Running the server

The HPVM front-end server is started by logging on as the LSF administrative username (usually `lsfadmin') to the host in the LSF cluster that is running the Web server from which the HPVM front end Java client is loaded. Once logged on, open a Command Prompt window and type the name of the HPVM front-end server executable (usually `HPVM_Server.exe'). You will see a message on the console indicating that the server has started. You must remain logged in to the console while the server is running.

The HPVM front-end server must be run on the host in the LSF cluster that is running the Web server from which the HPVM front-end client is loaded due to security restrictions in the Java Virtual Machine. Under the Java security model, applets may open a TCP/IP socket connection only with the host from which they were loaded. Thus, in order for the client to establish a socket connection with the server, the server must be running on the host from which the client applet was loaded.

During the course of its operation, the HPVM front-end server must perform various privileged operations on both the Windows NT system running the server and on the LSF cluster hosts. By running the server under the LSF administrative username, the privileges required for correct operation are present.
