Hi Simon,
I'm having trouble with nested parallel workers, specifically, forking
inside socket connections.
When mclapply is called inside a SOCK, PSOCK or FORK worker I get an
error in unserialize().
cl <- makeCluster(1, "SOCK")
fun = function(i) {
library(parallel)
mclapply(1:2, sqrt)
}
ing key computations
in a seriously faster language, like C++ via Rcpp.
