+This is an experimental version of XPMEM based on a version provided by
+Cray and uploaded to https://code.google.com/p/xpmem. This version supports
+any kernel 3.12 and newer. Keep in mind there may be bugs and this version
+may cause kernel panics, code crashes, eat your cat, etc.
+
+XPMEM is a Linux kernel module that enables a process to map the
+memory of another process into its virtual address space. Source code
+can be obtained by cloning the Git repository, original Mercurial
+repository or by downloading a tarball from the link above.
+
+The XPMEM API has three main functions:
+
+xpmem_make()    
+xpmem_get()
+xpmem_attach()
+
+A process calls xpmem_make() to export a region of its virtual address
+space. Other processes can then attach to the region by calling
+xpmem_get() and xpmem_attach(). After a memory region is attached, it
+is accessed via direct loads and stores. This enables upper-level
+protocols such as MPI and SHMEM to perform single-copy address-space
+to address-space transfers, completely at user-level.
+
+Note, there is a limitation to the usage of an attached region. Any
+system call that will call get_user_pages() on the region from the
+non-owning process with get EFAULT. This include pthread mutexes
+and condition variable, and SYS V semaphores. We intend to address
+this limitation in a future release.
+
+XPMEM regions are free to have "holes" in them, meaning virtual memory
+regions that are not allocated. This makes XPMEM somewhat more
+flexible than mmap(). A process could, for example, export a region
+via XPMEM starting at address 0 and extending 4 GB. Accesses to
+allocated (valid) virtual addresses in this region proceed normally,
+and pages are mapped between address spaces on demand. A segfault will
+occur if the source process or any other process mapping the region
+tries to access an unallocated (invalid) virtual address in the
+region.
