The kernel code is:
__kernel void src_MyKernel(__global float *out, __global const float *in)
{
int index = get_global_linear_id();
float dummy;
out[index] = fract(in[index], &dummy);
}
I have used RGA shipped with RadeonDeveloperToolSuite-2022-08-01-115. Application version: 2.6.2.38 (07/25/2022).
I am running this on Ubuntu 20.04 Linux.
This kernel runs fine on my machine. Offline analysis with RGA fails. I suspect the OpenCL libraries shipped with RGA are obsolete.
The text was updated successfully, but these errors were encountered:
RGA 2.7 resolves the fract() issue. Thank you for fixing the problem.
But now the analysis result is much different from what I got with RGA 2.6.2.38
For a larger kernel, with asic gfx906 I got:
VGPRs: 63 / 256 | SGPRs: 50 / 102 with RGA 2.6.2.38
VGPRs: 83 / 256 | SGPRs: 48 / 102 with RGA 2.7.0.117
The build settings were identical in both versions (basically all default or empty except for the target GPU, which I set to gfx906)
And the code size of the binary became larger with the new version.
Honestly speaking, compilation results of RGA 2.6.2.38 look better to me.
If I try to compile an OpenCL kernel that calls the fract() function, I get the following error:
ld.lld: error: undefined hidden symbol: fract(float, float AS0*)
The kernel code is:
__kernel void src_MyKernel(__global float *out, __global const float *in)
{
int index = get_global_linear_id();
float dummy;
}
