FORTRAN implementation of a network executive under IBM's VM/CMS

OSTI ID:5255126
The Lawrence Berkeley Laboratory Computation Department has attached an IBM-4331 to a heterogeneous local network. The network, named THC, uses Network Systems Corporation HYPERchannel hardware to implement a general process-to-process communication scheme. It appears to the user as an extension of the local operating system accessed by a subroutine call. The executive multiprocesses requests from different user virtual machines and exchanges messages with other nodes on the network. We describe an assembly-language module, occupying one page of memory, which allows the straightforward CMS-FORTRAN implementation of such an executive as a virtual machine, requiring no modifications whatsoever to the standard operating system. We then describe our network executive as an example of its use.
