The growing capacity of integration allows to instantiate hundreds of soft-core processors in a single FPGA to create a reconfigurable multiprocessing system. Lately, FPGAs have been proven to give a higher energy efficiency than alternative platforms like CPUs and GPGPUs for certain workloads and are increasingly used in datacenters. In this paper we investigate whether many-soft-core processo...

In this paper we present MCoreSim, an open-source simulation framework for massively parallel and many-core computing systems based on OMNeT++. The simulator supports tile-based architectures with distributed memory and meshbased interconnects. Its primary purpose is to allow for investigations on the impact of the heterogeneous in-chip communication latencies, as arising due to the network-on-...

Processors with multiple (or many) cores and shared memory are becoming ubiquitous across the computing spectrum. MPI, the current de facto programming model for scalable parallel applications, enforces copies between source and target processes and thus can not fully utilize shared memory and cache architectures of modern machines. To enable MPI-based programs to more fully exploit features of...

This paper presents a parallel search parallel move approach to parallelise neighbourhood search algorithms on many-core platforms. In this approach, a large number of searches are run concurrently and coordinated periodically. Iteratively, each search generates and evaluates multiple moves in parallel. The proposed approach can fully utilise the computing capability of many-core platforms unde...

With the emergence of many-core processor architectures onto the HPC scene, concerns arise regarding the performance and productivity of numerous existing parallel-programming tools, models, and languages. As these devices begin augmenting conventional distributed cluster systems in an evolving age of heterogeneous supercomputing, proper evaluation and profiling of many-core processors must occ...

With the evolution toward fast networks of many-core processors, the design assumptions at the basis of software-level distributed shared memory (DSM) systems change considerably. But efficient DSMs are needed because they can significantly simplify the implementation of complex distributed algorithms. This paper discusses implications of the many-core evolution and derives a set of reusable el...
