Re: [Gems-users] simulation state corrupted

[Polina Dudnik <pdudnik@xxxxxxxxx>]

Remember, you cannot load ruby before you started a workload. In general, what would happen is this: you read the configuration file with read-config, then a yellow window pops up. You copy your binary or what not into the simulated machine and start running it. So, say copy hello_world into the simulated machine and then do ./hello_world in the yellow window. Your hello world binary needs to have a magic call in it. When the simulation hits the point where the magic call is the simulation will be suspended and this is when you load ruby. You cannot load ruby unless you have a running workload.

I start simics with "./simics -stall", and the error happens just after I input the fallowing order, before I can do anything with the target machine

主题： Re: [Gems-users] simulation state corrupted

What benchmark are you running?  Could you give us more output? What is the output before it tells you that the simulation state has been corrupted?

hi,

I encounter a problem with error: "The simulation state has been corrupted. Simulation cannot continue"

and my ruby configuration shows as fallowing:

*********************************

ruby0.setparam g_NUM_PROCESSORS 2
ruby0.setparam g_MEMORY_SIZE_BYTES 2147483648
ruby0.setparam g_PROCS_PER_CHIP 2
ruby0.setparam NUMBER_OF_VIRTUAL_NETWORKS 5
ruby0.setparam XACT_DEBUG_LEVEL 0
ruby0.setparam_str PROFILE_XACT true
ruby0.setparam_str XACT_MEMORY true
ruby0.setparam_str XACT_LAZY_VM true
ruby0.setparam_str XACT_EAGER_CD false
ruby0.setparam_str REMOVE_SINGLE_CYCLE_DCACHE_FAST_PATH true
ruby0.setparam_str XACT_CONFLICT_RES BASE
ruby0.setparam_str USER_MODE_DATA_ONLY true
#ruby0.setparam_str XACT_ISOLATION_CHECK true

*********************************

If I changed "XACT_EAGER_CD" to "true", everything goes well.

 

Is there any thing I can do if want to use the "XACT_EAGER_CD" as "fase"

 

Thanks for any help!
