I do not see OpenCL running on your video card. I suggest you download the drivers again from the Video card home page and all should be well. Looks like your video drivers were altered.


He's got a really old ATI Radeon HD 2xxx/3xxx/4xxx series that did not support OpenCL. He'll likely have to use the CAL applications and I don't know if there's any SETI v8 work for those older apps.

That explains it.

A lot more than just the scheduler is down.

Picked up 92.

Just bragging, and that is 3 computers.

Normally I do not get that many and in the beginning of the run my limits were all governed by the fact that my cache was full.

Well, I'll just chalk it up to weirdness,

If your computer is finishing a WU every 5 minutes you will see the countdown. However, if there is a gap of say 10 minutes between a communication and the next completed WU, you sill not see the timer.
Exactly as Richard said and I have noticed.

No idea if this applies or not, but I just loaded another computer with Win 7 & BOINC, Computer 8010411, and one thing I noticed was that it didn't seem to have a countdown timer running under Status column in the Projects tab. It would happily up/download the new tasks when I hit the Update button, and would even do the 5 min backoff, but after that completed, it then went to blank. The tasks were still running, but they didn't appear to auto upload, unlike all the other systems I had installed recently.

I poked around the settings, and didn't see anything obvious as to why it wouldn't work as expected, though before I shut it down, I think that it might have at some point uploaded some of the tasks itself, but I had to give it a final nudge to get the last 10 or so tasks uploaded. As I was just test running it, I haven't really worried about it, my main concern was hardware errors, but I will have to keep an eye on it when I bring it up again to run it in the farm. Just thought I'd add this to the discussion, in case there are others with this issue as well.

The next time you communicate with the project is will Update. That has been normal for some time (at least on my computers). It looks as if it is not wasting bandwith when there is nothing meaningful to transmit.

Posted 17 May 2016 by Profile Bill GProject Donor

The first thing I noticed is that both of your results state Found 30 single pulses and 30 repeating pulses, exiting.
Where the results for the other hosts did not have 30/30 signals.
They found
single pulses: 6 repetitive pulses: 1
and
single pulses: 5 repetitive pulses: 0
for the two workunits tasks.

It looks like your host isn't returning good results. Often this can be from a thermal issue or overclocking.


I noticed the results as well. I do not overclock and the CPU is running at 50-60C. Did you see that other one that I aborted.....it kept restarting on me and I thought I had tried enough.

Thanks

I am just wondering if there is something wrong with this computer as the 2 APs that were crunched on the CPU both came up invalid.

Generally CPU APs are a rarity on my systems and the worst part is that I am leaving for a week this morning. I will try and see what you advise me while I am away as I will be checking by remote if there is enough bandwidth where I will be staying.

Thanks, I could not find it because IE decided to show me your page from the temp file, not the new page. I did a refresh and it was there as it should be.

Yes, but OpenCL GPU apps need to be updated to rev 3430 after that from my cloud repo.

I ran the Lunitics installer and now the memory usage on the GPU is much more constant.
Where do I find the rev 3430?

IF this is incorrect, How do I correct it? Both CUDAs seem to be running to completion just fine. This computer: http://setiathome.berkeley.edu/results.php?hostid=7965534

It's perfectly correct for stock setup.

I guess I did not realize it was stock as I thought I had downloaded and installed the Lunatics Installer.
Can I just run the installer now?

I am running 3 per card on my 750Tis. I am seeing similar times as others, but what I see is that my GPU memory usage is constantly changing from 30 to 90%,(IN the past it was steady at about 85%) My GPU Meter on the desktop shows this as well as GPUZ. I see mixed units running, both Guppie and non-Guppie. I was wondering if this is normal or has some meaning. The GPU usage shows 85-95% usage most of the time.

Depends on what this particular metrics actually measure. If it measure device global memory domain uncached accesses then it roughly equal to "cache misses" in CPU world. And then, apparently, it's bad thing. If it measures just memory accesses w/o distinction between cache hits/misses... then it's bad thing too but for another reason and quite non-fixable one. It would mean low to not compute-intensive parts of code prevail. In other words, too few arithmetic operations on single memory load. Just the very thing that make app to be memory-constrained.

Instead of Gaussian where quite high computation load per each sample implied, PulseFind very similar to AstroPulse's algorithms. Maybe that's why AMD owners feel different then NV ones with VLAR and AP - better memory subsystem (in older generations at least).


Something I just noticed, and this may have something to do with it. After rebuilding this computer because of some file corruption preventing me from doing a backup of the system, I now have both CUDA50 and CUDA42 WUs running at the same time.

It's interesting looking at GPU-Z while the Guppie VLARs are running. As others have noted, power use drops off when running the VLARs. Interestingly, that coincides with 99% GPU load. When the load drops down occasionally to more normal 85-95% levels, power usage increases again.
So those extended periods of 99% GPU load, while the GPU is busy, it's not actually doing much work.

Ok, I have a problem, win 7 pro x64 says I can't install cause I have an editing bios which requires a gpt partition and not an mbr disk partition, if I go gbt I lose files, like email and paint shop pro 4.12, etc, etc, etc...

Why am I going this route? Cause my win 7 pro Installation blue screens, even in every version of safe mode...


I have had this problem a number of times. The only solution that I have found is to use an external drive to make a backup of my files and then do what the install wants. After that you can bring the files back. If you are using Win7 you can use the WET method, Windows Easy Transfer. That can copy your files and settings and bring them into your new install.

I have spent days getting UFEI to properly see all my drives, both HD and Optical as it will tell me the Optical drive is not UFEI one time, and the next reboot it will be UFEI. I have not figured out what it is, except maybe my MBs are early UFEI and do not offer all the options that are now available.

WET is used on the old running drive first, before anything else is done. The program is found on the OS disk, or installed on your system already.

This might seem stupid, but I put a grain of rices worth on the center of the cpu and let the block spread the compound, since I swapped cpus, I will get 100% coverage before any power is applied.


Not true, you need to spread the paste, usually with something like a credit card to insure the minimum amount between the cooler and the CPU chip itself. There is not guarantee that it will spread on its own.

The pic shows that about 70%-75% of the cpu is covered.


The amount should be right but did you spread I? I am sure instructions call for that. You need 100% coverage to insure 100% contact. There can not be gaps in coverage. I have never installed a CPU without spreading the compound.

If that is what the picture shows, it is just plain wrongly applied.

One thing you can do is to pause all the other WUs and the AP will start. You can then resume the other work and in my experience the AP will finish before the GPU is taken over again.

I did notice that you seem to have APs that have finished without problems.

You cant. But the AP will start at some point. I notice that it seems to take at least 2 days for the APs to start running on my computers. I run 2 APs or 3 WU on my GPUs. I know it seems like the APs will never start, but the do.

The AP, when it starts will just suspend the still running WU.
