Hi Simon,
first of all, thank you very much! I am now successfully running FT and CG!
The first patch solved the allocation problem, I am successfully running up
to 48 cores. However I tried for 64 cores and I get the following error
(for FT):
Size : 256x256x128
Iterations : 6
ERROR: bomp_benchmark_.24 in slab_alloc() ../lib/barrelfish/slab.c:100

However CG does not work, I am getting the following error:

please advice,
thanks for you great help,
Antonio
