Chapter 9 Objectives After you have read and studied this chapter you should be able to Manipulate a collection of data values using an array. Declare and use an array of primitive data types in writing a program. Declare and use an array of objects in writing a program. Describe how a two-dimensional array is implemented as an array of arrays. Manipulate a collection of objects using a vector. Use MultiInputBox object from the javabook package to input an array of strings

• Study increasingly sophisticated parallel merge kernels • Observe the combined effects of data - dependent execution and a lack of data parallelism on GPU algorithm design

• To learn to regularize irregular data with – Limiting variations with clamping – Sorting – Transposition • To learn to write a high-performance SpMV kernel based on JDS transposed format • To learn the key techniques for compacting input data in parallel sparse methods for reduced consumption of memory bandwidth – Better utilization of on-chip memory – Fewer bytes transferred to on-chip memory – Better utilization of global memory – Challenge: retaining regularity
