[Gems-users] GEMS 2.0: Problem with XACT_MEMORY set to true

["Arnab Sinha" <sinha@xxxxxxxxxxxxx>]

Hi,

 

I am trying to run LogTM in the GEMS 2.0. I compiled MESI_CMP_filter_directory protocol with the following parameters in $gems_root/ruby/config/rubyconfig.defaults.

 

PROFILE_EXCEPTIONS: false

PROFILE_XACT: true

PROFILE_NONXACT: false

XACT_DEBUG: true

XACT_DEBUG_LEVEL: 1

XACT_MEMORY: true  // set to true for TM protocols. set it HERE for lazy systems to register the proper SIMICS interfaces

XACT_ENABLE_TOURMALINE: false // perfect memory system

XACT_NUM_CURRENT: 0 // must be 0

XACT_LAST_UPDATE: 0 // must be 0

XACT_ISOLATION_CHECK: false // Checks whether each memory access preserves transaction isolation

 

After compilation when I try to run, I get the following error after ruby initialization, which vanishes if I set XACT_MEMORY to false:

 

Ruby initialization complete

***  Simics getting shaky, switching to 'safe' mode.

***  Simics (main thread) received an abort signal, probably an assertion.

Starting command line. (May have skipped commands in script files.)

 

I have no idea, why this is happening. Please someone advise.
