Hello, help me figure it out. In the textbook there is a formula T = S + q * N,
where T is the time to complete the operation, S is the time to prepare the pipeline, q is the time to get the result on the pipeline, N is the length of the vector. It turns out that the operation on parts of the vector is performed not in parallel, but in series. What is included in this time q?

    Answer : Yes, sequentially, but in blocks

    Wikipedia is explained very accessible.

    • That is, if in a vector register vectors are 100 meters long and the length of the pipeline is 10, then it will divide the vector into blocks of 10 components and fold them sequentially? Then k will be equal to the ratio of time per block to the number of components in the block? - Wanti
    • @Wanti yes, you are right. - James Akwuh
