You can call maxNumCompThreads(N) in Matlab and should be able to set the number of threads like that. Or start Matlab with the -singleCompThread option. Let us know if that changes the behavior. Maybe there are some global settings for maxNumCompThreads that Predrag can change. <div class=""><br class=""></div><div class=""><div class=""><div class=""><div><br class=""></div><div><br class=""><blockquote type="cite" class=""><div class="">On Sep 25, 2018, at 5:09 PM, Matthew Barnes <<a href="mailto:mbarnes1@andrew.cmu.edu" class="">mbarnes1@andrew.cmu.edu</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class="">Starting a simple instance of matlab on the servers creates about 50 processes.
