[Insight-users] Problem with multi-threaded metric computation

[Florence Dru]

Hello,
here is my problem: I have parallelized a part of my program that calls 
the "GetValue()" function of my cost function object.
I used the itkMultiThreader class to do this.
But the problem is that when I use more than 1 thread, when the cost 
function object is evaluated a one point the returned values are 
completely incorrect ( in the order of 200 instead of the usual order of 
0.3) and I was wondering whether it could come from the different 
threads that access the same object at the same time, messing up everything.
Could someone help me ?
Thanks beforehand for replying.
