Abstract

In an approach to dynamic redistribution of register files, whether a redistribution of register files is necessary is determined. Responsive to determining that the redistribution of register files is necessary, one or more register file transfers that have not yet completed are flushed. One or more register file write locations are allocated for each architected register based on a register free list. Source data is read from each architected register. The source data is written to the one or more register file write locations.
