摘要

在concurrent Haskell中，使用一种带进程和未来的按需调用函数语言实现了软件事务内存的并发实现。小步骤操作语义的描述是精确和显式的，并采用了冲突事务的早期中止。对于具有可能和应该收敛性的上下文语义，给出了实现正确性的证明。这意味着我们的实现对于带有大步骤语义的抽象规范来说是一个正确的求值器。

Correctness of an STM Haskell implementation

A concurrent implementation of software transactional memory in Concurrent Haskell using a call-by-need functional language with processes and futures is given. The description of the small-step operational semantics is precise and explicit, and employs an early abort of conflicting transactions. A proof of correctness of the implementation is given for a contextual semantics with may- and should-convergence. This implies that our implementation is a correct evaluator for an abstract specification equipped with a big-step semantics.
