it's not necessarily the OpenCl that is going to crash the work either.

For ATI driver installs I tend to be a bit over zealous and anal about their installation. It saves time later trying to figure out what failed

That has been true for a long time. At least since I got the first Radeon AIW. Which was before they started using numbers to identify products. Back then they actually had an uninstall utility that did a good job of removing all of the driver bits.

Looking through clinfo the card's work units are 128 but if I use the settings you suggest for <256 Boinc doesn't register a GPU, but using on the settings in the image works! I will leave it to run and see how it goes from here!

I would like to thank you all for your input.

If the workgroup size is 128 then the applications selected in the image will not work. BOINC may download tasks and try to process them with those applications, but it will just result in errors if it attempts to run them.

Seems not right that his HD5450 should only have a Max work group size of 128, when my HD4850 has a Max work group size of 256.

Your 4850 is considered a high end GPU while the 5450 is considered low end.

Dammit arkayn, I always fall in the same trap "the higher the number, the better"

LOL

Just start ignoring the first number and concentrate on the last 2 or 3.

x850 and x80 are high end.
x770 and x60 are middle of the road.
x450 and x30 are low end.

I'll see what happens at the end of the work unit and see if it returns an error if it does I'll try another setting and wait!

---

If the result come back as corrupt then I will try the other settings again!

This is on my daughters PC and I have only just installed the card but it is registered there. Here is the link to here PC http://setiathome.berkeley.edu/hosts_user.php?userid=9431135

Hmm it runs OpenCL,r390 with a card which have a Max work group size of 128. According to the release documents that should not work, but this completed WU says it does work:

Task 2344581713

Someone more knowledgeable than me should comment on this.

I thought it strange too, perhaps the latest drivers fix this problem?

Claggy

I find it a strange one, if it continues to report successes and the other settings fail I will reset it to work in this manner.

I have just noticed that you seem to be running 2 different GPU's in your system! http://setiathome.berkeley.edu/hosts_user.php?userid=35858 Do they work ok together or are you just running one unit and the other was an older card?

I've actually got two mixed Nvidia/ATI hosts, both hosts GPU's coexist with minimal probems,
the only thing to note, is that when installing drivers, for correct OpenCL operation, the AMD drivers need to be installed last,

Claggy

I guess once setup it was OK but I bet it was a pain initially to get it to work properly?

Yep, getting ATI drivers that would co-exist with Nvidia drivers was a pain for a while,

I imagine it was only a problem with 3x and 4x cards.
I have seen more than one 5450 running OpenCL apps.
Also with older drivers.

Maybe the new APP or both the app and driver. This is certainly interesting news. Maybe I'll see if this works on the HD6370 in my notebook as well.

Sure not the apps.
We tested special versions with suboptimal success at Lunatics.

I went ahead and fired it up on my notebook and it seems to be moving right along. I'm pretty sure I trashed the first one, but that was my fault. So we can see how the next 3 do. I have since set NNT. As the notebook doesn't have any thermal monitoring for the GPU nor is there a separate cooling fan.

The overnight news is once the PC was shutdown for it's overnight rest it's seemed to lose OpenCL I don't see any reason for it and I am 100% certain it's not a BOINC issue but a driver issue! I will seaarch out some older drivers and try those!

Oops just noticed I am on my daughters account!

Peter

I have been looking through the web and found that people do have a problem with this happening. So I ran a program that removes the install information (after un-installation) to remove any pointers to corrupt files and settings! This seemed to do the trick! I am now testing the PC again for any further defective drivers and OPenCL problems! I did notice that ATI have released an openCL update which is on the Lunatics website so if this fails again I will try using that version instead.

Incidentally, I am running Lunatics as mentioned in my earlier posts, which should not work but does as using any other settings fail. I am keeping everything I can cross crossed!
