Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Current multiprocessor systems execute parallel and concurrent software nondeterministically: even when given precisely the same input, two executions of the same program may produce different output. This severely complicates debugging, testing, and automatic replication for fault-tolerance. Previous efforts to address this issue have focused primarily on record and replay, but making execution actually deterministic would address the problem at the root.#R##N##R##N#Our goals in this work are twofold: (1) to provide fully deterministic execution of arbitrary, unmodified, multithreaded programs as an OS service; and (2) to make all sources of intentional nondeterminism, such as network I/O, be explicit and controllable. To this end  propose a new OS abstraction, the Deterministic Process Group (DPG). All communication beten threads and processes internal to a DPG happens deterministically, including implicit communication via shared-memory accesses, as ll as communication via OS channels such as pipes, signals, and the filesystem. To deal with fundamentally nondeterministic external events, our abstraction includes the shim layer, a programmable interface that interposes on all interaction beten a DPG and the external world, making determinism useful even for reactive applications.#R##N##R##N# implemented the DPG abstraction as an extension to Linux and demonstrate its benefits with three use cases: plain deterministic execution; replicated execution; and record and replay by logging just external input.  evaluated our implementation on both parallel and reactive workloads, including Apache, Chromium, and PARSEC.
