Memory race recording is a key technology in deterministic multi-core replay.High hardware consumption

large log size and slow replay speed limited the application of previous memory race recording algorithms.This paper proposes a new efficient hardware memory race recording algorithm

which is implemented in chunks and logs the outcomes of memory races in a point-to-point approach.In this recording mechanism

memory race is presented in a new stricter indirect dependency

a chunk-based transitive reduction algorithm is introduced to reduce the number of memory races logged

a maximum timestamp approximation method is proposed to deal with those races evicted from cache.This new memory race recording algorithm can replay a program at production run speed

and log a smaller memory race log using smaller hardware than previous point-to-point approaches.
