i've googled for NUMA, and some links pointed me to a specialized architechture for multiple processor computers. thanks for the idea, although this is not what i'm really after. > > Although I think it is possible to have a shared-across-nodes shared > memory segment using the PVM or MPI libraries (google for it). > these are some of the options i have in my list of technologies that i would be able to use. but what i'm really after is a standard or simple way of doing it. i could use PVM and MPI for this purpose in mind, but i am still looking for alternatives. i'm currently reading books on both PVM and MPI to get my feet wet. now what i really want to do is to create a programmable distributed virtual machine for general computational purposes. sharing information between the nodes is crucial for a coherent and synchronized distributed system, and having to do it using existing libraries would be great for developers like me. however, i was wondering if using either PVM and/or MPI in my implementation would have significant and unwanted effects on the operation of my virtual environment. this is something that might be uncovered in the course of testing and debugging, but should nonetheless be explored beforehand. thanks again, coz the idea is really helpful. i was just wondering if there was a standard way of doing it (something like from the glibc, or the system programming header files) but it seems that i _do_ need to use PVM amd/or MPI. ;) anybody has any takes on mosix? ;) -- -=[mikhail]=- aka Dean Michael C.
