Can anyone tell me where I can find a list of different parallel algorithms (or source codes) for matrix multiplication ?

Thanks ozo. But is there a site which explains several algorithms?
I'm actually looking for recursive ones, but it seems like there are not many in the web.

How about Strassen's Method?  
Is there a particular parallel architecture you want to run on?

I would be coding the algo in mpi, and would like to look for a few parallel recursive methods to evaluate.
I've thought of a simple tree-structured one, which divides the matrix into 3 sets of rows, 2 for the children and one to self-compute. But then again, it needs further improvement.

Take a look into http://www.cs.sandia.gov/~bahendr/lin_alg.html

There you will find asome papers dealing on linear algebra and
parallel algorithms....

Thanks Taliesin, but the papers do not exactly fit my requirements, nonetheless, they help.

How about this ones?

1) A Three-dimensional Approach to Parallel Matrix Multiplication by R. C. Agarwal, S. M. Balle, F. G. Gustavson, M. Joshi, and P. Palkar.
 Implementation of a 3D algorithm on an IBM SP2. :

      http://www.almaden.ibm.com/journal/rd/agarw/agarw.html
(with nice references!)


2) A Scalable Parallel Strassen's Matrix Multiply Algorithm
for Distributed Memory Computers by Qingshan Luo and John B. Drake.
 Parallel algorithm and implementation on 128-processor Intel iPSC. :
      http://www.epm.ornl.gov/~bbd/pubs/stras5.ps

3) Numerical algorithms for supercomputers:
    http://www.math.ruu.nl/people/bisselin/nas.html

  My choice is N°1, Strassen method, modified by Winograd, and
working as 3D matrices, not 2D....

   pretty cool ... ;)

Thanks. I've yet to take a look at the 3D algo (the page couldn't load up). Anyway, I've collected some links too in http://www.iscs.nus.edu.sg/~ngweikai/hon/ic4211/mpi. For your pleasure. It's not very broad.
