Rice winnowing, Uttarakhand, India Winnowing in a village in Tamil Nadu, India Use of winnowing forks by ancient Egyptian agriculturalists. Winnowing is a process by which chaff is separated from grain. It can also be used to remove pests from stored grain. Winnowing usually follows threshing in grain preparation. In its simplest form, it ...
The target platform of Java's bytecode compiler is the Java platform, and the bytecode is either interpreted or compiled into machine code by the JVM. Other compilers almost always target a specific hardware and software platform, producing machine code that will stay virtually unchanged during execution [ citation needed ] .
Dynamic compilation is a process used by some programming language implementations to gain performance during program execution. Although the technique originated in Smalltalk , [ 1 ] the best-known language that uses this technique is Java .
On 13 November 2006, Sun's HotSpot Java virtual machine (JVM) and Java Development Kit (JDK) were made available [4] under the GPL license. [5]Since version 0.95, GNU Classpath, a free implementation of the Java Class Library, supports compiling and running javac using the Classpath runtime — GNU Interpreter for Java (GIJ) — and compiler — GNU Compiler for Java (GCJ) — and also allows ...
Whole program optimization (WPO) is the compiler optimization of a program using information about all the modules in the program. Normally, optimizations are performed on a per module, "compiland", basis; but this approach, while easier to write and test and less demanding of resources during the compilation itself, does not allow certainty about the safety of a number of optimizations such ...
A Java compiler is a compiler for the Java programming language. Some Java compilers output optimized machine code for a particular hardware/operating system combination, called a domain specific computer system. An example would be the now discontinued GNU Compiler for Java. [1]
When code generation occurs at runtime, as in just-in-time compilation (JIT), it is important that the entire process be efficient with respect to space and time. For example, when regular expressions are interpreted and used to generate code at runtime, a non-deterministic finite-state machine is often generated instead of a deterministic one, because usually the former can be created more ...
In sedimentology, winnowing is the natural removal of fine material from a coarser sediment by wind or flowing water. Once a sediment has been deposited, subsequent changes in the speed or direction of wind or water flowing over it can agitate the grains in the sediment and allow the preferential removal of the finer grains.
