<p dir="ltr">Hi,<br>
Erlang can start a process on another node. <br>
So Erlang can also be nice for a distributed single Cpu cluster of nodes.<br>
In a sens Erlang is always multi Cpu, then.<br>
Regards<br></p>

If you're not running SMP, then you're not really doing what Erlang is excellent at, right? You could just as well be writing C, Java, Lisp, or name your own language that doesn't have a great, built-in concurrency model. I'm a relative noob, though, so what do I know?</div><br class="gmail_msg"><div class="gmail_quote gmail_msg"><div dir="ltr" class="gmail_msg">On Tue, Apr 4, 2017 at 1:08 PM Tristan Sloughter <<a href="mailto:t@crashfast.com" class="gmail_msg" target="_blank">t@crashfast.com</a>> wrote:<br class="gmail_msg"></div><blockquote class="gmail_quote gmail_msg" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><u class="gmail_msg"></u>
