PPT-A Case Against Small Data Types in GPGPUs

Ahmad Lashgar and Amirali Baniasadi ECE Department University of Victoria Evaluation of Datatype Size on GPGPUs Key Observation Smallest datatypes always improve memory efficiency. Data types, variable declaration, and initialization. Type. Size. Use. Int. 4 bytes. Integer. Long. 8 bytes. Bigger Integer. Float. 4 bytes. Decimal values. Double. 8 bytes. Precise. decimals.

The data is usually described as a certain type. This type determines what you can do with the data and how the data is stored. In Python basic types are integers (. int. ), floating point (float), strings and Booleans. Objectives. Work with numeric data. Describe the difference between value types and reference types. Declare and use variables to store data. Create constants. Write expressions containing arithmetic operators and operands. November 8, 2013. With Heather Gowdy, Senior Manager. Case Study: .

Organization made up of various departments, each having a name, identifying no., and an employee who is the manager. A department may be located in different places. Information about employee includes name, identification number, birth date, address, sex, and salary. Each employee is assigned to one department. The date the manager is appointed to a department is also tracked. Employees may be directly supervised by another employee. Each project within the organization is controlled by a department. Employees (not necessarily from the controlling dept.) are assigned to projects. Information about projects includes project name, no., and location. Hours spent by employees on each project are also kept.. COMPUTER SCI. DEPARTMENT. Introduction:. C . Programming is an ANSI/ISO standard and powerful programming language for developing real time applications. C programming language was invented by Dennis Ritchie at the Bell Laboratories in 1972. It was invented for implementing UNIX operating system. C is most widely used programming language even today. All other programming languages were derived directly or indirectly from C programming concepts. This tutorial explains all basic concepts in C like history of C language, data types, keywords, constants, variables, operators, expressions, control statements, array, pointer, string, library functions, structures and unions etc..
