[Gems-users] Fatal Error: in fn virtual void Sequencer::wakeup() in system/Sequencer.C:112: Aborting

["Mark Gebhart" <mgebhart@xxxxxxxxxxxxx>]

Hi,

 

I am trying to run a LogTM program using Simics 3.0.22 and GEMS 1.3 and the abisko-common target script with Solaris 10.  I have tried both MOESI_SMP_LogTM_directory and MESI_SMP_LogTM_directory.  Things work fine with 1 thread but as soon as I go to 2 threads I get the following warnings followed by a fatal error:

Fatal Error: in fn virtual void Sequencer::wakeup() in system/Sequencer.C:112: Aborting

Abort (SIGABRT) in main thread

The simulation state has been corrupted. Simulation cannot continue.

Please restart Simics.

 

What can I do to prevent this deadlock from occurring?  My program consists of a main loop with a BEGIN_TRANSACATION(0) followed by a call to a work function followed by an COMMIT_TRANSACTION(0).

 

Any advice would be greatly appreciated.

 

Thanks,

Mark
