The Mirage III has approximate dimensions (length,wingspan,height) of 15m x 8m x 4.5m. Or, measured in terms of freespace wavelength at 850 MHz, 42.5 lambda x 22.66 lambda x 12.75 lambda. Thus, for the purposes of [[EM.Tempo]], we need to solve a region of about 12,279 cubic wavelengths. For problems of this magnitude, a great deal of CPU memory is needed, and a high-performance , multi-core CPU is desirable to reduce simulation time.
Amazon Web Services allows one to acquire high-performance compute instances on demand, and pay on per-use basis. To be able to log into an Amazon instance via Remote Desktop Protocol, the [[EM.Cube]] license must allow terminal services (for more information, see [[EM.Cube]] Pricing). For this project, we used a c4.4xlarge instance running Windows Server 2012. This instance has 16 virtual CPUs, and 30 GiB of memory.
