I haven't had trouble using the serial HDF5 library on NFS. For parallel HDF5, I believe there are certain versions of NFS and specific configurations required, and from what I understand it will certainly not be fast. I think you really need a file system that is built for parallel I/O to use parallel HDF5 effectively.
I don't know the answer regarding the requirement of flock().

Hi All, In case my previous question was lost between other issues I sent before, I'd like to ask again with hope someone knows the answer here: Is is possible to use HDF5 library on NFS filesystems where flock() is not possible? How to achieve this? Is there just some "switch" before compiling the library source? Regards, Rafal _______________________________________________ Hdf-forum is for HDF software users discussion.
