Re: [Gems-users] Opal and SMT policies

[Luke Yen <lyen@xxxxxxxxxxx>]

Kostis,

  Yes, the only fetch policy implemented in Opal for SMT is Icount, and 
is the default.
   You can find more details in opal/system/pseq.C, in the fetchInstrSimple() 
function.  There is a variable for each SMT thread called m_icount, and is 
incremented during fetch and decremented during dispatch.
