Now that Version 2.0 is released, can I still make submissions with the Version 1.1 or Version 1.0?
The changes in MPI2007 Version 2.0 are primarily to support the large data suite; you are still allowed to use Version 1.1 submit results for the medium suite. The SPEC/HPG committee makes this exception so that non-SPEC/HPG members who purchased the medium suite are not required to buy the Version 2.0 update unless they plan to run the large data benchmarks. Since Version 2.0 contains changes to the tools, SPEC/HPG members are encouraged to use Version 2.0 to ensure that the new tools are being tested as much as possible. Future changes to the MPI2007 benchmarks or tools may require that all users move up to the latest version. For example, Version 1.0 has not been allowed to be used for submissions since Version 1.1 came available. If you are in a position where you could make valid runs with Version 1.0 but not Version 1.1 or Version 2.0, the SPEC HPG needs to be notified.
