-- [10 marks] Write a C program to perform parallel matrix multiplication using OpenMP. You should first create three matrices A, B, and C then initialize A and B to some values of your choice (e.g., a[i][j]=i+j and b[i][j]=i*j+1). Then, perform parallel matrix multiplication, and finally print out the result matrix C. In your code, try to improve the performance by (re)using the same set of threads for initializing A and B and for calculating C. Search online for information about how to do matrix multiplication, e.g., here. Include the following C statements near the beginning of your program (you may change the numbers). #define NRA 20 /* number of rows in A */ #define NCA 30 /* number of columns in A = number of rows in B */ #define NCB 10 /* number of columns in matrix B */
