Using PVM

Using PVM

PVM is a software system that enables a collection of heterogeneous computers to be used as a coherent and flexible concurrent computational resource.

The individual computers may be shared- or local-memory multiprocessors, vector supercomputers, specialized graphics engines, or scalar workstations, that may be interconnected by a variety of networks, such as ethernet, FDDI.

User programs written in C, C++ or Fortran access PVM through library routines.

Setting Local Environment

Add the following lines to ~/.cshrc

	setenv PVM_ROOT /usr/local/pvm3
	setenv PVM_ARCH SUN4SOL2
	set path=($path /usr/local/pvm3/lib)

Sample Hello Programs

Make a directory call examples and put the following files in it.

Compile Sample Hello Programs

Use the following command to compile the sample program. After compilation, it will create a directory call SUN4SOL2 and put the executables there.

 	aimk hello hello_other

Running Sample Hello Program

To run the sample hello program from a shell prompt
```
	cd SUN4SOL2
	./hello
```
To run the sample hello program from the pvm console
```
	cd SUN4SOL2
	pvm
	spawn -> hello
```

Here's a sample output:

	i'm t40012
	from t40013: hello, world from turing
