Working on Scaling runs on bluehive's infiniband nodes and example of load balancing across threads

Currently running two sets of scaling tests. All simulations are 2D

Weak scaling

filling fraction .25
MaxLevel 0,1,2,3,4
Threaded/Every Level Balanced N/Y, Y/N, Y/Y
nProcs 1 2 4 8 16 32 48 64 80 96 104 112
Base Res1 (per processor) 64 128 5122
  • 1 Domains are kept square with number of cells per processor approximately constant
  • 2 Only with a MaxLevel of 3

Strong Scaling

filling fraction .1 .2 .3 .5 .7 1
MaxLevel 4
Threaded/Every Level Balanced N/Y, Y/N, Y/Y
nProcs 1 2 4 8 16 32 48 64 80 96 104 112
Base Res 32 64
