==Intel Adviser (Dmytro)==
'''What can the Advisor Do:'''
1. Vectorization Optimization
* Use the cache-aware Roofline Analysis to identify high-impact, under-optimized loops and get tips for faster code.
* Quickly find what's blocking vectorization where it matters most to make the best use of your machine's Single Instruction Multiple Data (SIMD) capabilities.
* Identify where it is safe to force compiler vectorization.
* Use memory analysis to find inefficient memory usage.
2. Thread Prototyping
* Use Threading Advisor to fast-track threading design.
* Its simple workflow lets you quickly model threading designs while delivering the data and tips you need to make faster design and optimization decisions.

Our Hotspot analysis from VTune(see previous section for details on VTune) identified that there are two bottlenecks in our code:
* imageToScalfile:///home/dmytro/Pictures/Screenshot%20from%202018-11-29%2017-42-19.png
eNaive - the main conversion function that creates image drawn with characters from the original buffer.
* calcLum - averages out the RGB values of a single pixel to convert it to grey scale.
See the details below:
