In this paper, we design and evaluate a remote memory disk cache (RMDC) for high-performance disk I/O. For this purpose, we propose the Remote Memory Block Device (RMBD) that abstracts a set of remote memory regions into a local block device. The RMBD can be used as a cache device for any block devices as well as a stand-alone block device. We evaluate the RMDC using standard benchmarks such as TPC-C,...
Hyperspectral imaging is a new technique in remote sensing that generates images with hundreds of spectral bands, at different wavelength channels, for the same area on the surface of the Earth. The price paid for such a wealth of spectral information is the enormous amounts of data to be processed. In recent years, several efforts have been directed towards the incorporation of high-performance computing...
Heterogeneous systems provide new opportunities to increase the performance of parallel applications on clusters with CPU and GPU architectures. Currently, applications that utilize GPU devices run their device-executable code on local devices in their respective hosting-nodes. This paper presents a package for running OpenMP, C++ and unmodified OpenCL applications on clusters with many GPU devices...
On today's commodity clusters, achieving near-optimal speedup is very hard. We have previously shown that parallel applications using synchronous sequential MPI calls can be optimized by runtime replacement with corresponding asynchronous MPI operations. This may be achieved by protecting memory used by the MPI call from application writes until the operation is complete. However, changing the protection...
