By means of partial reconfiguration, parts of the hardware can be dynamically exchanged during operation what allows to adapt the system to changing requirements, and even enables the implementation of self-managing systems. This however requires sophisticated system architectures as well as proper algorithmic runtime support. In this paper, we present an algorithm for placing streaming applications...
MPI is the traditional paradigm to parallelize applications for High Performance Computing environments. AzequiaMPI is an implementation of the MPI-1.3 standard. Its thread-based architecture enables it to run on high-end HPC machines as well as on embedded environments as soft-core processor in FPGAs. This article describes the experience of building a maintainable cluster of fourteen popular Xilinx...
A hardware solver, implemented on an FPGA, for calculating the Page Rank eigenvector using the Power method is described. The critical operation is a very large sparse matrix by vector multiplication (SMVM). However, we show that the SMVM can be replaced with a pattern adder (a term coined to denote SMVM without multiplication), and a dense element by element vector multiplication, thus simplifying...
