I don't know if I'm adding to the noise or signal but there is a definite solution to this problem: Put your C data in Arrays of 64 byte Structs. Java is ok too if you want object oriented atomic joint parallelism, but I only recommend using it on the server where you need a VM anyhow. C from 1970 and Java from 1990 still got things right. Also Vulkan/Metal/DX12 does not really help, OpenGL 3 with VAO is enough.
