hi
1 )I have a program to calculate log(2), in C.(using
SGI IRIX6.5) it requires the user to input the number
of terms in the series...
The statements are as follows
"
printf("Enter the number of terms ");
scanf("%d",&n);
"
I always find that after giving mpirun, the printf
statement never appears on the screen, the cursor
waits and once I enter a number, it goes on with the
execution. Ironically at the end of the WHOLE thing, a
small "Enter the number of terms" message appears...IS
this non-interactiveness preventible...Sorry if the
question appears too trivial...Coming to the main
issue
2) Can I pass data from proc 0 like this
" for(k=0;k<9;k++)
MPI_Send(&array[k][0][0],10,MPI_FLOAT,1,11,MPI_COMM_WORLD)"
And the corresponding array being accepted in
processor 1 in a similar loop???
PLEASE HELP OUT someone..if loopwise sending is not
allowed, how do I efficiently maintain control over
the sent and recieved 3D arrays...
Thanks in advance for the replies ;-)
