#4945 — More about Energy efficiency..

Hello,


More about Energy efficiency..

You have to be aware that parallelization of the software
can lower power consumption, and here is the formula
that permits you to calculate the power consumption of
"parallel" software programs:

Power consumption of the total cores =  (The number of cores) * ( 
1/(Parallel speedup))^3) * (Power consumption of the single core).


Also read the following about energy efficiency:

Energy efficiency isn’t just a hardware problem. Your programming
language choices can have serious effects on the efficiency of your
energy consumption. We dive deep into what makes a programming language
energy efficient.

As the researchers discovered, the CPU-based energy consumption always
represents the majority of the energy consumed.

What Pereira et. al. found wasn’t entirely surprising: speed does not
always equate energy efficiency. Compiled languages like C, C++, Rust,
and Ada ranked as some of the most energy efficient languages out there,
and Java and FreePascal are also good at Energy efficiency.

RAM is still expensive and slow, relative to CPUs

And "memory" usage efficiency is important for mobile devices.

So Delphi and FreePascal compilers are also still "useful" for mobile
devices, because Delphi and FreePascal are good if you are considering
time and memory or energy and memory, and the following pascal benchmark
was done with FreePascal, and the benchmark shows that C, Go and Pascal
do rather better if you’re considering languages based on time and
memory or energy and memory.
