[Gems-users] load module ruby error

[shanshuchang <shanshuchang@xxxxxxxxx>]

Hi all:
I have got a problem when I tried to load module ruby.
Firstly I run, wrote a 2-processor checkpoint and then read  the
configuration file like this:(GEMS2.1 + simics 3.0.31)


(1)I run abisko-multi.simics and it triggered two xterm
(2)When the xterm console "#"appeared,I press ctrl+c to back to simics
and pressed command "write-configuration abisko-2p.conf"
(3)quit simics and read the checkpoint file again:
shuchang@localhost:~/gems/simics/home/MOESI_CMP_token$ ./simics -stall
-c ../../../simics-3.0.31/bin/CHECKPOINT/abisko-2p.conf

after that,I configure the simics and tried to load ruby when the error
occurred:
simics> instruction-fetch-mode instruction-fetch-trace 
[a1_cpu0 info] Note that on this cpu, instruction-fetch-trace is
implemented using instruction-cache-access-trace with a suitable cache
line size.
[a2_cpu0 info] Note that on this cpu, instruction-fetch-trace is
implemented using instruction-cache-access-trace with a suitable cache
line size.

The switch time will change to 1 cycles (for CPU-0) once all processors

However, when I tried to load my first_step.conf OS checkpoint and load
module ruby,no error occurred.The first_step.conf OS checkpoint was
written from abisko-common.simics by almost the same method...

sorry for such a long mail...
Can anyone help me and tell me how to create a checkpoint to build some
workloads’ multiprocessor checkpoints(such as 2-processors)?
