因为MASS向量函数要比对一个标准库函数的重复访问快很多(倍数接近30倍),所以最后得到的性能改善效果将会是惊人的。
Since the MASS vector functions are much faster (by a factor of up to about 30) than a repeated call to a standard library function, the resulting performance improvement can be substantial.
向量处理器系统的性能很高,在20世纪80年代到90年代早期一度在HPC体系架构中占有统治地位,但是最近几年以来,集群变得更加流行了。
Vector processor systems deliver high performance and were the dominant HPC architecture in the 1980s and early 1990s, but clusters have become far more popular in recent years.
另外也有用于 IBM PowerPC 970 处理器的 VMX 向量扩展,可以提高向量化代码的性能。
There are also VMX vector extensions for the IBM PowerPC 970 processor that can increase the performance of vectorized code.
