The coming of giga-bit networks makes possible the realization of a single nationwide virtual computer comprised of a variety of geographically distributed high-performance machines and workstations. To realize the potential that the physical infrastructure provides, software must be developed that is easy to use, supports a large degree of parallelism in the application code, and manages the complexity...
To address the separation between the hardware and software domains, this paper presents an abstract hardware/software model employing unified representation. The model supports early hardware/software evaluation and trade-off exploration. In addition, systems can be evaluated at different levels of detail, allowing those aspects of interest to be focused on. The benefits of a unified representation...
As microprocessor speeds increase, memory bandwidth is rapidly becoming the performance bottleneck in the execution of vector-like algorithms. Although caching provides adequate performance for many problems, caching alone is an insufficient solution for vector applications with poor temporal and spatial locality. Moreover, the nature of memories themselves has changed. Current DRAM components should...
An examination of the relation between architecture and compiler design leads to several principles which can simplify compilers and improve the object code they produce.
