	Categorical list of programming languages Summary
		In a procedural programming language, the programmer defines the set of executable instructions and the exact sequence in which those instructions are to be executed.
		Declarative programming stands in contrast to imperative programming via imperative programming languages, where serial orders (imperatives) are given to a computer.
		Procedural programming languages are based on the concept of the unit and scope (the data viewing range of an executable code statement).

	ZPL (programming language) - Wikipedia, the free encyclopedia
		ZPL (short for Z-level Programming Language) is an array programming language designed to replace C and C++ programming languages in engineering and scientific applications.
		ZPL is translated into a conventional abstract syntax tree representation on which program analysis and program optimizations are performed.
		This C program (which is machine independent because it implements certain operations in abstract form) is then compiled using the native C compiler on the target machine with custom libraries optimized to the specific platform.

		With its emphasis on program safety, it is not surprising that Ada is a strongly typed language: all data elements must be declared as storing a particular type or subtype, and type enforcement is strictly applied both within and between modules.
		Curry is a fairly recent functional logic programming language, developed as a research vehicle to test ideas in the areas of narrowing, unification, and non-determinism.
		The basic view of programming exhibited by Escher and related languages is the a program is a representation of a theory in some logic framework, and the program's execution (computation) is a deduction from the theory.

	ZPL
		ZPL compiles to ANSI C, which is then compiled with a machine-specific library to the target machine.
		ZPL is presently targeted to the Cray T3E, IBM SP2, Intel Paragon, SGI Origin, Sun Enterprise, High-performance clusters, and UNIX workstations.
		ZPL is in use at supercomputer centers including the Arctic Region Supercomputing Center, Los Alamos National Lab, and the Maui High-Performance Computing Center.

		This allows one to write programs that are able to cover a variety of input, instead of being limited to a small number of cases.
		Since programming languages are artificial languages, they require a high degree of discipline to accurately specify which operations are desired.
		Programming languages are not error tolerant; however, the burden of recognizing and using the special vocabulary is reduced by help messages generated by the programming language implementation.

	Overview
		ZPL is an array programming language designed from first principles for fast execution on both sequential and parallel computers.
		Because ZPL compiles to ANSI C with calls to the user's choice of communication library (including MPI), ZPL is highly portable.
		If a ZPL program is to be run using MPI, then the ZPL libraries for MPI would perform the marshaling; on a machine with efficient RDMA, no marshaling would be performed.

	Programming Languages Proposal for Curriculum 2001
		Language translation understood conceptually as an implementation on a virtual machine, followed by a sequence of translations to simpler core languages through a hierarchy of virtual computers.
		The student should be made aware of how the syntax of a programming language is formally specified, thus enabling the programming language designer to communicate the language syntax to the users and language implementers.
		With the advent of the first truly popular garbage collected language, Java, it is increasingly important for the student to understand the implementation issues and program correctness issues (explicit vs. automatic allocation/deallocation) involved in choosing a language based on a particular memory allocation/deallocation model.

		Programming languages written for serial computers abstract out inconvenient details about the host machine in order to allow programmers to concentrate on solving general problems.
		Programs written at the Z level are both portable and scalable, since they embed no information about a particular parallel architecture or problem size.
		The ZPL programming language, developed at the University of Washington, provides programmers with a language for implementing data parallel algorithms at the Z level.

	Explicit Implications of Cluster Computing \| Linux Magazine
		ZPL is an array programming language designed to replace common programming languages used in engineering and scientific applications.
		Declarative programming (http://en.wikipedia.org/wiki/Declarative_programming/), on the other hand, allows the program to say what is to be done, but does not say how.
		The ZPL language is great example of this method, because the programmer doesn’t express “how” to solve a matrix operation, but describes what he or she wants to do, allowing the compiler to optimize for a particular environment.

		This article is about the zpl dy command complexity class.
		In complexity theory, ZPL (Zero-error zpl file to loftware Probabilistic Logarithmic space) is the set of problems solvable by a probabilistic Turing machine which always yields the correct answer and uses logarithmic space on average.
		A surprising result is that ZPL is equal to both RL and NL; thus, if a problem can be solved in logarithmic space with nondeterminism or with one-sided error, it can be solved with no error and logarithmic space on average.

	Caps: ZPL for the Mercury-RACE and RACE++ (Site not responding. Last check: 2007-10-20)
		The RACE is usually programmed in C and therefore the user must insert appropriate communication and synchronization calls to enable concurrency.
		The inherent difficulty of parallel programming combined with the complexity of the hardware makes programming the RACE a very involved process, and often requires special training or very long development time.
		Using ZPL, a programmer would be able to write a high performance embedded application in very short development time and with the additional benefit of 100% portability across a wide spectrum of parallel and sequential platforms.

	Alumni Newsletter Summer 2000
		As a graduate student, Lewis developed "Advanced ZPL," a programming language that enables computers to perform enormous computations, such as those used to forecast the weather or to test nuclear weapons.
		"You want a programming language to be reasonably easy for humans to use but at same time you want some kind of implementation system like a compiler to convert it into something the machine can understand.
		Lewis encourages his students to draw on their individual skills to strengthen the group-one student, for example, might be strong in graphics while another may be working on visual programming languages.

		ZPL is a high-level parallel programming language for supercomputers under development at the University of Washington.
		ZPL now offers a middle ground—programmers are saved from having to write their own checkpointing code, and the compiler can optimize the checkpointing by ignoring dead data.
		This is possible due to the high-level nature of ZPL and the versatility of its runtime structures, but there are a number of interesting analysis problems this poses.

		In a vector language, operations are done on entire collections of data, avoiding loops.
		Lately I've been converting the UI toolkit to use this library where it simplifies code, and I have noticed that a lot of operations can be expressed in a very natural manner using this library.
		While the resulting code is not as compact as in a dedicated vector language, the vector language idioms map remarkably well to Factor.

		Although transactions have great potential for simplifying multithreaded programming due to their strong atomicity guarantees, this work shows that these same guarantees can have unexpected and potentially serious negative effects on programs that were written assuming weaker synchronization primitives.
		ZPL is a high-level language that offers competitive performance and portability, as well as programming convenience lacking in low-level approaches.
		The results show that for eight programs from a number of standard benchmark suites, ZPL generally outperforms HPF, and ZPL expresses problems at higher levels of abstraction, yielding programs that are shorter, less error prone and easier to maintain.
