|
|
<h1 class="epydoc">Package MPI</h1><p class="nomargin-top"></p>
|
|
<p>Python interface to the Message Passing Interface (MPI)</p>
|
|
<p>This module contains a Python interface to the Message Passing
|
|
Interface (MPI), and standardized library for message-passing parallel
|
|
computing. Please read an introduction to MPI before using this module;
|
|
some terms in the documentation do not make much sense unless you
|
|
understand the principles of MPI.</p>
|
|
<p>This module contains an object, 'world', which represents the default
|
|
communicator in MPI. This communicator can be used directly for sending
|
|
and receiving data, or other communicators can be derived from it.</p>
|
|
<p>A number of global constants are also defined (<a
|
|
href="Scientific.MPI.max-class.html" class="link">max</a>, <a
|
|
href="Scientific.MPI.min-class.html" class="link">min</a>, <a
|
|
href="Scientific.MPI.prod-class.html" class="link">prod</a>, <a
|
|
href="Scientific.MPI.sum-class.html" class="link">sum</a>, <a

href="Scientific.MPI.bxor-class.html" class="link">bxor</a>, <a
|
|
href="Scientific.MPI.maxloc-class.html" class="link">maxloc</a>), and <a
|
|
href="Scientific.MPI.minloc-class.html" class="link">minloc</a>). They
|
|
are used to specify the desired operator in calls to the 'reduce' and
|
|
'allreduce' methods of the communicator objects.</p>
