Afternoon

Following my previous question about atime, we have noticed that atime is
not consistent across lustre?  Is this expected?

We wrote a few line piece of code which reads a byte from a file, waits
10s and reads another byte etc.  Locally, the atime gets updated after
each byte read.  However, on other nodes, the atime is not updated.  Even
after the file has been closed, the atime on other nodes is still at
ctime.  We notice it can take quite a long time for the atime's to be
consistent across the cluster.

Is this expected?  The reason I ask is that we have an application which
is sensitive to atime changes and it is running really really slowely.

Thanks
Stu.
