[Barrelfish-users] Barrelfish Hello world on SCC

Hi Nil,

I assume you modified your menu.lst to start the hello program. The 
menu.lst [1] for the SCC provided in the tip version of the Barrelfish 
tree should not start the hello world program automatically.

Adding the following entry to the menu.lst would start the hello program 
on core 0 (assuming you compiled it).
module  /scc/sbin/examples/xmpl-hello core=0

If you wanted it to start on more cores, you could add several lines, 
such as:
module  /scc/sbin/examples/xmpl-hello core=0
module  /scc/sbin/examples/xmpl-hello core=1
module  /scc/sbin/examples/xmpl-hello core=2

If you omit the paramter core=, the program is started on the core 0.

Hope this helps,
