High-performance reconfigurable computers (HPRCs) provide a mix of standard processors and FPGAs to collectively accelerate applications. This introduces new design challenges, such as the need for portable programming models across HPRCs and system-level verification tools. To address the need for cosimulating a complete heterogeneous application using both software and hardware in an HPRC, we have created a tool called the Message-passing Simulation Framework (MSF). We have used it to simulate and develop an interface enabling an MPI-based approach to exchange data between X86 processors and hardware engines inside FPGAs. The MSF can also be used as an application development tool that enables multiple FPGAs in simulation to exchange messages amongst themselves and with X86 processors. As an example, we simulate a LINPACK benchmark hardware core using an Intel-FSB-Xilinx-FPGA platform to quickly prototype the hardware, to test the communications. and to verify the benchmark results.

In this paper, a new approach is being proposed to achieve mutual exclusion in distributed system using computer network and topology of nth nodes. In this executive approach nodes communicate among themselves using message passing technique. In this executive approach, distributed system with n nodes is logically partitioned into number of sub distributed system having only m½ nodes, where m is obtained by adding a minimum number in n to make it next perfect square number only if n is not a perfect square. Proposed algorithm is a Token based approach and achieves token optimally in 2 messages only for the best case and in worst case a node achieves token in n messages only.
