The Web integration of Java gives it excellent "network" classes and support for message passing.
|
| 2 |
Thus "Java plus message passing" form of parallel computing is actually somewhat easier than in Fortran or C.
|
| 3 |
Coarse grain parallelism very natural in Java
|
| 4 |
"Data Parallel" languages features are NOT in Java and have to be added (as a translator) of NPAC's HPJava to Java+Messaging just as HPF translates to Fortran plus message passing
|
| 5 |
Java has built in "threads" and a given Java Program can run multiple threads at a time
-
In Web use, allows one to process Image in one thread, HTML page in another etc.
|
| 6 |
Can be used to do more general parallel computing but only on shared memory computers
-
JavaVM (standard Java Runtime) does not support distributed memory systems
