Charm++ parallel programming system

[Jozsef Bakosi <jbakosi AT lanl.gov>]

The command line is

$ mpirun -n 4 --bind-to none -oversubscribe 
/home/quinoa/quinoa/build/Main/inciter -c slot_cyl_cfl_diagcg.q -i 
unitsquare_01_3.6k.exo -v -l 10 -u 0.9 +balancer RandCentLB +LBDebug 1 +cs

The -u 0.9 means we do overdecomposition.

Thanks, Ronak
Jozsef
