Andrea, GG says maybe it is something to do with permissions on the proc filesystem. Does it use only 1 cpu when you run a small test as "root" instead of an ordinary user? On Sat, Jun 27, 2020 at 2:00 AM Andrea paz <[email protected]> wrote:
Render farm is OK, now. Thanks.
I did some more rendering tests: CPU 8c/16t "use HW device" --> none Container: mp4 codec: h264
Default (none or threads=0) --> 86.5 fps
[note: does not vary by changing SMP (obviously); I tried SMP=4; 8 and 14 with the exact same result]
threads=8 --> 64.2 fps
threads=15 --> 72.8 fps (I read somewhere that ffmpeg handles up to 15 threads; I don't know if this is true)
threads=16 --> 73.2 fps
[Note: in all these tests, from Top you can see that the rendering starts from 1000 - 1200%, but then after about ten seconds, it goes to 400 - 600% until the end of the rendering.]
Render farm OK: all the cores at 100% --> 170 fps
When I compile CinGG, I use this "configure":
env CUDA_PATH=/opt/cuda ./configure --without-oss --with-cuda --with-single-user --with-booby
maybe I need to add/take out some flags? (e.g. --prefix=/usr) -- Cin mailing list [email protected] https://lists.cinelerra-gg.org/mailman/listinfo/cin
