Hi Steven,<br><br>Thanks for your suggestions and sorry for the late reply. I contacted our cluster admin and the problem seems to be on some restriction policies which do not allow to create pthreads within the cluster. So, it is solely a cluster problem and has nothing to do with ITK itself.<br>

I am trying to run some ITK code on a linux cluster at my university and I get the following exception:<br>
<br>
terminate called after throwing an instance of 'itk::ExceptionObject'<br>
what(): /home/ubelix/artorg/cseiler/tmp/InsightToolkit-3.10.2/Code/Common/itkMultiThreader.cxx:475:<br>
itk::ERROR: MultiThreader(0x12a1c50): Exception occurred during SingleMethodExecute<br>
/home/ubelix/artorg/cseiler/tmp/InsightToolkit-3.10.2/Code/Common/itkMultiThreader.cxx:901:<br>
itk::ERROR: MultiThreader(0x12a1c50): Unable to join thread.<br>
/var/spool/sge/anode16/job_scripts/9909286: line 23: 30063 Aborted (core dumped) ./cvsampler ../data/DVF/femur-l-Segmented/ ../data/reference/Reference-Classified-SLICES 2 3<br>
<br>
I tried setting the number of threads to one:<br>
itk::MultiThreader::SetGlobalDefaultNumberOfThreads(1);<br>
<br>
But still get the same exception. The cluster runs on Sun Grid Engine (SGE). Everything works fine when I start the program in a non-cluster environment.<br>

I've seen issues like this before, mainly related to the incorrect threading library being used (e.g. compiling with the Intel compiler.. using gnu pthreads..).<br>
<br>
I would check out which pthread libraries are being loaded when you run your code in the cluster environment..<br>
<br>
As a check - are you able to successfully run some simple pthread code through SGE? Or even OpenMP code.<br>
<br>

Any ideas would be very much appreciated.<br>
