【讨论】买了Intel Edison开发板,在处理器上觉得Intel吹牛了 打算做一个嵌入式服务器 买了Intel Edison是因为它有arduino base board扩展板,不仅可以用arduino IDE编程还可以直插arduino的各种shield 因为装有Linux系统,于是买回来用Intel那里下载的Intel Optimized LINPACK Benchmark程序跑了跑分,数据如下: Sat Jan 31 10:58:34 UTC 2015 Intel(R) Optimized LINPACK Benchmark data Current date/time: Sat Jan 31 10:58:35 2015 CPU frequency: 0.460 GHz Number of CPUs: 1 Number of cores: 2 Number of threads: 2 Parameters are set to: Number of tests: 9 Number of equations to solve (problem size) : 15000 14000 13000 12000 11000 10000 8000 6000 1000 Leading dimension of array : 15000 14008 13000 12008 11000 10008 8008 6008 1000 Number of trials to run : 1 2 2 2 2 2 2 3 4 Data alignment value (in Kbytes): 4 4 4 4 4 4 4 4 4 Maximum memory requested that can be used=800844256, at the size=10000 =================== Timing linear equation system solver =================== Size LDA Align.
