hio.1.4.0.0-rc1

This release brings further optimizations to libhio. There are now three file modes that can be used: basic, file_per_node, and strided. No change was made to basic mode but optimized mode was split into two. The first writes all element data to a single file associated with all processes on the node. The second writes data blocks for each element across multiple files. file_per_node is valid for both unique and shared datasets but strided mode is only valid for shared datasets. The default mode for shared datasets is has been changed from basic to strided. No change was made to the default file mode for unique datasets.
