1) Message boards : Number crunching : NVIDIA-GFN taking 100% of one CPU as well as GPU (Message 104550)

Oh well I really don't know - I'm not using two or more GPUs in one System. I only tested it with one GPU. Sorry! Maybe someone else could double-check it?

hi,

When looking at "top", it reports that the Genefer GPU task is taking 100% of a CPU, not the 0.112 that is quoted in the tasks tab of Boinc Manager.

It is not a big problem, as the throughput is immensely bigger than the CPU could manage on its own -- but is this a possbile symptom of something else that is wrong. And does this mean tht the CPU is creating a bottleneck for the GPU task?

Using latest NVIDIA Linux 375.26 driver (issued mid December)

R~~



It's not only PrimeGrid. We had a discussion about that phenomenon on IRC because I noticed that when I was crunching GPUGrid. Someone double-checked it on his Linux and Windows System and the result was exactly what I noticed: On Linux it's better to use one whole CPU-Core/Thread for the GPU-Workunit.
Hopefully it's going to be fixed at any time...
