Thank you! When should we expect the change to be fully effective? Should we wait a day to make sure any older 3.1 tasks have cleared the queue?

This will make many crunchers very happy!

Note: Please don't use driver version 295 or 296! Recommended versions are 266 - 285.

On a sample of one (http://www.gpugrid.net/results.php?hostid=93580), last week's 3.1 allocation has been replaced by 4.2

It will be interesting to see if this little 420M laptop can complete it within 24 hours.

This task is 3.1 but should be 4.2

http://www.gpugrid.net/result.php?resultid=5564707

This host also gets 4.2 tasks.

All of my GTX5xx hosts get mixture of tasks. My one GTX680 host gets only 4.2 tasks.

Still getting a mix. ie http://www.gpugrid.net/results.php?hostid=124305

The problem seems to be that your machine is marked as unreliable with the cuda4.2 application, so the server decides to give the cuda3.1 one which is reliable.

I recall I always got some junk at the end of arrays (array size can be any but processing is vectorized to float4) ....

Brook build took fold buffer from CPU memory. And there was guarding zeroes written at the end to allow vectorized fetch.
Now fetch done directly from GPU buffer. And (will check this) no guard elements at buffer end.

I got this error a few times, i solved it by raising the voltage a bit. Or not overclocking as much would help I would think too.

This host is also getting an mix of cuda31 and cuda42 tasks.

Hasn't had an error since i installed the GTX560 in it and started running GPUGRID again.

Not had a 3.1 task since my last post, so looking promising.

Just checked. Looks good. No new mixed tasks for me.

3 Jul 2012 | 16:41:51 UTC Thats the date of my last 31 sent. Its after your 10 oclock. But i must wait for more wus the current one is 42 but this means nothing ^^ 285gtx is slowing barely down on 42 apps so i need more time to wait :/

This computer has not received any cuda 4.2 work units since updating the driver on 6/30/2012. The last one just downloaded a few minutes ago, it was cuda 3.1 also. Any suggestions. http://www.gpugrid.net/show_host_detail.php?hostid=79921
Thanks Jim

Did you try a project reset?

Were sent 3.1 tasks at 7:58 UTC & 8:32 UTC. No more so far.

Look promising. No mixed task so far.

Haven't received any more on my 570

I've received a CUDA3.1 task today on one of my hosts. However, my hosts receive much less CUDA3.1 tasks lately (btw most of them are turned off because we have a heatwave here in Hungary).

Doh! Just received a 3.1 task at 21:19:29 UTC.

I just got a 3.1 a few hours ago.

Thanks - Steve

This problem can be handled on the cruncher's side with my workaround.
GDF, I just want to be sure... Could it generate any problems if I crunch the CUDA3.1 tasks with the CUDA4.2 client? (as my workaround works this way)

Yea I got one (3.1) on my 570 again. Or course it always sneaks in when I'm sleeping. I too would like to know if the workaround is acceptable. I will be putting it in place later myself with your permission GDF.
