[Gems-users] Warm Applications...

["Kyueun Yi" <kyueuny@xxxxxxx>]

Hi,

 

I found the following link:

https://lists.cs.wisc.edu/archive/gems-users/2006-March/msg00143.shtml

 

I followed the steps to make warm checkpoint in the above link.

However, It looks my simulator is stopped.

I did the following steps to make warm checkpoint.

 

1. make OS Checkpoint

 

cd GEMS/simics-2.2.19/home/sarek

./simics

simics> write-configuration CHKPT_DIR/sarek-16p.check

simics> quit

 

2. make cold Checkpoint

 

since I wish to "use MOESI_CMP_directory",

cd GEMS/simics-2.2.19/home/MOESI_CMP_token

./simics

simics> read-configuration CHKPT_DIR/sarek-16p.check

(simics> magic-break-enable) <== I didn't take this step since my application didn't have MAGIC_BREAKPOINT.

simics> c

 

<YellowConsole> /mount /host

<YellowConsole> cd /host/MyAPP/

<YellowConsole> myapp 100

myapp showed correct results here in YellowConsole.

 

simics>CTRL+C

simics> write-configuration CHKPT_DIR/myapp-cold-16p.check

simics> quit

 

3. make warm Checkpoint

cd GEMS/simics-2.2.19/home/MOESI_CMP_token

 

./simics -stall

#Read configuration

simics> read-configuration CHKPT_DIR/myapp-cold-16p.check

 

#Load python scripts

simics> @sys.path.append("../../../gen-scripts");

simics> @import mfacet

 

#Configure Simics

simics> instruction-fetch-mode instruction-fetch-trace

simics> istc-disable

simics>dstc-disable

(simics> magic-break-enable) <== I didn't take this step since my application didn't have MAGIC_BREAKPOINT.

 

#Load module

simics> load-module ruby

 

#Initialize

simics> ruby0.init

simics> c

 

My question is:

   After type "c" in simics, the YellowConsole is changed to (running) state.

   But I can't type anything in YellowConsole. Did I take wrong steps in described above?

 

(After last step above, I will take steps as following)

<YellowConsole> myapp 100

 

simics> ruby0.save-caches myapp.chache.gz

simics> write-configuration CHKPT_DIR/myapp-warm-16p.check

 

Thanks in advance for any help.
