This is used to optimize virtual memory usage, allowing files to +be cached in memory so that they can be shared or accessed without going +to disk. It is also possible to conditionally access files via "direct +i/o", bypassing system virtual memory and transferring the data directly +from disk to or from process memory. + +NOTE: as of Dec 2001, the Vmcache library and vmcached have been updated +to provide the capabilites described above. The daemon runs, and was used +to develop the VM client interface, which is currently functional, tested, +and installed in os$zfiobf.c. The new version of the VMcache library +however, has not yet been fully tested and should not be used. + +Since this code is still under development it is not part of the normal +IRAF build (hence no mkpkg or mkpkg.sh). |
