General-purpose graphics processing unit (GPGPU) has become one of the most important high performance platforms oriented to high throughput applications. However, on-chip resources contention can often occur as there are large amounts of concurrent running threads inside GPGPU. It has become an important factor affecting the performance of GPGPUs. We propose memory-aware TLP throttling and cache bypassing (MATB) mechanism, which can exploit data temporal locality and memory bandwidth. It aims to make those cache blocks with good data locality stay inside L1D cache longer while maintaining on-chip resources utiliza- tion. On one hand, it can alleviate cache contention via limiting the memory warps with bad data reuse to be scheduled while cache contention and on-chip network congestion occur. On the other hand, it can make memory bandwidth be utilized more effectively via cache bypassing. Experimental results show MATB can achieve 26.6% and 14.2% performance improvement respectively on average relative to GTO and DYNCTA with low hardware cost.
