目前,PC硬件在同时处理多项任务方面已经发展得越来越令人满意了。但是与此同时,能够使这种并行潜力得到充分发挥的商业运算软件却是廖廖无几。这种发展的不平衡状况使软件开发人员陷入了两难的境地。前一段在San Jose举行的微处理器论坛大会上,许多硬件厂商就如何为软件开发商在并行运算上提供更多的机会这一问题上发表了各自的观点。IBM公司的代表——Power4处理器内核的主要设计人Jim Kahle先生将大型数据库、随机
Currently, PC hardware has grown more and more satisfying in terms of handling multiple tasks simultaneously. But in the meantime, business computing software that can bring this parallelism to its fullest potential is inexhaustible. The imbalance in this development has left software developers in a dilemma. At a previous Microprocessor Forum in San Jose, many hardware vendors expressed their opinions on how software developers can provide more opportunities for parallel computing. Jim Kahle, IBM’s principal designer and chief architect for the Power4 processor core, put large databases randomly
