[Pvfs2-users] How to code with ROMIO

[wmaple at 126.com]

  Hi,

I have installed pvfs2 successfully on my system. My purpose is to gain high performence, with coding within MPI environment. But how can I specify the parameter of file name of  MPI_File_open(). If I specify the parameter in a direct manner, such as /mnt/pvfs2/filename, does it mean that kernel interface is used, and ROMIO is bypassed? Is there any documents on this topic? Thank you.
