[Lustre-discuss] Lustre and memory-mapped I/O

[Huang, Eric]

Does Lustre support memory mapped I/O and direct I/O? 

I am trying to run Nastran using Lustre but it always reported failure
to create a directory. Since Nastran does a lot of memory mapped I/O, I
was wondering if it was the cause. 

I guess a good question to ask is that does Lustre support all POSIX
file system operations?

Thanks a lot.
