A Comparison Of X86 Computer Architecture Simulators, Ayaz Akram, Lina Sawalha Oct 2016

A Comparison Of X86 Computer Architecture Simulators, Ayaz Akram, Lina Sawalha

Computer Architecture and Systems Research Laboratory (CASRL)

The significance of computer architecture simulators in advancing computer architecture research is widely acknowledged. Computer architects have developed numerous simulators in the past few decades and their number continues to rise. This paper explores different simulation techniques and surveys many simulators. Comparing simulators with each other and validating their correctness has been a challenging task. In this paper, we compare and contrast x86 simulators in terms of flexibility, level of details, user friendliness and simulation models. In addition, we measure the experimental error and compare the speed of four contemporary x86 simulators: gem5, Sniper, Multi2sim and PTLsim. We also discuss …

Gpu-Arraysort: A Parallel, In-Place Algorithm For Sorting Large Number Of Arrays, Muaaz Awan, Fahad Saeed Aug 2016

Gpu-Arraysort: A Parallel, In-Place Algorithm For Sorting Large Number Of Arrays, Muaaz Awan, Fahad Saeed

Parallel Computing and Data Science Lab Technical Reports

Modern day analytics deals with big datasets from diverse fields. For many application the data is in the form of an array which consists of large number of smaller arrays. Existing techniques focus on sorting a single large array and cannot be used for sorting large number of smaller arrays in an efficient manner. Currently no such algorithm is available which can sort such large number of arrays utilizing the massively parallel architecture of GPU devices. In this paper we present a highly scalable parallel algorithm, called GPU-ArraySort, for sorting large number of arrays using a GPU. Our algorithm performs …
