You can also use Oracle Solaris Studio to profile your application
using one of the TLB HW counters. Various counters are available
depending on the precise Opteron chip model.
To do such a profile:
collect -h l2dtlbm a.out args
will collect a statistical profile, and show which functions and source
lines had the most L2 DTLB misses.
