This paper describes how aggressive loop unrolling is done in a retargetable optimizing compiler.

Since the most aggressive type of optimization a program can be subjected to is parallelization, understanding a program before attempting to parallelize it is a very important step.

However, aggressive compiler techniques such as loop unrolling, promoting of subscripted array variables into registers (especially in of subscripted array variables into registers (especially in loops) and interprocedural optimizations create heavy register pressure and it is still quite important to do a good job of register allocation.

The Itanium processor is an example of an Explicitly Parallel Instruction Computing (EPIC) architecture and thus relies on aggressive and expensive compiler optimizations for performance.

This sensibly eases the programmer task and allows for more aggressive optimisations of the global program structure.

The CUDA C code for the GPU, as well as the C and inline assembly code for the CPU, were highly optimized and aggressive compiler optimizations (-O4) were turned on.

Adjective

(en adjective)

Manifesting, exercising, or favoring rigour; allowing no abatement or mitigation; scrupulously accurate; exact; strict; severe; relentless; as, a rigorous officer of justice; a rigorous execution of law; a rigorous definition or demonstration.

, title= Boundary problems , passage=Economics is a messy discipline: too fluid to be a science, too rigorous to be an art. Perhaps it is fitting that economists’ most-used metric, gross domestic product (GDP), is a tangle too. GDP measures the total value of output in an economic territory. Its apparent simplicity explains why it is scrutinised down to tenths of a percentage point every month.}}

Severe; intense; inclement; as, a rigorous winter.

Violent.
