Debugging PVM (Parallel Virtual Machine) Applications
You can debug applications that use the Parallel Virtual Machine (PVM) library with TotalView on some platforms. TotalView supports ORNL PVM Version 3.4.4 on all platforms.
NOTE >> See the Platform Guide for the most up-to-date information regarding your PVM software.
For tips on debugging parallel applications, see Chapter 15, “Debugging Strategies for Parallel Applications” .

Supporting Multiple Sessions
When you debug a PVM application, TotalView becomes a PVM tasker so it can establish a debugging context for your session. You can run a TotalView PVM debugging session for a user and for an architecture; that is, different users can’t interfere with each other on the same computer or same computer architecture.
One user can start TotalView to debug the same PVM application on different computer architectures. However, a single user can’t have multiple instances of TotalView debugging the same PVM session on a single computer architecture.
