Prerequisites for Running the StarPlat Library

Ensure the following before attempting to run the StarPlat library on your MacOS:

1. Dependencies: Confirm that all necessary dependencies, with particular attention to MPI, are properly installed.
2. Directory Structure: The directory structure should be as specified, with the StarPlat binary and required files located within the /path/to/StarPlat/src directory.

Execution Steps

1. Navigate to the Source Directory: Open a terminal and execute:

   cd /path/to/StarPlat/src

2. Execute the Library: Run the StarPlat library using the command below:

   ./StarPlat -s -f ../graphcode/staticDSLCodes/sssp_dslV2 -b mpi

   The command arguments are as follows:

   • -s: [This flag's description will be added here.]
   • -f: Designates the DSL file; for this example, it is sssp_dslV2.
   • -b mpi: Sets the backend to MPI.

3. Verify the Output: Check for a .cc file generated in the directory where the StarPlat binary is located after successful execution.

Troubleshooting

If you encounter issues, consider the following solutions:

• Permission Denied: If you get bash: ./StarPlat: Permission denied, change the executable permissions by running:

  chmod a+x StarPlat

• Cannot Execute Binary File: A bash: ./StarPlat: cannot execute binary file error might indicate an architecture mismatch. Confirm that the Makefile has the correct settings for your system architecture. Verify the compiler path with which gcc.
• No Such File or Directory: If bash: ./StarPlat: No such file or directory is displayed, check that the binary path is correct and all necessary files are in their proper locations.
• Library Not Loaded: Should you encounter an error like dyld: Library not loaded: /path/to/library, you need to ensure that all the dynamic libraries required by StarPlat are installed, or adjust the DYLD_LIBRARY_PATH environment variable to include the path where the libraries reside.
• Unsupported Architecture: If you're on Apple Silicon and encounter architecture-related issues, try using arch -x86_64 ./StarPlat to run the binary under Rosetta 2, or recompile the library for ARM architecture.
