INSTRUCTIONS FOR RUNNING PROGRAM


run in terminal 
for general running, this will run with input size 5 workers 3, so if you want more, then run below
make
make run 


for specififying input and workers, run in terminal
make
make run n=(replace with a number) m=(replace with a number) input=input.txt output=output.dat



-------------------------------------------------
gcc my-sum.cpp -o my-sum -lm
./my-sum n m input.dat output.dat
-------------------------------------------------

put n > m and > 0 in place of n and m



---------------------------
More details ( can skip)

TO RUN IN SCHOOL SERVER
ssh netid@cs1.utdallas.edu
then enter password...


nano my-sum.cpp 
then paste in code from vscode

make sure their is an input file as well! input.dat is what was given

then in terminal, to run program, run
-------------------------------------------------
gcc my-sum.cpp -o my-sum -lm
./my-sum n m input.dat output.dat
-------------------------------------------------
for the command above, make sure that you replace n and m with numbers.
n is for the number in your input file
m is for the number of worker
and n >= m
also, make sure that the input.dat matches the name of the input file that you have. 

baam : output data should run

------------------------------------------------------------------------------------------------------------------
to check program
this will print out first 10 of both files
paste <(head -n 10 input.txt | tr ' ' '\n') <(head -n 10 output.dat) | awk '{print "Input:", $1, "Output:", $2}'

given input.txt not input.dat, if you want to run on input.dat just change input.txt to input.dat


paste this in termial to check if sumof entire input file == to last in output file, in the command, it says second to last because technically last is just newline

input_sum=$(awk '{for(i=1;i<=NF;i++) sum+=$i} END{print sum}' input.txt)
echo "Input sum: $input_sum"
output_last=$(tail -n 2 output.dat | head -n 1)
echo "Last output: $output_last"
