A Linux operating system was used (CentOS 6.4 64 bit) with an OCZ 128 GB SSD hard drive. The theoretical performance for single (32 bit floats) and double (64 bit floats) precision is given as giga floating point operations per second (GFLOPS). Prices are from newegg.com and should be seen as approximate.
