Update to Project Stage - 1

As I told in the last post (https://asharma206-spo600.blogspot.com/2020/04/project-stage-1.html), I did not have much luck figuring out how to set the optimization level for the build of my software. But with some help from the professor and reading some documentation about cmake, I finally managed to set the optimization level and decided to update my benchmarks.
I set the CXX_FLAGS to "-O1 -DNDEBUG" for all builds. and surprisingly the execution of the software which was taking about 6 mins and 44 secs, got reduced significantly to just 24%. So I increased the size of one of the files that the execution of the software was taking place on so it would take more than 4 mins.
All I did was appended the file multiple times to a new file using a loop:
{for (X=0; X<no. of times to append; X++) ; do cat file1.txt >> newfile.txt ; done}

Now before I did this, I set the level of optimization to -02 (recommended) and then I rebuild and decided to take the new benchmarks.

                                                                       Results

AArchie (AArch64)

Once again as in the last post, the values are in seconds and ranged from about 284.42 to 283.35, with a variation of about 0.37%.



Xerxes (x86_64)

The benchmarks for Xerxes ranged from about 244.36 to 243.84, with a variation of just about 0.21%.


Another small thing I would like to point out that I think is important here is, when I was working on setting optimizations and removing them and experimenting with them, a very key step is making sure the build files are deleted and then build again before you can run the updated version of the code. So that is make clean and then make. This is important when we want program to recompile with our updated options.
With that being said and my new benchmarks in, I'll be looking forward to do the profiling on this software and hopefully I can optimize it by some bit by the end of this course. I will keep you guys updated.
