Abstract
In March 2004, the Nsort program was able to sort 34 GB of data (340,000,000 100-byte
records) in 58 seconds on a 32 processor Itanium® 2 NEC® Express5800/1320Xd running
Microsoft® Windows® Server 2003 Datacenter Edition. This set new records for the
MinuteSort benchmark. The data was read from one input file at 1.4 GB/sec. The output file was
created and written at 1.2 GB/sec. Both files resided on an NTFS file system on a striped logical
volume consisting of 8 Eurologic 14-disc SAN blocs attached by 8 Qlogic 2350 SAN HBAs. The
34 GB data set was read into main memory, sorted, and written to the output file. No temporary
(or scratch) files were used. In April 2004 on the same NEC server, Nsort was able to sort a 1 TB
file in 33 minutes using 21 Qlogic HBAs and 41 Eurologic SAN blocs. This set a new record in
the TeraByte Sort benchmark.
