Subject: question about tasks, multithreading and multi-cpu machines

Message-ID: <dv6qsd$lg0$00$1@news.t-online.com> (raw)

In Ada it is possible to declare multiple parallel running "tasks". But for 
my opinion the keyword "task" is somewhat misleding because in fact, those 
"tasks" are really threads.

If I run such a program on a multi-cpu machine, the process itself will use 
only one cpu, even though I create several "tasks".

I tested this with gnat v3.15p under HPUX 11 on a multi-cpu server.

How can I write my code to utilize all cpu's on such a machine? Is there a 
different way in Ada to perform multi-tasking instead of multi-threading?

Thank you for your help!

Best regards, Norbert
