The use of Globus immediately affords a set of distinct features to the HPC++ environment. Globus provides an extensive layer of authentication between the client and the server, based on public/private key cryptography. The Globus GRAM mechanism is used to authenticate a user before he/she is allowed to start new processes on a machine. HPC++ uses this mechanism to implement its feature of remote context creation. Thus, HPC++ remote context creation using the Globus based run-time system always involves mutual authentication between the client and the server. Globus GRAM can also be used to start jobs on specific nodes of a remote parallel supercompuuter such as an SP2.
