One of the limitations of a compute is the memory bandwidth. For the scope of this article, I define “memory bandwidth” as the maximal number of bytes you can bring from memory to the CPU per unit of time. E.g., if your system has 5 GB/s of bandwidth, you can read up to 5 GB from memory in one second. To measure this memory bandwidth, I propose to read data sequentially. E.g., you may use a function where we sum the byte values in a large array. It is not necessary to sum every byte value, you c...
