We propose an inter-slave communication scheme for three well known dynamic methods: CSS [23], TSS [13] and DTSS [6]. In all cases, after the master assigns chunks to slaves, the slaves synchronize by means of synchronization points. misterwives and lawrence

WebIn computer architecture, register renaming is a technique that abstracts logical registers from physical registers. Every logical register has a set of physical registers associated with it. When a machine language instruction refers to a particular logical register, the processor transposes this name to one specific physical register on the fly.
