Visit www.sortbenchmark.org to download the dataset generation tool for Indy (the version used during 2009 and 2010 benchmarks). 
Should generate 100-byte records: 10 byte key followed by 90 byte payload.

./naskitis_non_commercial_ozsort_stage_one <file-name-to-sort>  // this file will be overwritten with sorted runs. 
./naskitis_non_commercial_ozsort_stage_one <file-name-to-sort> <file-name-to-write-out-to>

You need a 64-bit Linux machine with at least 4GB of RAM to run this 
software, plus lots of disk space (and preferably a RAID-0 HDD setup) with custom Kernel
and TLB configurations to achieve high-performance.
