| description | This paper will present the implementation of parallel block factorization QR with Compact WY form. The parallel program has written in the SPMD (Single Program Multiple Data) style and use MPI (Message Passing Interface) library for communication. The program was successfully run in distributed memory system, with four computers. The Speedup was increase significantly long with increasing the number of processor and increasing the size of matrix: 1.47 for two processors, 1.84 for three processors and 2.13 for four processors. Abstract in Bahasa Indonesia : Dalam tulisan ini akan dipaparkan implementasi dari paralel Blok Faktorisasi QR dengan bentuk Compact WY. Program paralel ditulis dalam model SPMD (Single Program Multiple Data) dan memanfaatkan pustaka MPI (Message Passing Interface) untuk komunikasi. Program ini sukses dijalankan dalam sistem memori tersebar, dengan empat komputer. Terjadi peningkatan kinerja (speedup) yang berarti seiring dengan penambahan jumlah prosesor dan penambahan ukuran matriks: 1.47 untuk dua prosesor, 1.84 untuk tiga prosesor dan 2.13 untuk empat prosesor. |
