In Table 3.3 we have sorted all different performance types showing up in the TOP500 and include the number of their appearances. Figure 3.2 shows individual as well as accumulated performances with respect to the positon in the TOP500. Figure 3.3 shows the same data for the first hundred entries only.
Low values are typical for vector machines where MPPs often show quite high ones.
This indicates that you have to run bigger problems on MPPs to achieve good efficiencies. This is due to the fact, that their DRAM memory chips are cheaper than the SRAM memory chips of the vector machines. J. Supercomputer Appls.
