// Allow a shared computer to run smoothly when it is being used
// by students in a CUDA GPU programming course.
//
// TA_Utilities.cpp/hpp provide functions that programatically limit
// the execution time of the function and select the GPU with the
// lowest utilization for kernel calls. Utilization is determined by
// finding each GPU's temperature and memory usage and creating a
// "utilization score" that weighs these two factors equally.
