Performing a Remote Login
You must be able to perform a remote login using the rsh command. You also need to enable remote logins by adding the host name of the remote node to the /etc/hosts.equiv file or to your .rhosts file.
When the program is using switch-based communications, MemoryScape tries to start the TotalView Server by using the rsh command with the switch host name of the node.
Setting Timeouts
If you receive communications timeouts, you can set the value of the MP_TIMEOUT environment variable; for example:
setenv MP_TIMEOUT 1200
If this variable isn’t set, the default timeout value is 600 seconds.
