An Adaptive Zero-Copy Strategy for Ubiquitous High Performance Computing

Using a heterogeneous platform has became a common approach to improve performance. This trend leads to critical problems of synchronization and superfluous memory copy construct, thus a memory model can be built to overcome this performance bottleneck via data exchange. Consequently, keeping the benefits of service consolidation while not losing performance and IO efficiency has become a crucial issue. In this paper, we present an adaptive strategy to solve the issue above in an efficient way. We first identify the critical overheads on Linux and and then presents a clever software zero-copy strategy to construct a prototype. Finally, we can optimize the work and leverage the hardware features to reduce the overhead of data copy. The result shows that the proposed prototype is an adaptive approach to perform service consolidation.
