[Gems-users] ruby configuration and FFT results

[nikiforg@xxxxxxxxxx]

Hi all,
In the wiki documentation, it is declared as important to follow some steps as:

  simics> instruction-fetch-mode instruction-fetch-trace
  simics> istc-disable
  simics> dstc-disable
  simics> cpu-switch-time 1

configuring ruby as above, the results of the SPLASH2 FFT running on
MOSI_SMP_Bcast are not good! There is no scalability! System with 2 CPUs is
faster than any aother system! If I do not follow the steps above, everything
seems OK(scalable up to 8 CPUs).

Something else I want to ask is about L1 ang L2 caches and their size! Where can
I configure them!
