“…Meanwhile, computation behaviors are often overlooked. Computation behaviors are more diverse and difficult to trace, so they are usually recorded as time intervals and replayed by calling sleep functions or empty loops [13,15,24,31,34,43]. Besides, lossy compression methods are used to further reduce the storage cost of communication trace, of which the original communication parameters and timing information are approximated by histogram [23,34,36], clustering [2,3], and stochastic process [8,15,31].…”
