random roundoff?
On my CentOS 5 box, in a C++ program that does much arithmetic, including numerous matrix multiplications, I have a situation in in which the result depends on the nature of nearby I/O. Thus, with all arithmetic done with type double, and where values are mostly in the range [-1.0e0,+1.0e0] or nearby, I do: cerr << "some stuff" << endl; mat3 = matmult(mat1,mat2);

Adapting and open-sourcing PGI's Fortran frontend for LLVM
...can comment on a specific issue - When we ported our Fortran front-end to target llvm, we found that Fortran ENTRY doesn't map very well to llvm ir.

No closed doors intended here. Just a recognition that for something like an initial review to be useful, we probably have to be a bit careful in how many people we can reasonably involve before it could get unwieldy, and trying to be respectful of people’s time if we can nail down 90% of issues with a smaller group before going broader. I think we’d be fine with opening up the WebEx presentations
