What is the role of "Link Time Optimization" in distributed computing -- C and C++ computing over OpenSHMEM with GPUs

[Azr_geek]

Hello @Azoth,

Link Time Optimization (LTO) helps make programs run faster and more efficient. In simple words, when you're working with C or C++ code that uses OpenSHMEM for distributed computing and GPUs, LTO looks at all the parts of your code after they've been written. It then finds ways to combine and optimize these parts before the program is built and run.

This can lead to better performance because:
1 It reduces unnecessary code or duplicates.
2 It improves how different parts of the program work together.
3 It can make better use of the GPU and network resources when running across multiple computers.

So, in distributed computing with GPUs, LTO helps your program run smoother and faster by fine-tuning everything just before it starts working.
