Web13.2 Total Store Order (TSO) However, the non-SC execution shows up on x86 machines, whose memory model is TSO. As TSO relaxes the write-to-read order, we attempt to write a TSO model tso-00.cat, by simply removing write-to-read pairs from the acyclicity check: "A first attempt for TSO" include "cos.cat" (* Communication relations that order … WebApr 14, 2024 · The TSO memory model allows strictly more behaviors than the classic SC memory model: writes are first stored in a thread-local buffer and non-deterministically flushed into the shared memory at a later time (also, the write buffers are accessed first when reading a shared variable).
