I agree with the premise - C++ exceptions are not a good choice for signalling numerical errors in high-performance computing environments, where said errors can happen with some frequency. However, I do not agree with the conclusion - what is the difference between removing exceptions and simply not using them in your project? All compilers already let you compile code without exceptions and the product I work on compiles all numerical code that way. I don't see what benefit you expect to reap from changing the fundamental way C++ exceptions are implemented and work. At the high end, you want a custom error solution fit for your particular task, I don't think we can have a generic exception framework that will work for every high-performance computing project.
