Breaking the I/O Bottleneck with the CRAY Solid-State Storage Device
The use of the CRAY Solid-state Storage Device as a secondary memory device for large-scale problems in computational fluid dynamics is reported. The high data transfer rate and low access time of the SSD essentially eliminates the I/O-wait penalty. Hardware details, user impact (minimal, the SSD is used like a conventional disk drive), several examples of its use, and the relative performance of I/O types are discussed.
