Short Introduction to DAPPLE programming

Prerequisites:

This introduction assumes that you already understand C++ and the concepts behind data-parallel computing. Thus, it is only intended to tell you about programming with DAPPLE.

This introduction is a short version that does not cover all of the DAPPLE features. Some may prefer the full-length introduction.

The basic idea of DAPPLE is to provide C++ classes that represent collections of data, and then some parallel operators and methods that can be applied to the collections. DAPPLE takes its inspiration from C*, NESL, and FORTRAN90.

• Vectors and Matrices, the core of DAPPLE
• Elementwise operations
• Vector-vector multiply
• Virtual processors
• Context and ifp()
• Reductions
• Moving data
• Input and output
• Details: unintuitive behavior
• Know what you're missing
• Quick reference: Vector operations
• Quick reference: Matrix operations
• Lots of example programs
