PVM Compatibility LAM also has a library to run PVM 3 applications. As with MPI, there are debugging commands to examine the PVM synchronization status of processes and messages. Configuration and Process Management LAM unpacks and installs anywhere. The user shell's search path is used to locate the LAM server, utilities and application programs on every machine. Configuring a cluster is listing machine names in a file and invoking a utility.
Process management is completely dynamic.
The user or any process situated at any machine can run a program residing in any second machine on any third machine. NFS is not required. The user or any process can kill any other process. An executable may reside in the target node's file space or LAM can transfer the file from a third node. User Interface LAM's UI is just your usual shell.
