I see that you also emailed MPICH with the same question. I'll reply with more-or-less the same response: I am not a lawyer, and this is not legal advice, but Open MPI has a very permissive license (see the LICENSE file); you should be able to use it in your research without any letter of support from the Open MPI community.
Note, too, that this mailing list goes to several hundred people around the world. If you are looking for a letter for support to include in a funding proposal, you might want to be a bit more targeted and ask someone who is familiar with you and/or your specific work. You might also want to give them more than 1 day to respond. ________________________________ From: devel <devel-boun...@lists.open-mpi.org> on behalf of Diao, Xiaoxu via devel <devel@lists.open-mpi.org> Sent: Friday, October 6, 2023 11:44 AM To: devel@lists.open-mpi.org <devel@lists.open-mpi.org> Cc: Diao, Xiaoxu <diao...@osu.edu> Subject: [OMPI devel] Asking for a letter of support Dear Sir/Madam, My name is Xiaoxu Diao. I am a research associate at The Ohio State University. We are in the process of developing a proposal for an SBIR/STTR program. We are planning to use your library (Open MPI) in our application. Please let us know whom we should contact to obtain a formal letter of support indicating support for the use of your library during the Phase I development of our application. We would appreciate it if we could receive your response before 10/7/2023. Thank you. Best regards, Xiaoxu Diao
