Given a sufficient number of processors, the latency of the original non linear pipeline is three filters. The latency is the time it takes a token to flow from the beginning to the end of the pipeline.

Computer organization and architecture pipelining set. A static pipeline has only one functional configuration at a time. In order to examine the relation between the execution time of the rowcyclic algorithm and the block size, we ran the rowcyclic algorithm of two versions of gaussian elimination for different block sizes such as b s 1, 2, 4, 8, 16, 32, 64 on a multicore.
