High Performance Computing 1
Wide 77 Node Performance
•Theoretical peak performance:
–2*77 = 154 MFLOP for dyad
–
–4*77 = 308 MFLOP for triad
•Cache Effects dominate performance
–
•256 KB Cache and 256 bit path to cache and from cache to memory -- 2 words (8 bytes each) may be fetched and 2 words stored per cycle
•
