We have developed and evaluated Argus-G, an error detection scheme for general purpose GPU (GPGPU) cores. Argus-G is a natural extension of the Argus error detection scheme for CPU cores, and we demonstrate how to modify Argus such that it is compatible with GPGPU cores. Using an RTL prototype, we experimentally show that Argus-G can detect the vast majority of injected errors at relatively low performance,...
Eliminating the conflict misses always remained the primary objective for the designers of cache memory. Although many alternative cache block placement techniques have been proposed in the past, the amount of research published on this so far is less than one expects. Most of the past techniques discuss to eliminate conflicts where an application generates a particular memory access pattern in a...
Eliminating the conflict misses in the caches has been a foremost field of research in cache memories. Although several cache addressing/indexing techniques have been demonstrated, most of them discuss about eliminating conflict misses for various memory access strides in a solo cache system. In this paper we present the analysis of the scenarios where conflicts arise at different levels of caches...
High-Performance Computing (HPC) in the cloud has reached the mainstream and is currently a hot topic in the research community and the industry. The attractiveness of cloud for HPC is the capability to run large applications on powerful, scalable hardware without needing to actually own or maintain this hardware. In this paper, we conduct a detailed comparison of HPC applications running on three...
Clouds enable novel execution modes often supported by advanced capabilities such as autonomic schedulers. These capabilities are predicated upon an accurate estimation and calculation of runtimes on a given infrastructure. Using a well understood high-performance computing workload, we find strong fluctuations from the mean performance on EC2 and Eucalyptus-based cloud systems. Our analysis eliminates...
When creating software for a new power systems control or protection device, the use of auto-generated C code via MATLAB Simulink Real-Time Workshop and Embedded Coder toolboxes can be a sensible alternative to hand written C code. This approach offers the benefits of a simulation environment, platform independence and robust code. This paper briefly summarises recent experiences with this coding...
