Hi,
 I was wondering if anyone on the list has a solution for my problem.
I'm keeping a number of files containing indices into a big (>2GB)
data file. I have a cocoa program that will read these index files and
fetch the appropriate data from the big file, plot it and store as an
image. I would like to run these print operations in parallel, but I'm
concerned that a conflict will arise if two threads are reading into
the same file. The index files are not disjoint, so a particular data
vector could be requested by several threads. Is there a way to handle
this in cocoa? The big file resides on a local network server and is
shared over nfs. Thanks!

~ Roger
