... The routine processing of STIS data in the calibration ``pipeline" requires an interrelated set of software tasks and databases developed and maintained by many groups at STScI. We present the systems-level design of this calibration pipeline from the perspective of the STIS instrument group at STScI. We describe the multiple interfaces to the pipeline processes that the STIS group works across in an effort to provide for the routine calibration of STIS data. ... For example, the STIS group: . ...

In Actor Prolog a resident is a special mechanism that helps processes to inspect state of other processes. A resident observes the state of a specified (target) process and if the state of the process changes (for instance, after message handling) it proves a specified predicate of the process. ... Work of the resident. ... Any change of the list of target processes or arguments of resident function results in activation of the resident and repeated collection of information in the target worlds. ...

... Forum: A tour of the Linux VFS . ... Inodes represent entities on disks: there's one (and only one) for each file, directory, symlink, device and FIFO on the filesystem. When a user process does an open() syscall, it does a couple of things: - it looks up the inode for the pathname - it puts the inode into the inode cache - it allocates a new file structure - it allocates a filedescriptor slot, and points it it at the file structure The number of the file descriptor slot is what is returned. ...

... The DAL is essentially implemented in C++. The design takes the form of a set of abstract classes which provides the fundamental DAL interface. There are currently two implementations (both in C++) of this abstract interface; one is the High Memory Model and the other is the HighLow Memory Model. ... In particular, an understanding of the C++ class hierarchy will lead to more generic algorithms e.g. use BlockT rather than ArrayT if only the BlockT methods are needed. Class Hierarchy . ...

. An operating system is the program that controls all the other parts of a computer system - both the hardware and the software. Most importantly, it allows you to make use of the facilities provided by the system. Every computer has an operating system.

Reference clock support maintains the fiction that the clock is actually an ordinary peer in the NTP tradition, but operating at a synthetic stratum of zero. ... The main interface used by these routines is the refclockproc structure, which contains for most drivers the decimal equivalents of the year, day, month, hour, second and millisecond/microsecond decoded from the ASCII timecode. ... In addition, there may be a driver-specific unit structure used for local control of the device. ...
