So i started cpu mining riecoin again just for the heck of it, i have a dual Xeon E5-2670 so 16 threads, 32 cores, I am using xptminer2 from the riecon.ovh site but i only seem to get about 80% usage when using -t 31 (as it does cores + 1.
Is there a better miner to get closer to 100% efficiency?
[EDIT]
Am i able to use
https://github.com/gatra/cpuminer-rminerdFor riecoin?
Try running two instances with -t 15, pinning each to a socket or NUMA node. Pinning the miner to each numa node has worked well for me, especially on dual socket Xeon E5 v3/v4 CPU's.
