Description

technical field

[0001] The invention relates to the field of high-performance computing, in particular to a device for capturing memory access information in real time and a method for capturing memory access information. Background technique

[0002] Tracing and acquisition (profiling) of memory access information is traditionally used for program compilation and optimization to improve program performance. At the same time, in the research and implementation of high-performance computers, remote distributed storage is an important way, especially the use of optical interconnection, which can pull the local memory to the remote end and realize the loose coupling of memory and processor. In order to hide remote memory latency, prefetching is an important and effective way, but an efficient prefetching strategy requires an understanding of memory access patterns as a basis.

[0003] Existing memory access information capture and tracking (profiling) methods can be classified...
