can specify multiple executables. The first argument, <em>count</em>, indicates
the number of executables. The next three arguments are arrays of the
corresponding arguments in <a class="reference internal" href="MPI_Comm_spawn.3.html#mpi-comm-spawn"><span class="std std-ref">MPI_Comm_spawn</span></a>. The next argument,
<em>array_of_info</em>, is an array of <em>info</em> arguments, one for each
executable. See the INFO ARGUMENTS section for more information.</p>
<p>For the Fortran version of <em>array_of_argv</em>, the element
<em>array_of_argv</em>(i,j) is the jth argument to command number i.</p>
<p>In any language, an application may use the constant MPI_ARGVS_NULL
(which is likely to be <code class="docutils literal notranslate"><span class="pre">(char</span> <span class="pre">**)0</span></code> in C) to specify that no arguments
should be passed to any commands. The effect of setting individual
elements of <em>array_of_argv</em> to MPI_ARGV_NULL is not defined. To specify
arguments for some commands but not others, the commands without
arguments should have a corresponding <em>argv</em> whose first element is null
<code class="docutils literal notranslate"><span class="pre">((char</span> <span class="pre">*)0</span></code> in C and empty string in Fortran).</p>
<p>All of the spawned processes have the same MPI_COMM_WORLD. Their ranks
in MPI_COMM_WORLD correspond directly to the order in which the commands
are specified in <a class="reference internal" href="#mpi-comm-spawn-multiple"><span class="std std-ref">MPI_Comm_spawn_multiple</span></a>. Assume that m1 processes are
generated by the first command, m2 by the second, etc. The processes
corresponding to the first command have ranks 0, 1,…, m1-1. The
processes in the second command have ranks m1, m1+1, …, m1+m2-1. The
processes in the third have ranks m1+m2, m1+m2+1, …, m1+m2+m3-1, etc.</p>

<p><em>bool</em> info keys are actually strings but are evaluated as follows: if
the string value is a number, it is converted to an integer and cast to
a boolean (meaning that zero integers are false and non-zero values are
true). If the string value is (case-insensitive) “yes” or “true”, the
boolean is true. If the string value is (case-insensitive) “no” or
“false”, the boolean is false. All other string values are unrecognized,
and therefore false.</p>
<p>Note that if any of the info handles have <em>ompi_non_mpi</em> set to true,
then all info handles must have it set to true. If some are set to true,
but others are set to false (or are unset), MPI_ERR_INFO will be
returned.</p>
<p>Note that in “#PACKAGE_NAME#”, the first array location in
<em>array_of_info</em> is applied to all the commands in <em>array_of_commands</em>.</p>

<p>The argument <em>count</em> is interpreted by MPI only at the root, as is
<em>array_of_argv</em>. Since the leading dimension of <em>array_of_argv</em> is
<em>count</em>, a nonpositive value of <em>count</em> at a nonroot node could
theoretically cause a runtime bounds check error, even though
<em>array_of_argv</em> should be ignored by the subroutine. If this happens,
you should explicitly supply a reasonable value of <em>count</em> on the
nonroot nodes.</p>
<p>Similar to <a class="reference internal" href="MPI_Comm_spawn.3.html#mpi-comm-spawn"><span class="std std-ref">MPI_Comm_spawn</span></a>, it is the application’s responsibility to
terminate each individual set of argv in the <em>array_of_argv</em> argument.
In C, each argv array is terminated by a NULL pointer. In Fortran, each
argv array is terminated by an empty string (note that compilers will
not automatically insert this blank string; the application must ensure
to have enough space for an empty string entry as the last element of
the array).</p>
<p>Other restrictions apply to the <em>array_of_argv</em> parameter; see
<a class="reference internal" href="MPI_Comm_spawn.3.html#mpi-comm-spawn"><span class="std std-ref">MPI_Comm_spawn</span></a>’s description of the <em>argv</em> parameter for more
details.</p>
<p>MPI-3.1 implies (but does not directly state) that the argument
<em>array_of_commands</em> must be an array of strings of length <em>count</em>.
Unlike the <em>array_of_argv</em> parameter, <em>array_of_commands</em> does not need
to be terminated with a NULL pointer in C or a blank string in Fortran.
Older versions of Open MPI required that <em>array_of_commands</em> be
terminated with a blank string in Fortran; that is no longer required in
this version of Open MPI.</p>
<p>Calling <a class="reference internal" href="MPI_Comm_spawn.3.html#mpi-comm-spawn"><span class="std std-ref">MPI_Comm_spawn</span></a> many times would create many sets of children
with different MPI_COMM_WORLDs, whereas <a class="reference internal" href="#mpi-comm-spawn-multiple"><span class="std std-ref">MPI_Comm_spawn_multiple</span></a> creates
children with a single MPI_COMM_WORLD, so the two methods are not
completely equivalent. Also if you need to spawn multiple executables,
you may get better performance by using <a class="reference internal" href="#mpi-comm-spawn-multiple"><span class="std std-ref">MPI_Comm_spawn_multiple</span></a> instead
of calling <a class="reference internal" href="MPI_Comm_spawn.3.html#mpi-comm-spawn"><span class="std std-ref">MPI_Comm_spawn</span></a> several times.</p>

