在fedora.unix-center.net上的实验结果,加速比基本上约等于2。 -bash-3.2$gcc –xopenmp –o 2 2.c -bash-3.2$ ./2 the whole processing time of the program is 0.951687 seconds pi=3.141593 -bash-3.2$gcc –o 1 1.c -bash-3.2$ ./1 the whole processing time of the program is 1.791129 seconds pi=3.141593 同样的程序运行在t10000.unix-center.net上,效果完全不一样,具体原因还在寻找中。 -bash-3.00$ CC -o 11 1...

某宝上Raspberry pi 512m的都要卖240+上,国内的什么盒子的都在299左右,而cpu则是4核,内存1g神马的?有没有人直接拿各种盒子来做开发板的? {:2_172:} 跟pi比有优势么?
