      • ENVIRONMENT

        public static VirtualMachine ENVIRONMENT
        This is set for you, but you may want to set it to something different/better. Create a Hardware instance and then call Hardware.virtualise(). The idea is that the Hardware instance should match the actual hardware, but the VirtualMachine can optionally be limited to only let ojAlgo "see" a subset of the cores/threads. Changing this must be the very first thing you do with ojAlgo.
