staff blogs

distributed.net staff keep (relatively) up-to-date logs of their activities in .plan files. These were traditionally available via finger, but we've put them on the web for easier consumption.

It has come to our attention that a problem exists with some of the nVidia CUDA systems running on the Windows operating system. The CUDA system already released is up to version 3.1, while our dnetc application only supports up to CUDA 2.2.

If your graphics driver is designed for a higher version than this, the application will appear to run normally, but will send us junk results. One way to test if you are running a compatible version is to run ‘dnetc -test’. A working system should pass all of the tests.

When dnetc for CUDA systems loads, it shows a line that begins:- ‘nvcuda.dll Version:’. If the version displayed is 8.17.11.9775, your card will produce junk data (which our stats system will filter).

We hope to release a new version of the dnetc application that will support the CUDA 3.1 drivers soon.

We thank you for your continued support.

Moo!
