The IBUCH_ _pYEEI units are also slower on my computer.

Got anybody any of these new v6.09 WUs?

Hi,
yes, today I updated to cuda 3.1, resetted the project. A couple of minutes later the download of all necessary files started. For abaout half an hour I received messages, that I have a wrong system, that a fermi-GPU is required aso.
But then - surprise, surprice - a 6.09WU started. Right now my old GTX260 is crunching it. Usually it faild after ~16%, now it reached 18% .. and it is still working!
I will give an update, whether it finished or failed.

Regards,
Alexander

I will give an update, whether it finished or failed.

No reason to be happy, wu failed after ~2 hours.
So CUDA3.1 + old 260 : Sorry, the problem is still there!

Regards
Alexander

We can reproduce the problem so we can probably fix it.

We know where is the problem. It is due to a change of data structure in CUDA3.1 which seems to be very bad in most cases.
A fix is on its way, but it might require a couple of days.
Be patient in the meanwhile.

gdf

It's a problem of a routine in cuda3.1. We have patched it for now.
New application release coming up.

gdf

We have found a very bad bug in CUDA3.1. I have removed the CUDA3.1 application until we can see the extent of the problem.

gdf

Maybe NV will fix it in CUDA3.2 :)
I hope they will release it in a month.

Are there any news about that very bad bug?

On a machine with a mixed Fermi/g200 installation of cards, results on g200 for the FFT are simply wrong. This is a really bad bug.

The only solution is to deliver the CUDA3.1 application to Fermi cards only.

gdf

New application is out for test in beta. Only fermi cards can get the cuda31 app due to the cuda3.1 bug.
This version maintains the level of performance of cuda3.1 for all workunits.

Picked up two, both failed in about 1 sec!

Same results on my GTX 470...immediate failure

Sorry i can't post the error details ATM but I am fairly sure they identical to skgiven's

This one also failed,

Removed, tomorrow another one.

Trying now with acemdbeta 6.32 for windows.

Ran one Beta task. It worked on my GTX470 on XP x86, Boinc ver. 6.10.56
Cant find it online yet!

I just finished 3 of these beta units, they all came out completed and validated.

These beta WUs are failing on the GTX 460:

While the clock speed is also incorrect above, it's reported correctly by MSI Afterburner v1.61.

The beta's are working well for GF100 cards, just not for GF104 cards (GTX460). The scientists are now aware of the problem because Beyond reported a difference in Compute Capability between the cards; CC2.0 for GF100 cards, CC2.1 for GF104 cards. GDF said they will try to create a new Beta for the GTX460 on Monday. So check back Monday evening. Apparently the GTX460 works on Collatz. Those wanting to test their card & tune the fans for a nice low temps, you could figure it out there.
