Recent GPUs are equipped with general-purpose L1 and L2 caches in an attempt to reduce memory bandwidth demand and improve the performance of some irregular GPGPU applications. However, due to the massive multithreading, GPGPU caches suffer from severe resource contention and low data-sharing which may degrade the performance instead. In this work, we propose three techniques to efficiently utilize and improve the performance of GPGPU caches. The first technique aims to dynamically detect and… CONTINUE READING
