all have high credit GPU apps...not just Collatz
The commonality is in their use of the GPU that people have attached to their computers. All of these projects have optimized apps for the GPU and are running at high utilization. Other projects, on the other hand, often have not optimized their apps for the GPU. Even within a project there can be optimized and unoptimized GPU apps. There are also cr/effort differences between OSes as well as between ATI and Nvidia. [TMI... the floating point precision makes a difference for some projects.]
Furthermore, GPUs have a far greater number of cores to work with than CPUs. So GPU WUs and CPU WUs are not really comparable. In my case my GPU (GTX 660Ti) has 1344 cores. So while my CPU WU is processing a single operation, my GPU WU can be processing up to 1344 operations.
But going back to the OP, you only stated the CPU time not run time which, usually, is more important for GPU WUs. This is because most GPU apps use very little CPU processing. [If only BOINC would also list GPU time.]
Mid credit GPU projects include:
Albert
Einstein
Milkyway
Moo! Wrapper
Low credit GPU projects...
SETI
Seti Beta
You might as well run the cpu apps as SETI is either so unoptimized or their credit system is so messed up that they value a GPU at a fraction of its potential.
So branch out and test the other projects and see what they are like. I feel sorry for all those that join SETI and never venture further into the Boincverse. |
