There was an undergrad thesis at DLSU implementing a DSM over PVM. With that implementation, shared memory allocation was partly being handled by the PVM and so with the message passing concern (communication). According to my adviser, they will be building another one but this time, it will be on top of MPI. So shared memory allocation will be handled on the higher level (w/in their DSM software) while leaving the network communication at the MPI level. Most papers I've read about software-oriented DSM have used the MPI as the base architecture. They only differ on the higher level, that is, how they present the DSM address space to the programmer. It could be a page-based DSM, or as shared objects accessible via well-defined set of operations as insert, delete, etc. I'll be implementing a DSM, probably, I'll use the MPI. I'll be using this implementation to further verify the results of my thesis on access semantics- driven DSM, which I'm defending on Tuesday. Currently, I'm only using a simulator for a lazy release consistent DSM to verify my claim. wtg dean! -- When you innovate, you've got to be prepared for everyone telling you you're nuts! --larry ellison ___________________________________________________________________________ Committed to Excellence in Science and Technology http://www.msuiit.edu.ph/ Are you a student of MSU-IIT?
