Boinc manager optimisation for best hardware use - Page 2

post #11 of 13
Many tasks are not suited to GPU crunching, even if they were to be ported to OpenCL or CUDA. This is due to the architecture that GPU computing relies on. Generally speaking simple and highly parallel functions will perform very good on GPUs. More complex functions, require more complicated math and instructions, and will be more efficient on a modern CPU.
A good BOINC example of this is Asteroids@Home. The GPU app is really not that much more efficient than the CPU app.

It doesn't help that there seems to be a decline in double precision performance in consumer GPUs in the past few generations. It's probably because NVIDIA and AMD want to protect their Quadro and FirePro sales.

It sucks for me because I've decided to focus my attention on a few projects I really like, Einstein, Milkyway, and POEM. I think both Einstein and Milkyway are double precision thumbsdownsmileyanim.gif.

Edit: Apparently I was wrong about Einstein, it's single precision. I'm still not happy about the situation tongue.gif.

You must be new here. Last I heard, Intel CPUs run BOINC quite comfortably at 80C, and they don't experience thermal shutdown until around 100C.
