I am hoping there are other users of the kernlab package in R who will be able to solve a puzzle. In the past, I've used the relevance vector machine engine (rvm) in kernlab and was pleased to see it use all four cores on my PC (running Windows 8).
But now it only runs on one core and I can't figure out what changed. I've tried switching R versions from 3.0.2 to 2.15.3 and back and installing packages relating to multicore use, but haven't managed to get more than one core running any more.
Anyone know what is necessary?
