You were running the "lunatics app" on this machine, however it appears that you no longer are. The stalled tasks were running under the SOG app from lunatics, which requires Open CL, this is not included with drivers from Microsoft, you must download drivers from the Nividia website and nowhere else. What seems to have happened is you have reverted to the stock application which uses the CUDA drivers which are included with Microsoft drivers.

So the answer is to download and install drivers from the Nvidia website, then re-install the lunatics app. This should then allow the "GPU missing" tasks to start and also the new task you have will then be processed by the lunatics app which is faster .

Your other machine with the 1050 2 gb is running the SOG app and completing tasks in around 15 minutes whereas this machine running the stock CUDA app takes 30 minutes

Post here if you have any more questions

O.K that did it, i had downloaded and installed the nvida drivers, but the glitch, update and reboot obviously did the change, thanx
To increase my poor knowledge, i do not know to what you referto by he lunatics app?

thanx again

To increase my poor knowledge, i do not know to what you referto by he lunatics app?

Lunatics refers to a group who have developed what is known as an "Optimised Application" .

The stock application is designed to be "one size fits all". So by design is not optimised for speed.

The Lunatics Optimised Application has been designed to work on different setups with different CPU's and GPU's for optimum speed an accuracy.

At sometime you must have down loaded and installed the app as it is running on your other machine. More than that you have selected the SOG (Signals on GPU) part of the app.

This app provides much faster processing times on GPU's.

From what you have said I now believe that the Lunatics App must still be installed, but as it required the missing Open CL part of the driver, Boinc when ahead and downloaded work units for the CUDA driver which was working. If by installing Nvidia drivers the "GPU Missing" work units are now running then hopefully all is well. Just need to keep an eye on them to make sure they process OK>

Both computers with the GPU's are refurbs, and I try to do the minimum to get BOINC running, and do not check what is present on the machine if is runs ok out of the "rescue box". Will have to check out the next one a lilttle more i guess.....
thanx for ur help......
