C vs Python. Hector, 1 node SMP, 1-24 cores

Speedups:

Topographica:


C-Topo:



Parallel Efficiencies:


                Topographica  C-Topo
cpu_cores: 1    E = 99.0%     E = 99.5%
cpu_cores: 2    E = 95.4%     E = 98.3%
cpu_cores: 4    E = 89.3%     E = 96.3%
cpu_cores: 8    E = 78.4%     E = 91.7%
cpu_cores: 16   E = 66.1%     E = 90.6%
cpu_cores: 24   E = 55.4%     E = 86.2%

    This is good, the parallel problem for Topographica is displayed and you can work towards re-creating it in C or addressing it in Topographica.

    cheers
