In our Video Analitics software, we are using Systems with Quadro P4000 GPU’s and others with only changing the GPU’s to RTX 5000 and RTX 4000.
The configurations are the following:
Common configuration
- SuperMicro H11SSL-i motherboard with EPYC 7401P processor.
- 64GB of RAM memory DDR4 (fully utilitzing the 8 channels).
- Windows 10 Pro Version 1809 Build 17763.379
- Driver version 419.67
GPU configuration based on Pascal:
- 3 Quadro P4000.
- 2 using TCC driver.
- 1 using WDDM driver for connecting to a display, and doing OpenGL.
GPU configuration based on Turing:
- 2 Quadro RTX5000, TCC driver, NVLink conected.
- 1 Quadro RTX4000, WDDM driver for connecting to a display, and doing OpenGL.
Only in the Turing based configuration, the system process named “System Interrupts” uses 100% of the CPU when executing our software, and it stays the same even if we close our software.
As this only happens with RTX, we understand it might have something to do with the driver version for RTX. It does not happen always, but happens many times.
We can’t provide our software without NDA. We did not do a toy example, since our aplication is very big, and an small example maight not reproduce the issue. So, the quiestion is, is this a known issue for this driver version? Or for any of the configurations we are using?
Thanks!
