Got this with both ver. 1.24 and 1.25 of the application. The machine in question is a Pent D 830 (running only PG PPS sieves on CPU & GPU at the moment) with XP Home. It includes a dual GPU set-up with an 8800GS and a 9600GSO (same thing just with NVidia's lovely rebranding). Both GPU have 384mb of GDDR3. Driver version is 191.07.

GPU-Z report 97%-98% load with 11% memory load and 97mb used.



EDIT: Followed the logging using GPU-Z through a couple more errors, but no memory usage spike is evident. Indeed, after the next one failed, the mem. usage dropped to between 46mb and 54mb?

Any ideas? Is a driver update required? If so, that would be odd since both these machines were used to test the app in the CUDA test thread.

Hi,
pps 1.27 for linux seems to be broken: I encounter a similar error as Scott since my computer upgraded from "Proth Prime Search (Sieve) v1.24 (cuda23)" to "Proth Prime Search (Sieve) v1.27 (cuda23)"

All computations fail since this switchover; they get killed after an hour. Also others seem to see the same problem, as the same work unit gets handled by several people unsuccessfully with v1.27, see e.g. http://www.primegrid.com/workunit.php?wuid=128271014

Can you revert to v1.24?

Thanks,
Rüdiger

Sorry for the delayed reply...was called out fo town unexpectedly.

In any case, I tested the current version from the test app thread:

Average processor utilization: 2.00 (init), 0.01 (sieve)

No problems there, but the 1.27 version of the released app has the same errors. Going to try a driver update since the 191.07 version on this machine is quite old and see if that helps...



EDIT: The driver update appears to have solved the problem. PPS CUDA work now completed and validated with latest driver (258.96).

Hi,
as Scott seems to have solved his problem, shall I create a new thread for 'my' problem? His solution is not suitable for me, as I am using the latest driver (258.96) already.
