R help - May 2023 - mclapply enters into an infinite loop....

Dear members,
                         I am using arfima in an mclapply construction (from the
parallel package):

Browse[2]> LYG <- mclapply(LYGH, FUN = arfima, mc.cores = detectCores())
^C
Browse[2]> LYG <- mclapply(LYGH[1:10], FUN = arfima, mc.cores =
detectCores())
^C
Browse[2]> LYG <- mclapply(LYGH[1:2], FUN = arfima, mc.cores =
detectCores())
^C

You can see that I am aborting the execution of mclapply. It doesn't finish
even if I reduce the elements to be iterated over to 2. Why is it entering an
infinite loop?

Please exhort me if this is to be posted in HPC list.

THanking you,
Yours sincerely,
ALSHAY M KULKARNI

It does not look to me like you are providing the necessary arguments to arfima.

Try making this work with lapply first... then try mclapply.
