Programming

1. "Explicit concurrent tasks" model

	Dedicated object	Language primitive	Grammar extensions
CC++	.	.	par{}, parfor{}, spawn
DC++	Instance of DcThread	.	.
DoPVM	.	initiate()	.
Mercury	Instance of Thread	.	.
Presto	Instance of Thread	.	.

2. "Data oriented" model

	Features
C**	Parallel member function defined by user
Composites	Group functions
Dome	Templates
DPC++	Parallel types
Mentat	Data-flow approach
pC++	Parallel member function defined by user
QPC++	Broadcasting for a group

3. "Active objects" model

	Active Object Creation	Communication Between Active Objects	Granularity
Arjuna	Stub mechanism	Member function call Synchronous(RPC)	A
Avalon/C++	Standard C++	Member function call Synchronous	.
Charm++	new_chare()	Explicit message passing Asynchronous	A
Concurrent C++	create	Member function call Synchronous or asynchronous	.
KAROS	Standard C++	Member function call Asynchronous	.
LITP-C++	Standard C++	Member function call Synchronous or asynchronous	.
Open C++	Standard C++	Member function call Synchronous	A
Panda	Standard C++	Member function call Synchronous	B
QPC++	Standard C++	Member function call Synchronous or asynchronous	B
UC++	activenew	Member function call Asynchronous	A
µC++	Standard C++	Member function call Synchronous	B

A means 1 active object is mapped on 1 Unix process
B means More than 1 active object can be mapped on a Unix process and 1 or n lightweigth processes will be bounded to each active objects.
