Future of hyper threading, Computer Engineering

Current Pentium 4 based MPUs use Hyper-threading, but the next-generation cores, Woodcrest and Merom, Conroe will not. While some have alleged that this is because Hyper-threading is somehow energy inefficient, this is not the case. Hyper-threading is a particular form of multithreading and multithreading is surely on Intel roadmaps for the generation after Conroe/ Merom /Woodcrest. Rather a few other low power chips use multithreading, having the PPE from the Cell processor, the CPUs in the Play station 3 and Sun's Niagara. Regarding the future of multithreading the real question is not whether Hyper-threading will return, as it will, but rather how it will work. Presently, Hyper-threading is identical to Simultaneous Multi-Threading, but future variants may be dissimilar. In future trends parallel codes have been simply ported to the Pilot Cluster, often with improved results and Commercial Resource Management Systems and Public Domain have been evaluated in the Pilot Cluster Environment. The proposed enhancements in this architecture are as follows:

  • Management of wider domains with collaborating departments
  • Further developments in Heterogeneous Systems
  • Inter-campus computing
  • Faster communications
  • High Performance language execution
