Transport Protocols for Large Bandwidth-Delay Product Networks - TCP Extensions and Alternative Transport Protocols

TCP's poor performance is identified as the bottleneck of high-speed networks. Extensions to TCP have been proposed and implemented. Some authors abandon TCP at all and suggest new transport protocols to overcome TCP limitations, at the expense of compatibility. This paper reports a research on the most significant TCP extensions and transport alternatives, and comparison between them. The majority of the solutions pointed out are difficult to compare because they are tailored to specific configurations. Still there is no specific criteria to evaluate performance metrics and comparison is done on the most evident issues.

Designing Hardware/Software Systems for Embedded High-Performance Computing

In this work, we propose an architecture and methodology to design hardware/software systems for high-performance embedded computing on FPGA. The hardware side is based on a many-core architecture whose design is generated automatically given a set of architectural parameters. Both the architecture and the methodology were evaluated running dense matrix multiplication and sparse matrix-vector multiplication on a ZYNQ-7020 FPGA platform. The results show that using a system-level design of the system avoids complex hardware design and still provides good performance results.
