Would you accept the first format (line per node) as a compromise? (Note there will be 256 node systems w/4096 threads as well as 512 node systems w/HT disabled thus still 4096 threads.) Btw, I think we should keep the processor summary as it does show some useful information. Agreed? (... I'll clean up the BogoMIPS line a bit: BogoMIPS(lpj): MIN xxx (yyy) AVG xxx (yyy) MAX xxx (yyy) ...) Thanks, Mike 64 Nodes/512 cores/1024 threads...
