[Gems-users] regarding cmp configuration

[floydian27@xxxxxxxxx]

hi
I was trying to simulate a cmp configuration (from the tutorial and 
following some of the messages from the list)
I am getting this error message
-----------------------------------------------
Turning I-STC off and flushing old data
Turning D-STC off and flushing old data
successful installation of the ruby timing model.

simics> c
***  Simics getting shaky, switching to 'safe' mode.
***  Simics (main thread) received a segmentation fault. Will try to 
recuperate.
<Simics is running in 'safe' mode>
-----------------------------------
I am using simics version 2.0.16 I have been able to run the SMP 
protocols successfully, but all the CMP protocols (non-token) seem to 
give me this error
here is my .simics file , i m trying to load ruby after a checkpoint
read-configuration ./checkpoints/basic_32p_splash
instruction-fetch-mode instruction-fetch-trace
istc-disable
dstc-disable
load-module ruby

initial memory size in sarek

##ruby0.setparam_str  REMOVE_SINGLE_CYCLE_DCACHE_FAST_PATH false

#run-python-file "./ruby_config.py" ## this file is for supporting magic
Could u tell me if I have set any parameter incorrectly. I tried to use 
the debug facility ( i can send you a snapshot of the debug o/p file  
too, I couldnt figure out what went wrong )

Also another thing that I am interested in is regarding the CMP 
configurations u offer, does the network topology have to be 
FILE_SPECIFIED with a CMP configration, becoz I couldnt find any 
2-processor-per- chip CMP network file?  Is there a way to make one ?
