Buffer dimensioning for throughput improvement of dynamic dataflow signal processing applications on multi-core platforms

Marco Mattavelli, Malgorzata Maria Michalska, Simone Casale Brunet, Endri Bezati

Executing a dataflow program on a parallel platform requires assigning to each buffer a given size so that correct program executions take place without introducing any deadlock. Furthermore, in the case of dynamic dataflow programs, specific buffer size a ...

Trace-based manycore partitioning of stream-processing applications

Marco Mattavelli, Simone Casale Brunet, Endri Bezati, Malgorzata Maria Michalska

Application performance on these processor array platforms is highly sensitive to how functionality is physically placed on the device, as this choice crucially determines communication latencies and congestion patterns of the on-chip inter-core communicat ...
