Why your PPD may differ

PPD is a guide, not a fixed result. Daily output changes with the work-unit mix, including project, points, atom count, and deadline, as well as system conditions such as OS, drivers, clocks, thermals, and power limits.

How to read this

The logical-processor table below provides the detailed split guidance.

  • Leave enough CPU headroom for any GPUs folding on the same machine.
  • Compare split strategies in the allocation table instead of treating the full-chip estimate as a universal recommendation.

CPU PPD ESTIMATES BY LOGICAL PROCESSORS USED BETA

The following data for the Intel(R) Xeon(R) CPU E5-2640 0 @ 2.50GHz is estimated using the average PPD for each logical CPU processor, multiplied by different counts of those logical processors.

PPD data for CPUs is presented this way because folders can optimize their setup by folding on any number of the available logical processors on a project work unit.

The suggested number of logical processors for best results depends on how many GPUs are also folding, so enough CPU bandwidth remains available for GPU folding.

The maximum number of logical processors available on a CPU should only be used on a system dedicated solely to CPU folding with very little other overhead.
