Abstract: When displaying the caller stack of a distributed client/server program that uses Remote Procedure Calls (RPC), the user is provided the capability of viewing the RPC calls in the same manner as normal procedure calls. When a breakpoint is encountered in an RPC server program while using a debugger for distributed programs, the call stacks for the client and server program are appended together into a single distributed call stack. In the case of nested RPC calls (e.g. program A executes an RPC call to program B which executes an RPC call to C and so on) all of the call stacks are appended together in the order they were created. The distributed call stack may span many programs, threads of execution, and computing machines. The distributed call stack may be used to select a routine from the call stack when setting a context for a tool that displays program state information.
