In this assignment, you will write both serial and parallel programs to calculate the Sum using the following formula: Sum $=4(1)2+1=0$ You will write a serial C program $($Sum$\_$Serial.c$)$ to calculate the sum Sum and validate the correctness of your serial implementation. You will modify the serial program into two parallel programs, namely Sum$\_$MPI$\_$v$1.$c and Sum$\_$MPI$\_$v$2.$c$.$ In Sum$\_$MPI$\_$v$1.$c$,$ utilize only MPI point$-$to$-$point communication functions $($MPI$\_$Send and MPI$\_$Recv$)$ for message passing. In Sum$\_$MPI$\_2.$c$,$ implement your parallel solution using collective communication functions. Compile and execute these programs on magnolia HPC cluster to obtain the results. The user can specify n when executing your programs
