[FLASH-USERS] Parallel I/O on Stampede

Hello,

Has anyone been able to run FLASH4 on Stampede with parallel I/O?

My code successfully compiles after setup with flag +hdf5typeio and 
loading module phdf5.  I restart from a checkpoint file written in 
serial, but it seems that not all grid variables/data from the input 
file are transferred to memory.

Thanks,
Meghann

Some screen output:
