[Gems-users] "failed assertion" when running gems/ruby with Dnuca

[alessandro.bardine@xxxxxxxxxxxx]

I am using gems (MOESI_CMP_NUCA) with the following parameters and commands:
istc-disable
dstc-disable
instruction-fetch-mode instruction-fetch-trace
load-module ruby
load-module opal
ruby0.setparam g_NUM_PROCESSORS 8
ruby0.setparam g_PROCS_PER_CHIP 8

ruby0.setparam L1_CACHE_ASSOC 4
ruby0.setparam g_NUM_L2_BANKS 256
ruby0.setparam L2_CACHE_NUM_SETS_BITS 8
ruby0.setparam L2_CACHE_ASSOC 4
ruby0.setparam_str g_NETWORK_TOPOLOGY FILE_SPECIFIED
ruby0.setparam_str g_DYNAMIC_TIMEOUT_ENABLED false

ruby0.init
opal0.init
opal0.sim-start "output-dnuca.opal"
opal0.sim-step 3
ruby0.dump-stats "output-dnuca.ruby"
opal0.stats


and I get the following error when the sim-step starts:

...

At this point you might want to attach a debug to the running and get to the
crash site; otherwise press enter to continue

I have tried various L2 cache size for block and associativity but I always 
get the same error.
Where am I wrong?
