Checkpointing Figure 157: Create Checkpoint and Restart Checkpoint Dialog Boxes Checkpointing On SGI IRIX and IBM RS/6000 platforms, you can save the state of selected processes and then use this saved information to restart the processes from the position where they were saved. For more information, see the Process Window Tools > Create Checkpoint and Tools > Restart Checkpoint commands in the online Help. (See Figure 157.)

Figure 158: Tools > Debugger Loaded Libraries Dialog Box Fine-Tuning Shared Library Use Fine-Tuning Shared Library Use When TotalView encounters a reference to a shared library, it normally reads all of that library’s symbols. In some cases, you might need to explicitly read in this library’s information before TotalView automatically reads it. On the other hand, you may not want TotalView to read and process a library’s loader and debugging symbols. In most cases, reading these symbols occurs quickly. However, if your program uses large libraries, you can increase performance by telling TotalView not to read these symbols. For more information, see “Preloading Shared Libraries” on page 245 and “Controlling Which Symbols TotalView Reads” on page 246. Preloading Shared Libraries As your program executes, it can call the dlopen() function to access code contained in shared libraries. In some cases, you might need to do something from within TotalView that requires you to preload library information. For example, you might need to refer to one of a library’s functions in an eval point or in a Tools > Evaluate command. If you use the function’s name before TotalView reads the dynamic library, TotalView displays an error message. Use the Tools > Debugger Loaded Libraries command to tell the debugger to open a library. CLI: ddlopen This CLI command gives you additional ways to control how a library’s symbols are used. After selecting this command, TotalView displays the following dialog box: TotalView Users Guide: version 8.7 245
