A researcher needs to regularly analyze large quantities of data.  They are interested in putting together a cluster of 16 UDB EEE partitions of four processors each for their data mining environment.  Each UDB partition needs to be approximately 15 rPerf.  Which of the following solutions would best fit their performance needs？（）

• A、p655 4-way nodes
• B、p655 8-way nodes
• C、p5-570 4-way nodes
• D、p5-570 8-way nodes
