUs just by testing with no CPU tasks and no blocking sync for GPU tasks.
EDIT: and I looked at your computers and saw that you have done that.

It would be greatly appreciated. I just tried it again with both boinc-master 7.7 and 7.5. It's a nightmare. The compiler can't find any of the files that are in folders with numbers, such as glib-2.0 or gtx-2.0, without making links to the contained folders. Nothing I do will convince the compiler I actually have libnotify and gtk+-2.0pc right where they're supposed to be, and apparently all the .cpp files in clientgui are missing a {; ...according to the compiler. After that I hit another snag and gave up...again. From the last time I think I remember someone saying there was a copy of wx-3.0 somewhere that worked a little better. But, I can't seem to find it now. Surely there is an easier way.

I found the version of wx3 I was looking for here, https://launchpad.net/~costamagnagianfranco/+archive/ubuntu/locutusofborg-ppa/+build/9539157
Tried it with a new download of bonic-master and ended up at the same place I stopped the last time.
I started a new thread if someone has anything to offer, https://boinc.berkeley.edu/dev/forum_thread.php?id=11719
Doesn't look as though there's much activity over there.

Not sure if you have tried dropping Gianfranco an email. He is one of the Debian maintainers.

I know when DA announced a test version on BOINC-alpha Gianfranco asked for things to get fixed up. I think the whole dev tree is stuffed at the moment.
