Running OpenVMS VAX and ULTRIX RISC applications on Alpha

DECmigrate translates OpenVMS VAX and ULTRIX RISC applications into programs that run on Alpha! Regardless of the source language, you can run most user-mode, non-privileged applications on Alpha straight away – without disrupting your work environment and without waiting for the source code to be ported.

Two versions of DECmigrate are available:

DECmigrate for OpenVMS Alpha migrates OpenVMS VAX applications to OpenVMS Alpha. | See anonymous ftp instructions for downloading DECmigrate for OpenVMS Alpha.
DECmigrate for DIGITAL UNIX migrates ULTRIX RISC applications from MIPS to Compaq's Tru64 UNIX. | Click on mx.tar to download DECmigrate for DIGITAL UNIX.
The DECmigrate kits are offered free of charge for the convenience of our customers. No customer support is available. You must read and accept the DECmigrate license before downloading any DECmigrate files.

DECmigrate is a binary translator -- it converts a binary executable (that is, compiled) program for OpenVMS VAX or ULTRIX RISC on MIPS into a binary executable program optimized for OpenVMS Alpha or Compaq's Tru64 UNIX. To convert the code, DECmigrate works like a compiler: it uses the binary code for Alpha or MIPS as if it were source code and generates equivalent native Alpha binaries. The original and newly translated binaries are functionally the same, but the translated versions run faster, taking advantage of Alpha's superior performance.
