[Barrelfish-users] Boot Barelfish on SCC with uncontinuous core sequence

[Stefan Kästle]

Hi,

first of all: which version of Barrelfish are you running on?
The current release is known to be broken on the SCC. Can you try 
release2012-11-03 instead?

Much of the Barrelfish code assumes the cores to be continuous. Thus, we 
just rename them internally to have a continuous representation, in case 
the core IDs as given by hardware are not. You can see that in your 
output in the following line:
> 1370610089.268328279 [tty0] spawnd.0: coreid 1 is arch id 4
Can you try using module /scc/sbin/test core=0 1 instead of 0 4 in your 
menu.lst to see if that helps?

Cheers,
  Stefan
