Multicore shared-memory multiprocessors now rule the desktop and server markets, and are poised to dominate embedded systems. Multicore shared-memory architectures are becoming prevalent and bring many programming challenges. Among the biggest are data races: accesses to shared resources that make a program's behavior depend on scheduling decisions beyond its control. To eliminate such races, the SHIM concurrent programming language adopts deterministic message passing as it sole communication mechanism. The authors demonstrate such language restrictions are practical by presenting a SHIM to C-plus-Pthreads compiler that can produce efficient code for shared-memory multiprocessors.
