I'm running r 2. on a mac running 10.6.4 and a dual-core macbook pro. I'm
having a funny time with multicore. When I run it with 2 cores, mclapply, R
borks with the following error.
The process has forked and you cannot use this CoreFoundation functionality
safely. You MUST exec().
Break on
__THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONALITY___YOU_MUST_EXEC__()
to debug.
If, however, I crank the # of cores back to 1, it runs just fine.
The code looks as follows:
mmi_fits<-mclapply(responses, function(a_response){
gmult<-glmulti(glm(make_formula(a_response, sp),
data=df, family=binomial))
return(gmult)
},
mc.cores=2)
