7.6. Benchmarks
In this section, we discuss industry standard benchmarks performed on pSeries running Linux.
7.6.1. System configurations
Hardware
Eight p655 nodes (lp01-08) interconnected by the Myrinet 2000 switch. Each node has eight 1.1 GHz POWER4 processors, private 32 KB L1 Data and 64 KB L1 Instruction cache per processor, 4×1.44 MB L2 cache, 32 GB memory, two Myrinet D-cards.
Two of the nodes (lp07, lp08) have direct peer-to-peer Gigabit Ethernet connection. The schematic diagram is shown in Figure 7-2 on page 318.
