Speaking of GpH, I wonder how is GdH coming along? It seems that the installation instruction on http://www.cee.hw.ac.uk/~dsg/gdh/ is still incomplete...
As far as I know, Mosix has nothing to do with PVM, so am I right to say that GpH still needs PVM even you use it on a Mosix cluster? Then what will Mosix provide when you can have a PVM cluster without Mosix running the same thing?
GpH needs PVM. The difference between PVM and mosix is that PVM requires the user to specify the processor on which tasks execute. I am beginning to investigate whether or not mosix will migrate PVM tasks, and if not, how this can be arranged. Mosix provides automatic load balancing, which is one of our major research interests. You are correct that PVM alone can be used for construction of a cluster; it is just that PVM clustering is not the kind of clustering we wish to achieve. And we may not even be able to get GpH to run on a non-shared-memory cluster. We may or may not be able to achieve our goals, but finding out is what research is all about, isn't it? :) Best, Murray Gross
