struct AtomicMemoryCellClocks {

    write_vector: VClock,
    sync_vector: VClock,
    size: Size,
}
Expand description

Externally stored memory cell clocks explicitly to reduce memory usage for the common case where no atomic operations exists on the memory cell.

Fields§

§read_vector: VClock

The clock-vector of the timestamp of the last atomic read operation performed by each thread. This detects potential data-races between atomic read and non-atomic write operations.

§write_vector: VClock

The clock-vector of the timestamp of the last atomic write operation performed by each thread. This detects potential data-races between atomic write and non-atomic read or write operations.

§sync_vector: VClock

Synchronization vector for acquire-release semantics contains the vector of timestamps that will happen-before a thread if an acquire-load is performed on the data.

§size: Size

The size of accesses to this atomic location. We use this to detect non-synchronized mixed-size accesses. Since all accesses must be aligned to their size, this is sufficient to detect imperfectly overlapping accesses.
