MPI? Or one of the other "clustering" methodologies, I would guess. Likely communicating via Gb Ethernet. The z/Linux instances might even be communicating via NCSS shared memory. Or using some other z/VM interface for inter-guest communications (might just be TCPIP on hipersockets). I still think that one technology that would be fantastic is one that my boss insists IBM has. He says that IBM has a System z system on a card that can be put in a blade server. This same server can also accommodate pSeries and xSeries cards so that you can communicate between them on the server's memory bus (like a hipersocket does between LPARs). I do vaguely remember something like this for iSeries. Some sort of fast interface to an xServer. The xServer, running Windows, could access the iSeries' disk drives and talk to i5/OS on this "backplane" or something. -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.
