Programs used for the evaluation are written in the functional language DFC. Evaluation was done with automatic extraction of parallelism and automatic load distribution function. Sustained performance of floating point operations is 118 MFLOPS. This data shows that the SIGMA-1 can be comparable with existing vector supercomputers. Then the effect of data distribution between processors is measured. The results show that the feature of hiding latency of dataflow computers is not effective in case that programs have many communitations. As architecture evaluations, the effect of function call, loop construct were measured and compared with a current high speed workstation. Then the effect of automatic extraction of parallelism is analyzed, Utilization of matching memory is also discussed.","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/2237/10311"}]},"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).
