memory access when using OpenCL without X11
However it's not only related to mclk and sclk. I tried this:
rocm-smi --setsclk 2
rocm-smi --setmclk 3

However it's not only related to mclk and sclk. I tried this:

IN the case when memory is slow, the rocm-smi outputs this:

I'd suspect a problem related to memory clock. This is an APU where
system memory is shared with the CPU, so if the SMU changes memory
clocks that would affect CPU memory access performance. If the problem
only occurs when OpenCL is running, then the compute power profile
Seems sysbench cpu test does not slow down:
1) run sysbench cpu on idle machine:
sysbench cpu run
...
General statistics:
total time: 10.0033s
total number of events: 19052
2) start ./cl_slow_test 1 1 in background
3) run sysbench again
sysbench cp

Even if it's using CPU for OCL (I know it's not doing this), why does
memcpy on CPU slow down permanently, if I'm not doing anything with OpenCL
after clCreateContext?
As you see from test program it just does clCreateContext and then a loop
of memcpy-s on CPU.
Also I found out that writing diffe
I think you are probably using the CPU for OCL in the remote login
case. When you log into the desktop, the permissions on the device
nodes get changed dynamically to support accelerated rendering. You
probably need to change the permissions on the device nodes manually
if you are not logging int
Hi!
I am using Ryzen 2400G with Gigabyte AMD B450 AORUS board. I have latest
bios, ubuntu 18.04 and latest mainline kernel (5.0.0-05-generic)
installed. Also I have rocm-dev 2.1.96 but no rock-dkms installed.
I found that when I log in over ssh and try to use OpenCL (doing
