Hi thanks for reply.<br><br>Actually i am trying to paralleling simple HAAR WAVELET.<br><br>In that i need to take summation and subtraction of two row/column out of an very large array(which represents an image) and is in N*N form with very large dimensions.<br>
<br>so what i want to do is pass two row/column to each worker process.<br>so in that part i am confused how to do that.<br><br>because i studied matrix multiplication but it just passes one row and a complete array to each worker.<br>
<br>i hope i mad it bit clear. and i am attaching serial algo here.<br><br>Thanks.<br><br>Anuj Patel<br><br><br><div class="gmail_quote">On Wed, Dec 2, 2009 at 8:50 PM, Dave Goodell <span dir="ltr"><<a href="mailto:goodell@mcs.anl.gov">goodell@mcs.anl.gov</a>></span> wrote:<br>

Can you elaborate a little bit? Are you trying to pass two rows and two columns of an array as an argument to a function? Is it in C or Fortran?<br>
<br>
Or do you mean how to send an MPI message containing the data from two rows and two columns of an array?<br>
<br>
