•The speed of your CPU determines how quickly it can process instructions •Many bioinformatics operations fall into the “embarrassingly parallel” category
•Getting a results faster is as simple as adding more CPUs
•=> clusters
•Though clusters still dominate, increasing attention is being paid to servers with large number of cores
CPU
For current throughputs, you will need ~8 <dual quad core> nodes per sequencer to handle raw  data.
For data analysis, 1-2 nodes is enough for general purpose.
How about use Graphic Processing Unit (GPU) instead?
