In such large applications as numerical simulations, these difficulties become more serious and dominant. One of approaches to overcome these difficulties is automatic program generation from high level problem description. In this paper, NSL, a new numerical simulation language for PDE problems, is proposed. NSL provides advanced features: flexible problem description function and automatic parallel processing. Its translator and parallel processing techniques are also described. The efficiency of the system is 87.6% for the grid generation part and 90.2% for the solver part in case that the number of grid points is 40000 and the number of PEs is 16.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/10312"}]},"item_10_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"情報処理学会","subitem_publisher_language":"ja"}]},"item_10_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"ここに掲載した著作物の利用に関する注意 本著作物の著作権は（社）情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします。 Notice for the use of this material The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
