The Raspberry Pi costs around $70 (CPU board, case, power supply, SD card), weighs a few ounces, uses a 5 watt power supply and is more than 4.5 times faster than the Cray 1. It was, by far, the fastest computer in the world. In 1978, the Cray 1 supercomputer cost $7 Million, weighed 10,500 pounds and had a 115 kilowatt power supply. The Livermore Loops benchmark was used to accept the first supercomputer. Speeds from the ARM A6 are not as fast as those from ARM Cortex-A9 on recent Android tablets but, as we know, the Pi is usable as a proper desktop computer running Linux. This can be unzipped on the Pi and programs run from a Terminal command.įor details and example results on ARM and Intel processors see.
Executable files and source codes can be downloaded by the following.
The benchmark source code was also compiled and on a PC running Linux to confirm compatibility. These are Whetstone, Dhrystone, Linpack and Livermore Loops. I have converted my Classic Benchmarks to run on the Linux based Raspberry Pi.
