I was thinking, technically he could make use of his unix machines in his winblows environment to a limited degree.

If he installed cygwin, and built some cross compilers on his unix machines, he should be able to compile distcc for ditributed compiling on his winblows machine. I've never tried it, but I'm sure it would be possible.

There are other things you could do to speed up a windows environment. Take blender for example, I belive it has some network rendering stuff it in and it is cross platform.

As for transparent clustering windows + unix, it ain't gonna happen.

And on another note about mosix, keep in mind it is designed for transparent computational clusters, ie. number crunching machines. It'll speed up things like a multi-threaded, CPU bound processes, but stuff that is IO bound will not migrate to the other nodes. Don't think it'll speed up your [insert favorite 3D video game here] because it won't.

As with everything in unix, the tools are there. It's how you use them that makes it worthwhile. If you do not want to learn how to use the tools, or want the computer to do something (half-assed) for you, stick with winblows.

lamnodes

LAMNODES(1)							     LAM TOOLS							       LAMNODES(1)

NAME

       lamnodes - Resolve LAM node/CPU notation to Unix hostnames.

SYNOPSIS

       lamnodes [-chin] [where]

OPTIONS

       -c	   Suppress printing the CPU count for each node.

       -h	   Print the command help menu.

       -i	   Print IP addresses (instead of IP names)

       -n	   Suppress printing CPU count for each node

DESCRIPTION

       The  lamnodes command is used to resolve LAM node/CPU nomenclature to Unix hostnames.  It can be used to determine the current running con-
       figuration of the LAM/MPI run-time environment, and generate a boot schema that can be used to launch LAM in the future.

       By default, lamnodes will print out the node number, default IP name, CPU count, and per-node flags for	each  node  in	the  running  LAM.
       gethostbyaddr(3) is used to obtain default hostnames.  If gethostbyaddr(3) fails, the IP number is displayed instead.

       This  command  can be used by setup shell scripts (and the like) to determine information from a currently-running LAM universe.  For exam-
       ple, use lamnodes to resolve particular CPUs and/or nodes to specific unix hostnames.  In a batch environment,  lamnodes  can  be  used	to
       determine which CPUs share a common node (note that MPI_GET_PROCESSOR_NAME can be used for a similar effect in an MPI program).

       lamnodes also shows per-node flags.  Currently defined flags are:

       origin	   The node where lamboot was executed.

       this_node   The node where lamnodes is running.

       no_schedule The node will not be used to run MPI and serial processes when N and C are used to mpirun and lamexec.

EXAMPLES

       lamnodes N -n
	   Display IP names and CPU counts for all nodes.  This output can be saved and later used with lamboot(1).

       lamnodes C -n -c
	   Display  the  IP  name  of the nodes containing each CPU, and suppress the LAM node number and CPU count.  This output can be saved and
	   later used with lamboot(1).
