I would like to add Mellanox to the list of organizations that support this letter. Pasha. Richard Treumann wrote:
All -
The signatories of this letter represent the majority of MPI implementors participating in the MPI Forum. We are concerned that proposal #140 ("Add const Keyword to the C bindings") has a number of issues which suggest delaying to MPI-3 would be appropriate.
In particular, the proposal:
- Is likely to pass a simple majority vote, but does not carry the support of the majority of MPI implementors, suggesting consensus has not been reached. - Changes 90+ MPI API interfaces, which is not a "trivial" change and therefore does not meet the intent of the MPI-2.2 process. - Is not needed to fix any serious bug in the standard text or to solve an issue that cannot easily be avoided by the MPI application. - Does not offer any demonstrable optimization opportunities for implementation or application, but may constrain future implementation opportunities.
Therefore, we ask for your assistance in deferring proposal #140 to the MPI-3 process, where more time can be spent assessing its impact.
Thank you,
