erlang start up log

ARUN P
Hi,

If I type erl on terminal I am getting a start up log as shown below

*12:42:09* ~$ erl
Erlang/OTP 17 [erts-6.3] [source-f9282c6] [smp:4:4] [async-threads:10] [hipe] [kernel-poll:false]

Eshell V6.3  (abort with ^G)
1>

Can somebody explain me, [smp:4:4] [async-threads:10] [hipe] [kernel-poll:false] what are these informations indicate.? And how to cross verify whether the symmetric multiprocessing(SMP) is enabled or not.?

Regards,
Arun P

Re: erlang start up log

Dmytro Lytovchenko
smp = symmetric multiprocessing, 4:4 = 4 cores, 4 schedulers started one per core. Yes SMP is strong in this one
async-threads 10 = for IO offloading, increase this number with command line options if your program does a lot of disk IO and you notice underperformance.
hipe = native compiler backend and JIT
kernel-poll = more efficient socket interface, if your program does a lot of networking, you might consider setting +K as command line option
