Ok. I spoke to several people at Lustre and they say mmap() is implemented properly on Lustre and any application that uses mmap() should work. Is there a way to simulate a mmap() call (I am not an expert programmer). I would like to see if this is a legemit bug on MonetDB or Lustre. Would anyone like to help me with this?

MonetDB does pretty scary stuff with mmap so without studying Lustre I cannot say wheter it could work.
