Hello
I am trying to run
http://x10-lang.org/documentation/code-examples/small-examples.html?id=103example
with MPI, as follows:
*export X10_NPLACES=2
x10c++ **MontePiCluster.x10 -o montepiobj -O
mpirun -np 4 ./montepiobj 1000 2 4
*
Here ./montepiobj 1000 2 4 tells to run with 1000 guesses, at 2 places with
4 threads.
In the MontePiCluster.x10 file, I have just added one statement:
*Console.OUT.println(" I am running at "+ places + " places ");*
So, the output comes:
*I am running at 2 places
I am running at 2 places
The value of pi is 3.112
I am running at 2 places
The value of pi is 3.112
The value of pi is 3.112
I am running at 2 places
The value of pi is 3.112*
So, my expectation was that with *-np 4,* and* *X10*_*NPLACES=2*, *it will
make it 4*2 = 8 places; but what is happening right now is that same m1 is
being run at 4 mpi processors. How can we use the mpi processor so that
value of pi is calculated at 8 places (only then using MPI is of any use )
and not at 2 places, repeated at 4 processors.
I will be thankful for your answers.
Thanks and Regards
Sparsh Mittal
