Simple extensions of 1-writer atomic variable constructions to multiwriter ones
We present several simple wait-free constructions of multiwriter multireader multivalued atomic shared variables. These are extensions of two 1-writer constructions in the literature and use a multiwriter multireader fixed-valued atomic variable. All the constructions are intuitive, and their correctness proofs are short and easy to follow. Some constructions are conflict-free, that is, in each execution, no reading of a buffer overlaps with any writing of that buffer. All the conflict-free constructions have the property that there is only one reading of a buffer in a read execution. Some of them have the additional property that there is only one writing of a 1-reader buffer, for each reader, in a write execution.
