 You can generally ignore this. The environment variable (env var) ITK_GLOBAL_DEFAULT_NUMBER_OF_THREADS is used by ITK-based apps like ANTs, ITK-SNAP. Your script is setting this variable to a value of 1, which means ITK apps will be single-threaded, //and// it's calling qsub with the -V option which exports your env vars to the qsub job. But the cluster is setup for qsub so it automatically sets the ITK_GLOBAL_DEFAULT_NUMBER_OF_THREADS variable depending on how many slots you've requested for your job. So this message is saying the value for ITK_GLOBAL_DEFAULT_NUMBER_OF_THREADS that your script has set is being unset, i.e. ignored, so that the value can be reset using the number of slots you've requested. You can generally ignore this.

 If you want to get rid of this warning, you'll need to examine your job script and remove the definition of ITK_GLOBAL_DEFAULT_NUMBER_OF_THREADS. We don't suggest removing the -V from the call to qsub unless you know for sure that qsub doesn't need other env vars to be passed to it. If you want to get rid of this warning, you'll need to examine your job script and remove the definition of ITK_GLOBAL_DEFAULT_NUMBER_OF_THREADS.
