A Fast and Generic GPU-Based Parallel Reduction Implementation

Reduction operations are extensively employed in many computational problems. A reduction consists of, given a finite set of numeric elements, combining into a single value all elements in that set, using for this a combiner function. A parallel reduction, in turn, is the reduction operation concurrently performed when multiple execution units are available. The current […]

Parallel Computing for the Inverse of SPD matrix

In this paper, we propose a High performance Parallel Computing method for the Inverse of a symmetric positive definite (SPD) matrix. Brought in the reuse of the inverse of diagonal sub blocks technique and Combined with the newest OpenCL parallel computing framework, this methods can improve computing the inverse of SPD matrix effectively. Computing the […]

Architecting SOT-RAM Based GPU Register File

With increase in GPU register file (RF) size, its power consumption has also increased. Since RF exists at the highest level in cache hierarchy, designing it with memories with high write latency/energy (e.g., spin transfer torque RAM) can lead to large energy loss. In this paper, we present an spin orbit torque RAM (SOT-RAM) based […]

The Sixth International Workshop on Power-Efficient GPU and Many-core Computing (PEGPUM), 2018

The recent success of advanced mobile platforms coincides with the rising challenge of ensuring a long battery life, and accompanies a larger trend away from increasing processor clock speeds in favor of increasing parallelism. That high performance computing (HPC) is also strongly motivated in this area, as witnessed by the recent Green500 List project, illustrates […]

Parallel Matching and Clustering Algorithms on GPUs

The main focus of this thesis is on developing efficient algorithms on GPUs for certain matching and clustering problems. Through extensive experiments we show that sparse and unstructured problems can benefit greatly from using GPUs as long as the algorithms are carefully designed. Even though none of the presented algorithms are fundamentally new, they still […]
