Advantages and disadvantages of using the
pointer vector method in a vector dataflow processor
The article is devoted to the analysis of the quick
sort (QS) program execution in a vector
dataflow processor (VDP), which uses the pointer vectors
method to store arrays. The deficiency of pointer vectors
method revealed in the QS program is analyzed
and a method for solving this disadvantage is
proposed by introducing split and fuse commands into the processor
instruction set. Despite the significant
complication of the graph and increase the overall
number of commands executed in the QS program, the
introduction of new split and fuse commands
into VDP command system made it possible to achieve up to
11× faster performance than Intel Skylake processor core.
Moreover, the peak performance of the VDP and
Intel Skylake differ only by 8 times.
(in Russian).
Key words: vector processor, dataflow architecture, sorting
program, instruction level parallelism,
fine-grained parallelism, vector performance. |
