[ITK-dev] [ITK] Thread Pool patch

[Bradley Lowekamp]

Jim,


Yes it was. But I set ITK_GLOBAL_DEFAULT_NUMBER_OF_THREADS to 8, and did ctest -j 8 initially, then I scaled back from there with lack of complete success in testing. There are thread management issue with the current patch.

I missed that in the patch. This is what I saw:
 m_Threadpool(m_Threadpoolfactory.GetSmartThreadPool(GetGlobalDefaul
tNumberOfThreads() * 2) )
			185	{
