They also executed the entire DAG query plan as one simple operation,” said a KAIST official.FuseME can handle computation by fusing all, including matrix multiplication.The team came up with a method of determining which operations can improve AI performance and grouping them based on cost.It developed the technology for FuseME that can generate optimal performance by considering the properties of each group, network communication speed and input data size.By Hae-Sung Leeihs@hankyung.comJongwoo Cheon edited this article.
