No, he's not "our" Vasily :). I thought it was also until today. He had the build issues last week - I thought this was "our" Vasily also, that's why I responded! I'm in Israel now and just spoke with Vasily; he was confused as to why I was emailing him about SVN problems.

I'll have to look into that. It looks like with all my humble patches it should compile and pass the tests successfully even if compiled with -march=native -mtune=native -Ofast+ optimization, and all the perks enabled. That is, if the missing headers will be made available.
No, I haven't been contacted by Mellanox nor by any respectful organization mentioned on the OMPI membership list to support Open MPI under Cygwin 32/64-bit. Even if I have a degree in Physics, invested a personal fortune in my Quantitative..., in my second-third degree studies in Switzerland, and have 20+ years of work experience in the IT field, quite recently with the Brutus cluster, who would be willing to look for a new hire nowadays?
