N+2 is pitched memory copy. I need to read the globalBorders, currently commented out. Uold += index; this really improves the performance. I need to reorder and unloop my code. The performance right now is around 38 Gflops for double. I should do better. text/html 2009-11-20T09:05:01-08:00 Didem Unat http://ege.ucsd.edu/dokuwiki-2009-02-14/doku.php?id=didem:conference:sc09&rev=1258736701&do=diff Power Puzzle Panel * System architecture * FTT and graph isomerism * their kernel Thomas Sterling * not steam processor but minimum latency, high bandwidth, simple architecture = hete is there.
