A MATLAB-Based Code Generator for Parallel Sparse Matrix Computations Utilizing PSBLAS SASAOKA, Taiji ササオカ, タイジ KAWABATA, Hideyuki カワバタ, ヒデユキ KITAMURA, Toshiaki キタムラ, トシアキ 笹岡, 泰司 川端, 英之 北村, 俊明 application/pdf Parallel programs for distributed memory machines are not easy to create and maintain, especially when they involve sparse matrix computations. In this paper, we propose a program translation system for generating parallel sparse matrix computation codes utilizing PSBLAS. The purpose of the development of the system is to offer the user a convenient way to construct parallel sparse code based on PSBLAS. The system is build up on the idea of bridging the gap between the easy-to-read program representations and highly-tuned parallel executables based on existing parallel sparse matrix computation libraries. The system accepts a MATLAB program with annotations and generates subroutines for an SPMD-style parallel program which runs on distributed-memory machines. Experimental results on parallel machines show that the prototype of our system can generate fairly efficient PSBLAS codes for simple applications such as CG and Bi-CGSTAB programs. journal article 電子情報通信学会(IEICE) 2007-01-01 VoR application/pdf IEICE Transactions on Information and Systems 1 E90-D 2 12 AA10826272 1745-1361(online)|0916-8532(print) https://hiroshima-cu.repo.nii.ac.jp/record/1314/files/e90-d_1_2.pdf https://hiroshima-cu.repo.nii.ac.jp/records/1314 eng http://www.ieice.org/jpn/trans_online/ http://www.ieice.org/jpn/trans_online/ copyright©2007 IEICE
