L1_NORM
A program for the l1 norm of a vector

L1_NORM is a warmup exercise for our lab session on Monday.

I asked you to write a program, using OpenMP, that sets up a vector of dimension 1000 filled with random values, and computes the l1 norm sequentially and with OpenMP.

Source Code:

• l1_norm.c, the C source code.
• l1_norm.cc, the C++ source code.
• l1_norm.f, the FORTRAN77 source code.
• l1_norm.f90, the FORTRAN90 source code.
• l1_norm_laptop_output.txt, the output file from a laptop using 2 processors.
• l1_norm.sh, a script to run the program.
• l1_norm_hpc_output.txt, the output file from the FSU HPC system.
