Parallelism is is actually doing stuff at the same time, usually for a performance benefit, in which case, you aren't going to be using any of these slow FP languages anyways (but there is always Java + MapReduce, which is kind of functional). Your Erlang code will run "faster" relative to single core Erlang code, but if you honestly believe that you are being parallel fast... Erlang's shared nothing architecture is wonderful for avoiding cache misses. (False Sharing) That's a big stumbling block for good parallelism on today's multicore machines. Also, each process having it's own GC helps even more, and GC is an even bigger problem. Go also makes less use of GC than other langs. |
