Write an MPI C program to solve the hotplate problem. Because MPI

programs are executed via mpiexec, there will necessarily be a small

change to the method by which programs are run.

BE SURE THAT EVERY RANK DOES THIS:

alarm$(180)$

where $180$ is a sufficient number of seconds for the rank to do its work.

To run the program I will type commands like this one:

mpiexec $-$n $16./$l$45006001001001004000\mathrm{.}01$

where the $16$ represents the number of ranks to use.

Rank $0$ should act as a manager process here. It will coordinate the

activities of the other ranks. For that reason, you may assume that the

number of ranks specified will never be less than $2.$ Rank $0$ should also

produce all printed output.

Submit a zip file containing all of your project files,

including a makefile that will build the executable program which MUST

be named l$4.$ Note that I only type the simple command "make" below in

order to have the program built.

rm $-$rf l$4$

rm $-$f $*.$o

make
