Overlapping split-phase large latency operations with computations is a standard technique for improving performance on modern architectures. In this paper, we present a general interprocedural technique for overlapping such accesses with computation. We have developed an Interprocedural Balanced Code Placement (IBCP) framework, which performs analysis on arbitrary recursive procedures and arbitrary control flow and replaces synchronous operations with a balanced pair of asynchronous operations. We have evaluated this scheme in the context of overlapping I/O operations with computation. We demonstrate how this analysis is useful for applications which perform frequent and large accesses to disks, including applications which snapshot or checkpoint their computations or out-of-core applications
