Setting Up ORNL PVM Debugging

To enable PVM, create a symbolic link from the PVM bin directory (which is $HOME/pvm3/bin/$PVM_ARCH/tvdsvr) to the TotalView Debugger Server (tvdsvr). With this link in place, TotalView can use the pvm_spawn() call to spawn the tvdsvr tasks.

For example, if tvdsvr is installed in the /opt/totalview/bin directory, enter the following command:

ln -s /opt/totalview/bin/tvdsvr \
                $HOME/pvm3/bin/$PVM_ARCH/tvdsvr

If the symbolic link does not exist, TotalView cannot spawn tvdsvr. If this happens, TotalView displays the following error:

Error spawning TotalView Debugger Server: No such file
