Definitely. dbg mode turns on the internal glibcxx checks, which
range from extremely slow (bounds checking on std::vector) to glacial
(some of the std::map checks change the asymptotic complexity IIRC).

The problem is that the error, (which shows up as a random NaN, or a sudden
jump in the residual, which does not s only occurs while running in parallel on
fairly large systems, after a few timesteps. Running a debug case will be
painfully slow.
I’ve a couple of questions.

If you can replicate the errors on a small problem, valgrind is usable
in parallel.

Hi,
Do you guys know of any free tools that help debug memory errors in parallel
code? Essentially a free version of total-view?
Thanks,
