For Fortran and F90 debugging is - like all languages - inevitable. We look at debugging tips for Fortran and F90 developers to show why and how to use a debugger for some typical bugs.

Do it the right way, not the write way

The F90 and Fortran write…

This year we're proud to be sponsoring the Student Cluster Competition at SC15. One of the key codes teams will have to optimize for their systems is the classic Linpack benchmark. I decided to have a go on one of our test systems to see what the students…

What are dangling pointers?

Dangling pointers are pointers whose memory has been freed but which have not been set to null (or 0x0). This allows a particularly tricky class of bug to arise, because it is often possible for subsequent code to keep on using…
