Top 10 Porting Considerations… 1. Do a complete inventory of all 3rd party software products and HP OpenVMS layered products before you start your port. These may be required for development, QA, or production deployment. Ensure you know the status of each of these on OpenVMS I64 before you go too far in your port. 2. Make sure your application builds cleanly and runs on OpenVMS Alpha V7.3-1 (or greater) using the latest released compilers and development tools 3. Check for hardware architecture consistently in all source code and DCL command procedures 4. Have automated regression tests as much as possible and clearly documented manual regression tests where necessary 5. Document your build procedure / process 6. Read the Porting Guide and various Release Notes (Really do it!) 7. Update any Fortran 77 code to Fortran 90 8. Reduce / Recode / eliminate any Alpha Macro (Macro64 code) and PL/I 9. Where possible, use IEEE floating point 10. Have a working development / QA environment on OpenVMS Alpha near by so you can compare results easily between Alpha and Integrity systems. 11. Sit back and just... Re-compile, Re-Link, and run :-) 32 © Copyright 2012 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice.
