I was able to push it better by another 10 sec with the DR setup when using 36 threads at a time.
$ numactl -N 0 ./vray -sceneFile=/home/user/Downloads/vrscene/myscene.vrscene -distributed=1 -renderHost=localhost -numThreads=36 -display=0
Frame took 84.64 sec (display=0) vs 95.04 sec (display =1)
It looks like the display doesn’t work as promised with more than 40 Threads.
I ran three times with ‘all threads’ on -display=0 with results of 138.30 sec, 141.20 sec and 141.96 sec.
I ran again -display=1 and I got 141.10 sec (yesterday 135.86). So basically it makes virtually no difference.
$ ./vray -sceneFile=/home/user/Downloads/vrscene/myscene.vrscene
Frame took 138.30 s, 141.20 s, 141.96 s
Any more ideas ?
