Setting Up ORNL PVM Debugging
To enable PVM, create a symbolic link from the PVM bin directory (which is usually $HOME/pvm3/bin/$PVM_ARCH/tvdsvr) to the TotalView Server (tvdsvr). With this link in place, TotalView invokes pvm_spawn() 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 doesn’t exist, TotalView can’t spawn tvdsvr, displaying the following error:
Error spawning TotalView Debugger Server: No such file
