Parallel programming example needed.
f#parallel

Hello,
I want to learn Parallel Programming using F#.
I need 3 programs: task1.fs, task2.fs and program.fs

Here is task1.fs:

1
2
3
4
5
6
7
8
9
10
11
12
13

#light
module task1
open System
open System.Threading
open System.Threading.Tasks
 
type taskA(name: string) = class
    let sayHello text1 =
       
printfn "%s" text1
       
Thread.Sleep(10000)
end


Here is task2.fs:

1
2
3
4
5
6
7
8
9
10
11
12
13

#light
module task2
open System
open System.Threading
open System.Threading.Tasks
 
type taskB(name: string) = class
    let sayGood text2 =
       
printfn "%s" text2
       
Thread.Sleep(10000)
end


In the program.fs, I want to starts 2 new tasks are wait
them to finish; one task is the instance for task1 with the parameter “Hello,
how are you?” sent to sayHello in the class definition of taskA; another task
is the instance for task2 with the parameter “Fine, thank you!” sent to sayGood
in the class definition of taskB.That is: I want run the both tasks from program.fs, one task says "Hello, how are you?", and another task says "Fine, thank you!".
However, due to lack of document for parallel programming
for F#, I can not figure this out.
Any help is greatly appreciated.
[
By the way, my current development environment is VS2010RC1.
Thanks,

Starting multiple tasks and then waiting for them all to finish is "fork-join parallelism", and can be written in F# using Async.Parallel. The code would be something like

1
2
3
4
5

let tasks = [
    async { return doTaskA("Hello") }
    async { return doTaskB("Fine") }
    ]
tasks |> Async.Parallel |> Async.RunSynchronously

See

or most any example you can find that uses "Async.Parallel" for examples.
