Package edu.rit.pj.reduction Description

Package edu.rit.pj.reduction contains classes for parallel reduction.

Class Op is the abstract base class for a binary operation used to combine two values together during a reduction. The subclasses of class Op provide binary operations on different data types:

Type Class
boolean BooleanOp
byte ByteOp
char CharacterOp
double DoubleOp
float FloatOp
int IntegerOp
long LongOp
short ShortOp
Object ObjectOp

Each of these subclasses provides an op() method that can be overridden to compute the desired binary operation. Each of these subclasses also provides static instances for commonly-used binary operations like sum, product, maximum, and minimum.

The following classes provide shared reduction variables for each of the primitive types as well as type Object. These classes are intended to be used in an SMP parallel program for data items shared among all the threads in the program.

Type Class
boolean SharedBoolean
byte SharedByte
char SharedCharacter
double SharedDouble
float SharedFloat
int SharedInteger
long SharedLong
short SharedShort
Object SharedObject

The following classes provide shared reduction variables for arrays of each of the primitive types as well as array of type Object. These classes are intended to be used in an SMP parallel program for data arrays shared among all the threads in the program.

Type Class
boolean[] SharedBooleanArray
byte[] SharedByteArray
char[] SharedCharacterArray
double[] SharedDoubleArray
float[] SharedFloatArray
int[] SharedIntegerArray
long[] SharedLongArray
short[] SharedShortArray
Object[] SharedObjectArray
