Original Abstract Submitted

A computing device includes last level cache (LLC) for processing cores and a separate input/output (I/O) LLC for use in facilitating data transfers between the computing device and one or more I/O devices. The I/O LLC is configured to include a set of partitions corresponding to a set of classes. Usage of the partitions in the set of partitions is monitored and the set of partitions is dynamically adjusted based on the usage. A process in a particular one of the classes makes a data request and a particular one of the partitions associated with the particular class is used in the data request.
