But my first problem is with the execution. <br>I try execute the code using mpiexec, but never find the library mpi.h. I start with a simple code:<br><br>
#include <stdio.h><br>#include <mpi.h><br><br>int main(int argc, char **argv){<br> <br> int t;<br> t = MPI_Init(&argc,&argv);<br> if(t == MPI_SUCCESS){<br> printf("test ok");<br>
}<br> MPI_Finalize();<br> return 0;<br>}<br><br><br><br><br>So, I compiled with mpicc test.c -o test. The result was the executable, but it isn't work. The mensage no such file or directory.<br>I need some help.<br>
<br>thank you<br>
