I think the file is from this webside http://www.eofw.org/bench/

Can't wait to see if the 8 threads ability was a proof of principle and can just be extended...and just spawn threads to the OS and have that take care of scheduling and resources.

i have try the latest Blender provided in the previous topic, support up to 8 cpu is great
i cannot resist to do some benchmark and i observe some strange behaviour in multithread
i use the same test scene between the Octane2 dual R12k and the O2k 8 R10k 250
the first try i do with the O2k was about 1m17s75.....slower than my Octane2.... ??
parametters was, 8 threads, render tile 4x4
at the begining of the rendering all the cpu are loaded, and gradualy as therendering progress, the used cpu number goes lowering. why ??
at the begining the rendering was very fast, and when the most rendering parts are done, the rendering brake seriousely
so i have found a solution, i adjuste the tile render zone as multiple of numbers of cpu, so this is the result with this mods:
8 threads, render tiles 8x8 done in 25s63...... awesome no ?
from to start to the end of the rendering, all the cpu are used....
regards & happy new year
