<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Hi everybody!<br>
<br>
A time ago I sent a email about an error reported on Visual Studio 2005
debugger. I was tring to debug an MPI application.<br>
<br>
That is a simple test, just to see what happens on each process.<br>
<br>
That's the code:<br>
<br>
// Somas parciais<br>
<br>
#include <mpi.h><br>
#include <stdio.h><br>
<br>
int main(int argc, char *argv[]){<br>
int soma = 0, s= 0, myid, numprocs, i, v[100];<br>
<br>
<br>
MPI_Init(&argc, &argv); <br>
MPI_Comm_rank (MPI_COMM_WORLD, &myid);<br>
MPI_Comm_size(MPI_COMM_WORLD, &numprocs);<br>
if(myid ==0)<br>
for(i = 0; i < 100; i++)<br>
v[i] = i+1;<br>
MPI_Bcast(v, 100, MPI_INT, 0, MPI_COMM_WORLD); <br>
soma = 0;<br>
<br>
for (i = myid; i< 100; i += numprocs )<br>
soma += v[i];<br>
<br>
printf ("Resultado parcial no processador: %d = %d
\n", myid, soma); <br>
MPI_Reduce(&soma, &s, 1, MPI_INT, MPI_SUM, 0,
MPI_COMM_WORLD); <br>
if(myid == 0)<br>
printf("Soma final = %d\n", s);<br>
MPI_Finalize();<br>
return(0);<br>
}<br clear=all>
<br>
It returns the addition of 100 numbers. The charge is shared equally on each process.
<br>
<br>
But when I try debbug that, the console returns:<br>
<br>
soma.exe on 'bruno' failed, error 5 - Access Denied.<br>
<br>
Windows do not permit Visual Studio create process.<br>
<br>
Anybody has experimented the same error? <br>
<br>
Thanks!<br>
<br>
