An MPI profiler that just works, without slowing down your program.
Allinea MAP shows you which lines of code are slow and gets everything else out of your way.
No need to instrument your code or remember arcane libraries and settings. Allinea MAP just works, out of the box, whether at one process or ten thousand, with just 5% overhead.
Is the compiler vectorizing this loop correctly? Is this code CPU-bound, or memory-bound? Which MPI calls is it waiting at? Allinea MAP answers all these questions and more in a beautiful, intuitive GUI based on the industry-leading Allinea DDT.
