Question

The hacker group Desdeia tries to break our old weak cipher which we used for the communication with the Duchess of Ligovia. It's
generally known that an actual breaking of the cipher needs the reviewing a huge amount of variants which probably lasts a couple of
months. Additionally we know that the reviewing of different variants needs always the same server resource.
Using our intelligence sources we tried to get some information about the actual progress of breaking, but we got only some fragments:
• The hacker group Desdeia uses for breaking their powerful four-core server which resources are fully dedicated to breaking process.
. The actual breaking process began exactly at noon, but we don't know, on which day.
. By the noon of 2nd of April, already 648,467,673 variants were successfully reviewed.
Exactly at this noon, when the breaking process was already lasted for 19 days, it was attempted to double the server speed. The
doubling itself was failed, but instead of it there was actually succeeded to increase the server speed by 73.40%. Additionally we know
that 14.397% of total variants are already reviewed until this moment.
.
. At noon of 19th of May, when already 55.13% of total variants were reviewed, one server core (from a total of four) went suddenly out of
order. Consequently, the further breaking process (since the noon of May 19th) was continued only with three cores which caused the
actual speed lowering (new speed is 75% in comparison with the previous).
Task:
Find the exact date and time when Desdeia server will finish the breaking process (assuming that there will be no more server speed
changes beside the above-mentioned two occasions). Describe your solution process.

Using MPI, develop a project to decode a password using brute force, the passwordlength is a variable entered by the user. The password will be randomly generated as a combinationof lower and upper case characters, digits, and special characters. Your project will distribute thework between the cores to figure out what was the password using brute force checking. You candivide the work between the cores in two ways; first assign for each core a part from the password,second each core will be responsible to check the entire password within a range of characters,digits, and special characters, such that each core will check a different range. You need tomeasure and compare the time needed to break the password using parallel computing and serialcomputing for different password lengths.
