[FLASH-USERS] some problem when setting 'restart'

[Aaron Tran]

Hi Zhang,

FLASH reads the restart checkpoint file from the path specified by runtime
parameter "output_directory".  If that parameter isn't set, FLASH will try
to read the checkpoint from the current working directory (wherever you
called the flash executable from).  It looks like FLASH is doing the
latter, based on your error message.

Best,
Aaron
