You'd need to send debug logs for the paralle engine for us to have
any hint at what the problem may be. Those would be located on the
remote computer, probably in your home directory, when you run with
This sounds like an out of memory type of crash but I didn't see any
obvious leaks in the VTK reader's code and I'd be very surprised if
there were any in there by now. This doesn't mean there can't be
leaks in some other places though.
1. Which version of VisIt?
2. Are you just doing a movie of your entropy variable
3. How is that variable stored in the VTK file? float?
4. How large is your mesh? I'm assuming it's 1 domain since you're
using VTK. If it's 1 domain, you won't see any parallel benefits.
