computeShader1DExecuteSize

Determines optimal size of ComputeShader execution for 1-dimensional data of variable size.

Note: if the data size is not dividable by the work group size, the excessive invocations will happen and must be discarded in the compute shader:

#version 430
layout (local_size_x = 64) in;

uniform int p_dataSize;

void main() {
    int x = int(gl_GlobalInvocationID.x);
    if (x >= p_dataSize) {
        return;
    }
    // shader code
}
