How can I get R to use more CPU usage?

Question

I noticed that R doesn\'t use all of my CPU, and I want to increase that tremendously (upwards to 100%). I don\'t want it to just parallelize a few functions; I want R to us

If you are trying to run 4 different LPs in parallel, here's how to do it in snowfall.

sfInit(parallel=TRUE, cpus=4)
sfSource(code.R) #if you have your function in a separate file
sfExport(list=c("variable1","variable2",
            "functionname1")) #export your variables and function to cluster
results<-sfClusterApplyLB(parameters, functionname) #this starts the function on the clusters

E.g. The function in the sfClusterApply could contain your LP.
