judging vulkan barriers explained , seems each vkcmdpipelinebarrier introduces dependency between 2 subsequent pipeline “runs”. typical scenario of shader writes image , shader b samples same image, might this: dispatch shader writes image a vkcmdpipelinebarrier(cmd, vk_pipeline_stage_color_attachment_output_bit, vk_pipeline_stage_fragment_shader_bit, ...); dispatch shader reads image a this defines dependency first shader execution's color attachment stage second shader execution's fragment stage. if want run independent commands in between? example dispatch shader writes image a dispatch unrelated shader doesn't touch image a vkcmdpipelinebarrier(cmd, vk_pipeline_stage_color_attachment_output_bit, vk_pipeline_stage_fragment_shader_bit, ...); dispatch shader reads image a this still works, inefficient: because fragment shader stage has wait color attachment output stage of previous, unrelated shader. how specify dependency on shader before it? ...
