Abstract:
|
The main goal of the AXIOM project is to design a small board that could be used as a LEGOTM-style module to build systems with more performance while keeping the programming task simple by using a familiar shared-memory programming model. The interconnection plays a crucial role both for the need of providing fast and reliable communication (including lossless control flow as, e.g., Infiniband, but with a simplified scope and cost). In this paper, we outline some of our initial choices and explore the performance of RDMA based mechanisms and interfaces, including the remote memory management behind the programming model. Our initial results show a potential for scaling the system as we use DF-Threads, good bandwidth for RDMA transfers, promising to scale once we use the OmpSs, programming model. |
