Hi Dana, I installed HDF5 using the patch that you pointed me to and ran a test case. It looks like everything works. Thank you very much!

My current computing resources aren't sufficient for much longer, so I got an account on a new computing resource. Unfortunately, the administrators on this new system have disabled file locking to improve performance of their Lustre file system. HDF5 demands file locks, which I don't need, and I can't find a way to turn that off. Is there a way to tell HDF5 to not request a file lock, so that I can run on a system that doesn't allow file locking? Thank you, Brendan
