OpenCL time excetion increase in time

hterrolle over 3 years ago

hi,

Sorry for the tittle, i do not know if is a coorect english ;))

I am testing on Hauwei Honnor play Kirim 970 and ARM mali G72 MP12. And use the 32 bit lib. 64 not working ?

So i found out that kernel time excecution increase in time. here are some output.

2021-08-18 13:58:43.877 E/JNIProcessor: 13 traitement bufligne finished in 49 ms temps Moy 49 Nb Frame 24

2021-08-18 13:58:46.169 E/JNIProcessor: 13 traitement bufligne finished in 86 ms temps Moy 90 Nb Frame 50

2021-08-18 13:58:51.611 E/JNIProcessor: 13 traitement bufligne finished in 109 ms temps Moy 109 Nb Frame 100

2021-08-18 13:58:57.534 E/JNIProcessor: 13 traitement bufligne finished in 112 ms temps Moy 115 Nb Frame 150

then the time stabalize around 100 Ms

here is one full frame traitment :

so i am wondering if i am doing some thing wrong using OpenCL. Or i may forgot an importante thing.

Thanks for the help.

regards herve terrolle

Hi! This might be caused by dynamic frequency and voltage adjustment.

You can find some info about in our guide ('Check system settings' section):

This can be applied to OpenCL as well.
