As there are other processor measures such as size of a chip cache , speed of memory bus , and word width , there are at least three other noteworthy measures of beowulf performance 正如其它度量处理器的手段有芯片缓存的大小、内存总线的速度和字宽一样,至少有三种值得注意的度量beowulf性能的方法。
By combining the three lock - unlock pairs into a single lock - unlock pair , performance is improved by reducing instruction count and reducing the amount of synchronization traffic on the memory bus 把三个上锁-解锁对组合到一个上锁-解锁对,降低了指令数量和内存总线上同步流量的数量,从而提高了性能。
The memory bus is the computer bus which connects the main memory to the memory controller in computer systems. Originally, general-purpose buses like VMEbus and the S-100 bus were used, but to reduce latency, modern memory buses are designed to connect directly to DRAM chips, and thus are designed by chip standards bodies such as JEDEC.
