String searching or pattern matching are important to a variety of commercial, government and HPC applications. One of the core functions needed for text identification algorithms in data repositories is real-time string searching. A recent Aho-Corasick algorithm for string searching was used for benchmark testing the Sun SPARC Enterprise T5220, T5240 and T5440.

Reporting on the BestPerf blog, Russell Brown identified unique findings from using the Aho-Corasick string searching algorithm, namely:

Sun SPARC Enterprise T5440

Midrange server

• A 1.6 GHz Sun SPARC Enterprise T5440 server could search a book as tall as Mt. Everest (29,208 feet, 861 GB book) in 61 seconds, which corresponds to a string search rate of 14.2 GB/s.

• A 1.6 GHz Sun SPARC Enterprise T5440 server can search at a rate of 14.2 GB/s, which corresponds to searching a book containing one terabyte of data (34,745 feet high) in only 70 seconds.

• The 4-chip 1.6 GHz Sun SPARC Enterprise T5440 server performed string searching at a rate of 14.2 GB/s which is 29.9 times as fast as the 2-chip IBM Cell Broadband Engine DD3 Blade that performed string searching at a rate of 0.475 GB/s

• The 4-chip 1.6 GHz Sun SPARC Enterprise T5440 server performed string searching 3.7 times as fast as the 4-chip HP DL-580 (2.93 GHz Xeon QC) server that performed string searching at a rate of 3.87 GB/s. The 1.6 GHz Sun SPARC Enterprise T5440 server has a 1.7 times advantage in delivered power-performance over the HP DL-580 (using a power consumption rate of 830 watts for the HP system as measured on other tests).

• The 1.6 GHz Sun SPARC Enterprise T5440 server demonstrated a 12% improvement over the 1.4 GHz Sun SPARC Enterprise T5440.

• The 1.6 GHz Sun SPARC Enterprise T5440 server demonstrated a 2x speedup over the 1.6 GHz Sun SPARC Enterprise T5240 server which demonstrated a 2.3x speedup over the 1.4 GHz Sun SPARC Enterprise T5220 server.

Sun SPARC Enterprise T5240

Entry-level server

• The 2-chip 1.6 GHz Sun SPARC Enterprise T5240 server performed string searching at a rate of 7.22 GB/s which is 15.4 times as fast as the 2-chip IBM Cell Broadband Engine DD3 Blade that performed string searching at a rate of 0.475 GB/s.

• The 2-chip 1.6 GHz Sun SPARC Enterprise T5240 server performed string searching 1.9 times as fast as the 4-chip HP DL-580 (2.93 GHz Xeon QC) server that performed string searching at a rate of 3.87 GB/s. The 1.6 GHz Sun SPARC Enterprise T5240 server has a 2.4 times advantage in delivered power-performance over the HP DL-580 (using a power consumption rate of 830 watts for the HP system as measured on other

• The 1.6 GHz Sun SPARC Enterprise T5240 server demonstrated a 14% speedup over the 1.4 GHz Sun SPARC Enterprise T5240 server.

Sun SPARC Enterprise T5220

Entry-level server

• The 1-chip 1.4 GHz Sun SPARC Enterprise T5220 server performed string searching at a rate of 3.16 GB/s which is 6.7 times as fast as the 2-chip IBM Cell Broadband Engine DD3 Blade that performed string searching at a rate of 0.475 GB/s.
