Analysis of GPGPU Programs for Data-Race and Barrier Divergence
Analysis of GPGPU Programs for Data-race and Barrier Divergence Santonu Sarkar1, Prateek Kandelwal2, Soumyadip Bandyopadhyay3 and Holger Giese3 1ABB Corporate Research, India 2MathWorks, India 3Hasso Plattner Institute fur¨ Digital Engineering gGmbH, Germany Keywords: Verification, SMT Solver, CUDA, GPGPU, Data Races, Barrier Divergence. Abstract: Todays business and scientific applications have a high computing demand due to the increasing data size and the demand for responsiveness. Many such applications have a high degree of parallelism and GPGPUs emerge as a fit candidate for the demand. GPGPUs can offer an extremely high degree of data parallelism owing to its architecture that has many computing cores. However, unless the programs written to exploit the architecture are correct, the potential gain in performance cannot be achieved. In this paper, we focus on the two important properties of the programs written for GPGPUs, namely i) the data-race conditions and ii) the barrier divergence. We present a technique to identify the existence of these properties in a CUDA program using a static property verification method. The proposed approach can be utilized in tandem with normal application development process to help the programmer to remove the bugs that can have an impact on the performance and improve the safety of a CUDA program. 1 INTRODUCTION ans that the program will never end-up in an errone- ous state, or will never stop functioning in an arbitrary With the order of magnitude increase in computing manner, is a well-known and critical property that an demand in the business and scientific applications, de- operational system should exhibit (Lamport, 1977). -

CENTRAL PROCESSING UNIT . he CPU (central processing unit) is the heart of every embedded system and every personal computer. It comprises the ALU (arithmetic logic unit), responsible for the number crunching, and the CU (control unit), responsible for instruction sequencing and branching. Modern microprocessors and microcontrollers provide on a single chip the CPU and a varying degree of additional components, such as counters, timing coprocessors, watchdogs, SRAM (static RAM), and Flash-ROM (electrically erasable ROM). Hardware can be described on several different levels, from low-level tran- sistor-level to high-level hardware description languages (HDLs). The so- called register-transfer level is somewhat in-between, describing CPU compo- nents and their interaction on a relatively high level. We will use this level in this chapter to introduce gradually more complex components, which we will then use to construct a complete CPU. With the simulation system Retro [Chansavat Bräunl 1999], [Bräunl 2000], we will be able to actually program, run, and test our CPUs. -

MT-088: Analog Switches and Multiplexers Basics
MT-088 TUTORIAL Analog Switches and Multiplexers Basics INTRODUCTION Solid-state analog switches and multiplexers have become an essential component in the design of electronic systems which require the ability to control and select a specified transmission path for an analog signal. These devices are used in a wide variety of applications including multi- channel data acquisition systems, process control, instrumentation, video systems, etc. Switches and multiplexers of the late 1960s were designed with discrete MOSFET devices and were manufactured in small PC boards or modules. With the development of CMOS processes (yielding good PMOS and NMOS transistors on the same substrate), switches and multiplexers rapidly gravitated to integrated circuit form in the mid-1970s, with product introductions such as the Analog Devices' popular AD7500-series (introduced in 1973). A dielectrically-isolated family of these parts introduced in 1976 allowed input overvoltages of ± 25 V (beyond the supply rails) and was insensitive to latch-up. These early CMOS switches and multiplexers were typically designed to handle signal levels up to ±10 V while operating on ±15-V supplies. In 1979, Analog Devices introduced the popular ADG200-series of switches and multiplexers, and in 1988 the ADG201-series was introduced which was fabricated on a proprietary linear-compatible CMOS process (LC2MOS). These devices allowed input signals to ±15 V when operating on ±15-V supplies. A large number of switches and multiplexers were introduced in the 1980s and 1990s, with the trend toward lower on-resistance, faster switching, lower supply voltages, lower cost, lower power, and smaller surface-mount packages. Today, analog switches and multiplexers are available in a wide variety of configurations, options, etc., to suit nearly all applications. -