<div class="section" id="errors">
<h2><span class="section-number">17.2.78.7. </span>ERRORS<a class="headerlink" href="#errors" title="Permalink to this heading"></a></h2>
<p>Almost all MPI routines return an error value; C routines as the return result
of the function and Fortran routines in the last argument.</p>
<p>Before the error value is returned, the current MPI error handler associated
with the communication object (e.g., communicator, window, file) is called.
If no communication object is associated with the MPI call, then the call is
considered attached to MPI_COMM_SELF and will call the associated MPI error
handler. When MPI_COMM_SELF is not initialized (i.e., before
<a class="reference internal" href="MPI_Init.3.html#mpi-init"><span class="std std-ref">MPI_Init</span></a>/<a class="reference internal" href="MPI_Init_thread.3.html#mpi-init-thread"><span class="std std-ref">MPI_Init_thread</span></a>, after <a class="reference internal" href="MPI_Finalize.3.html#mpi-finalize"><span class="std std-ref">MPI_Finalize</span></a>, or when using the Sessions
Model exclusively) the error raises the initial error handler. The initial
error handler can be changed by calling <a class="reference internal" href="MPI_Comm_set_errhandler.3.html#mpi-comm-set-errhandler"><span class="std std-ref">MPI_Comm_set_errhandler</span></a> on
MPI_COMM_SELF when using the World model, or the mpi_initial_errhandler CLI
argument to mpiexec or info key to <a class="reference internal" href="MPI_Comm_spawn.3.html#mpi-comm-spawn"><span class="std std-ref">MPI_Comm_spawn</span></a>/<a class="reference internal" href="#mpi-comm-spawn-multiple"><span class="std std-ref">MPI_Comm_spawn_multiple</span></a>.
If no other appropriate error handler has been set, then the MPI_ERRORS_RETURN
error handler is called for MPI I/O functions and the MPI_ERRORS_ABORT error
handler is called for all other MPI functions.</p>
<p>Open MPI includes three predefined error handlers that can be used:</p>
<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">MPI_ERRORS_ARE_FATAL</span></code>
Causes the program to abort all connected MPI processes.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">MPI_ERRORS_ABORT</span></code>
An error handler that can be invoked on a communicator,
window, file, or session. When called on a communicator, it
acts as if <a class="reference internal" href="MPI_Abort.3.html#mpi-abort"><span class="std std-ref">MPI_Abort</span></a> was called on that communicator. If
called on a window or file, acts as if <a class="reference internal" href="MPI_Abort.3.html#mpi-abort"><span class="std std-ref">MPI_Abort</span></a> was called
on a communicator containing the group of processes in the
corresponding window or file. If called on a session,
aborts only the local process.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">MPI_ERRORS_RETURN</span></code>
Returns an error code to the application.</p></li>
</ul>
<p>MPI applications can also implement their own error handlers by calling:</p>
<ul class="simple">
<li><p><a class="reference internal" href="MPI_Comm_create_errhandler.3.html#mpi-comm-create-errhandler"><span class="std std-ref">MPI_Comm_create_errhandler</span></a> then <a class="reference internal" href="MPI_Comm_set_errhandler.3.html#mpi-comm-set-errhandler"><span class="std std-ref">MPI_Comm_set_errhandler</span></a></p></li>
<li><p><a class="reference internal" href="MPI_File_create_errhandler.3.html#mpi-file-create-errhandler"><span class="std std-ref">MPI_File_create_errhandler</span></a> then <a class="reference internal" href="MPI_File_set_errhandler.3.html#mpi-file-set-errhandler"><span class="std std-ref">MPI_File_set_errhandler</span></a></p></li>
<li><p><a class="reference internal" href="MPI_Session_create_errhandler.3.html#mpi-session-create-errhandler"><span class="std std-ref">MPI_Session_create_errhandler</span></a> then <a class="reference internal" href="MPI_Session_set_errhandler.3.html#mpi-session-set-errhandler"><span class="std std-ref">MPI_Session_set_errhandler</span></a> or at <a class="reference internal" href="MPI_Session_init.3.html#mpi-session-init"><span class="std std-ref">MPI_Session_init</span></a></p></li>
<li><p><a class="reference internal" href="MPI_Win_create_errhandler.3.html#mpi-win-create-errhandler"><span class="std std-ref">MPI_Win_create_errhandler</span></a> then <a class="reference internal" href="MPI_Win_set_errhandler.3.html#mpi-win-set-errhandler"><span class="std std-ref">MPI_Win_set_errhandler</span></a></p></li>
</ul>

an error.</p>
