Systems and methods for managing data, such as metadata. The exhaust gas recirculation system includes an EGR valve fluidly coupled between the exhaust manifold and the intake manifold. In the described embodiment, a data value stored within the first cacheable memory location is accessed via a conditional load instruction in response to a determination that the loadstore operation reservation on the first cacheable memory location has been reset. The Mg\u2014Ni based alloy has a microstructure including both a Mg-rich phase and a Ni-rich phase, micro-tubes having an inner core of Ni-rich material surrounded by a sheathing of Mg-rich material, amorphous structural regions and microcrystalline structural regions.
