    Parallel Development: Parallel development methodology attempts to address the problem of long delays between the analysis phase and the delivery of the system. Instead of doing design and implementation in sequence, it performs a general design for the whole system and then divides the project into a series of distinct subprojects that can be designed and implemented .

Abstract: A finite element method is presented to compute time harmonic microwave fields in three dimensional configurations. Nodal-based finite elements have been coupled with an absorbing boundary condition to solve open boundary problems. This paper describes how the modeling of large devices has been made possible using parallel computation.

Chapter 4 Exploiting Instruction Level Parallelism with Software Approaches Notice that to schedule the delayed branch, the compiler had to determine that it could swap the DADDUI and S.D by changing the address to which the S.D stored: the address was 0(R1) and is now 8(R1).

This change is not trivial, since most compilers would see that. Exposing and exploiting structure: optimal code generation for high-order finite element methods MIKLÓS HOMOLYA, Imperial College London, UK ROBERT C.
