Mathematical CUDA App for Pi

Accelerated Computing CUDA CUDA Programming and Performance

Is it possible to develop a mathematical application built on CUDA to calculate pi? If so, are there developers that specialize in CUDA coding?

2

One could certainly compute pi using CUDA. And, yes, there are developers that specialize in CUDA, although I don’t see what that has to do with computing pi.

3

Well, I’m basically trying to find a developer who can create a pi-calculating program for me based on CUDA. I wanted to know if calculating pi is something that CUDA is capable of doing. Would you happen to know a site where one can find CUDA developers? :)

Well, there’s the CUDA employment forum:

Just what I was looking for. Thanks! =)

not the best algo but easy

it s give pi/2

Sub a()

Const taille = 5  '<--- change

Dim ta1(taille) As Long

For i = 1 To taille

   ta1(i) = 0

Next i

ta1(1) = 1

For i = taille * 11 To 1 Step -1

For j = taille To 1 Step -1

      ta1(j) = ta1(j) * i + reste

      reste = 0

      If ta1(j) > 10000 Then

         reste = Int(ta1(j) / 10000)

         ta1(j) = ta1(j) - reste * 10000

      End If

   Next j

reste = 0

   For j = 1 To taille

      reste2 = (ta1(j) + reste * 10000) Mod (2 * i + 1)

      ta1(j) = Int((reste * 10000 + ta1(j)) / (2 * i + 1))

      reste = reste2

   Next j

ta1(1) = ta1(1) + 1

reste = 0

Next i

For i = 1 To taille

 Cells(i, 1) = ta1(i)

Next i

End Sub

Thank you! I just have one question now… How do I get this to calculate pi? I see this is an algorithm, so how do I get this into an application? Would it still be best for me to hire a developer?

OK, I’m kind of curious, if you don’t mind my asking. Why do you want to hire a developer to write a CUDA program to calculate pi? :)

If this is just for fun, a monte carlo algorithm will probably be the easiest.

I’m working on a project (super top-secret) and I need to calculate 50M digits of pi. External Image

No, really… I seriously need to calculate that. And I seriously need 50M digits.

Find the first billion digits for download here: http://stuff.mit.edu/afs/sipb/contrib/pi/pi-billion.txt

if you need only 50m try that

50M in 189 seconde without cuda :)

and the new version best of best in world
