Re: [Gems-users] transactional memory and Opal

["huitzu shih" <huitzu.shih@xxxxxxxxx>]

I used GEMS-2.1 and simics-2.2.19 to run deque-tm.

But when I use ruby+opal module to execute it , I miss the transcational memory information. All "Transactional Memory Stats" are zero. (Show below)

I use opal to get the WATTCH power information. In other words, I want to execute the transactional memory program and get WATTCH power information. 

Are there any solutions?

Please help me! Thanks

  The version of Opal for the GEMs release does not support running TM
programs.
  However with alot of non-trivial work it can be made to run TM programs.
Most of the complexity comes in how to track transactional loads/stores
for correct conflict detection, and how to handle stalls & aborts.
