[parsec-users] counting locks of blackscholes

As an experience, I wrote a pintool to count synchronization primitives such as lucks, I think it works correctly, and most of its results are the same as table.2 in parsec technical report, but some of them are different. For example, about blackscholes, the number of locks is reported 17 by my program in the following address(it is also reported by ManualExample/proccount of pin examples), but in the table 2 it is 0. 

pthread_mutex_lock    libpthread.so.0           b65b79d0           17         

My supervisor wants to know the reason of this difference. Would you please make me sure about this? I mean whether this function must be counted for this package or by a reseon must not.

Thank you
best regards,
