I just had that error... turns out you can't right-click and save as on the link otherwise you get a html page saved. You need to click it, then click view raw where it then downloads. I don't get their logic in how the page is arranged.



thanks - no it's working as expected.
gtx 980ti running fine, residues match.

both, 64bit and 32bit opencl versions do not start on my 64bit windows 10 machine.
Error (roughly translated ;) ): xxx.exe is not compatible with the running windows version.
The error title bar says: Unsupported 16 Bit Application ??

edit: here is the error as screenshot.
The same error occurs with the sse2 version.

didn't think of that.
this might be it - thanks.

Hey,

i got a curious question about a GFN21 workunit.
http://www.primegrid.com/workunit.php?wuid=484032985

i started it yesterday an there were 3 inconclusive results.
after i finished the wu this morning it validated - but now all 3 (previously inconclusive) results are all valid?

How can this happen?

I can personally Attest, that AMD CPUs Do have a termal protection.
My CPU a while ago was the AMD Phenom X II 940 which i ran on various LLR Projects here. I did in fact throttle down to 800 MHz if temperatures where high enough.

I am going to speak anecdotally here for a moment. I will also preface this by stating that I may have an unstable graphics card even though none of the traditional graphics benchmarks or games have any issue running. If you look at my profile you can see that I'll have a few units with errors from GFN-17MEGA, GFN-18 and GFN-19.

Running the OCL app for GFN-21 and GFN-22 causes my system to stutter so badly it becomes unusable. After a while, anywhere from a few minutes to a few hours, a BSOD will happen.
Today I decided to give the CUDA version of GFN-21 a go to see what would happen. As of this post it has been running for 25 minutes without the tiniest indication that anything is even happening as far as system usability and stability are concerned. It's running fantastically. I will, of course, have to see if it returns an error or not in about 60 hours.

This may be a reason for keeping CUDA around, but if the new OCL acts like the current CUDA then I have no objections.


Kieth, if screen lag is indeed a problem with OCL, then yours is the first response that's potentially useful to me. This is the first I've heard of anyone complaining about screen lag with OCL. Screen lag is common with CUDA, which is why we have a block size adjustment which lets you trade off performance for reduced screen lag.

There's no corresponding adjustment for OCL because there's been few if any complaints about it, and I'm not even sure if such an adjustment is possible with OCL. Because of the lack, or at least rarity, of such complaints, I'm wondering if the usability problems you're seeing are related to the other problems you're having with your GPU. It could be that there's an underlying problem causing both symptoms.


This is not a Problem for me, so i never mentioned it, but Gfn 20-22 has some Screen lag on my System too.
It goes to the extend that i'm unable to use the Browser if a gpu unit is running.

Since i usually suspend boinc when my PC is in use i have no Problem with it.

I'm not sure if the lag did also occure with the seperate apps (i'm currently using the combined app)

Replacing CUDA in favour of OCL (or whatever name you may use for it) seems to be the trend anyway too. POEM e.g. does ist the same way. I find less an less pure CUDA-Tasks (with low CPU-usage) within the world of BOINC.

After all considerations, giving up a core for solving numerous other problems seems very reasonable.


in this case, the combined OCL app doesn't use a cpu core - just as the CUDA application did.

More problems with the combined app, this time around when using Boinc. I found this while using ver 1036, though I've tested 1062 and the issue is there as well (side note, the file transform problem is fixed).

Anyways, here's what happens. At first, it does the crunching as intended. It benchmarks, selects a transform and starts running. But then all of a sudden, performance tanks. Progress bar moves super slowly and GPU usage is minimal. Also, CPU usage goes from "almost 0" to a full core. Looking at the Stderr file:

Command line: projects/www.primegrid.com/geneferocl_combined_1062.exe -boinc -q 1430458^262144+1 --device 0 Priority change succeeded. A benchmark is needed to determine best transform, testing available transform implementations... Testing OCL3 transform...

Benchmarks completed (45.423 seconds). Using OCL4 transform Starting initialization... Initialization complete (1.068 seconds). Testing 1430458^262144+1...

It just keeps endlessly writing the time estimate to the file, instead of actually doing computations. Just a few seconds of it happening, and the stderr file was alread 600KB long - it once happened while I was away from the computer for a while, and it reached almost half a GB in size!

The above stderr was retrieved from my HD Graphics 530; still, it also happens with my GTX 970:

Also, they can't be seen due to primegrid's forum posting, but right after each line, there are a bunch of blank spaces, as if someone pressed Tab or the space bar multiple times.


This issue happens randomly - I don't know how to forcefully replicate it. But I know a few things: 1- it doesn't happen with the standalone apps; 2- it can happen at any time. My 970 was at around 50% work done, while my HD 530 was only at around 9% in the latest occurence; 3- when it DOES happen, both instances (my Gtx 970 and my Intel HD 530) are affected at once. I'm currently testing each GPU separately to see if it happens again, will report back at a future time.

EDIT: Happens when running just the Gtx 970, will see if it happens when running the iGPU alone.

EDIT 2: Yup, happens when running the iGPU separately as well. Again, no idea on what causes it. Switching back to standalone apps until fixed.


this also (kind of) happens on my machine.
on GFN20 and GFN19 the output in stderr.txt appears.
However, the tasks finish and report correctly, altough they take too long (longer than with the standalone apps) and use a full cpu core ...

on e.g. GFN17Mega the tasks run just fine.

I can Do the FMA3 Prime Tests on Windows.
I'll see if i can get app_info working than i can run the boinc tests as well
