Please do it in c++,c# or java.It should use multithreading
concept.
In this lab, you will implement a multithreaded sum application
in a language that supports parallelism (not Python). Your program
will sum up all the numbers from 1 to 500,000,000. The result
should be 125,000,000,250,000,000. You should define a function for
each of the following approaches. Each function should be timed so
that you can print out how long the operation took. Approach 1:
Single threaded sum Approach 2: Multithreaded sum. For this
approach, you should test with a variable number of threads ranging
from 2 to (at least) 10. The work should be split in numerical
order. For example, if you have 2 threads, thread 1 should sum up
the first half of the numbers and thread 2 should handle the second
half. Approach 3: Balanced multithreaded sum. For this approach,
you should test with a variable number of threads ranging from 2 to
(at least) 10. The work should be split in numerical order. For
example, if you have 2 threads, thread 1 should sum up the odd
numbers and thread 2 should handle the evens. With 3 threads,
thread 1 would handle 1, 4, 7, ..., thread 2 would handle 2, 5, 8,
..., and thread 3 would handle 3, 6, 9, ..., etc.
Please give your CPU and the number of cores + threads.
