Best way to fold?

Post by Wertyuipo »

Hey
Im currently folding with
SMP:2
SMP:2
GPU
Im getting around 3-7k PPD with it
Is there a way to fold quicker and more?
Like using uniprocessors?
Im not sure which one is the fastest

Welcome to the folding support forum Wertyuipo.

You haven't said which version of the folding client you're using(I'm assuming v7 because of the way your wrote SMP:2) and what model of GPU you have and your CPU info.

It doesn't make sense to have 2 x SMP:2. You should finish one of those and then delete/remove it. If you're using an Nvidia GPU you can change the one remaining SMP to SMP:4. If the GPU is an AMD/ATI then the SMP should be changed to SMP:3 because those GPUs require a core/thread on their own.

The SMP is generally faster than the Uniprocessor provided you assign the appropriate number of cores/threads.

You didn't tell us what your hardware was so we're both assuming that you have a Quad CPU in a single computer with a supported GPU. (You can provide more details or not, that's up to you, but it helps us help you -- and there's a spot in your personal profile where it can be stored.)

Using uniprocessors would reduce your PPD, not increase it.

Assuming for a moment that you are not folding with a GPU, a Quad CPU can run one SMP:4 slot or two SMP:2 slots or four uniprocessor slots. The total amount of work done works out the same, but the speed with which the results are returned is radically different Using all four cpus on a single WU will return WUs about 4x faster and using two CPUs on each of two WUs will return work about 2x faster than using one CPU one each of four uniprocessor WU assignments. The bonus system awards more points when you return things faster so the three options I've mentioned are in descending order of PPD.

Adding a NV GPU will increase your PPD. Adding an AMD GPU will decrease the PPD earned by your CPU and increase the PPD earned by your GPU so it may or may not be a good idea, depending on the relative speeds of the GPU and the fourth CPU core.
