I am trying to decide which parallel debugger to use.
So far I found not many open sources ones so my choices are:
Which one do you recommend?
Are there anything else worthwhile?
A colleague wrote a few years ago a short technical report comparing the two. Moral of the story: they’re comparable, and the fact that there’s competition in the market has improved the landscape considerably. We use DDT now; I prefer the interface, and it now scales to much larger process counts than totalview does (but I suspect totalview will make up the difference shortly). DDT also works on all our machines (x86, CUDA, Power); check to see if Totalview can cover all your platforms.
