In fact, it has been there since 90s and very popular in cluster computing paradigm. And teh next thing I learn is that its free only for upto 32 nodes. <br /><br />Secondly, read this paper on Fault-tolerant MPI from Frank Copello's group. I have a feeling they are doing excellent research in distributed computing. Applying distributed computing concepts (failure-masking, checkpointing) to real applications. <br />Indeed, if large scale and parallel distributed (LSPD) computing were to materialize, we would run into a situation with volatile and untrusted nodes. This is not so big an issue for file-sharing systems, since there is no accountability. <br /><br />Not ofcourse when you use the desktop nodes to run some real scinetific computation. <br />Can't ignore failues, node-compromises, security issues, secure computation. <br /><br />Thats it...<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18915524-113229135849202875?l=aganguly.blogspot.com' alt='' /></div>Hypervisorhttp://www.blogger.com/profile/13234906632147868520noreply@blogger.com0tag:blogger.com,1999:blog-18915524.post-1131856725974264592005-11-12T20:38:00.000-08:002005-11-14T09:39:22.120-08:00For a brief introduction to virtualization <br /><a href="http://www.kernelthread.com/publications/virtualization/">click here</a><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18915524-113185672597426459?l=aganguly.blogspot.com' alt='' /></div>Hypervisorhttp://www.blogger.com/profile/13234906632147868520noreply@blogger.com0
