Benchmarks
NAS BTIO Parallel I/O Benchmarks :
“simple” benchmark : primitive data types, no collective I/O.
“full” benchmark : complex, user-defined datatypes, collective I/O
Both versions perform lots of seeks, but only write data.
Out-of-core matrix multiplication : rudimentary algorithm, data stored in files, reads matrix rows and columns, writes rows, uses user-defined datatypes, collective I/O is optional.
Performs many seek, read, and write operations.
Synthetic : generates random read and write requests with the starting address, request size, and read/write ratio generated by stochastic functions (normal and exponential distributions).
