Experiment with IPO/LTO

ax3l
ax3l commented Nov 12, 2019

Hi,

one could and should experiment with Interprocedural optimization (IPO) also known as link-time optimization (LTO), especially on the host side for smaller binaries and potentially faster code. It's supported by GCC, Clang, and ICC, among others, which are our typical go-to compilers in HPC.

It's very easy to implement as well

Particle Histogram 2D

1

ax3l commented Feb 18, 2022

Need for a reduced diagnostics addition: general 2D particle histogram (think: "np.histogram2d").

  • Applications: phase space, energy-emittance plots, etc.
    • Would be useful for WarpX, ImpactX, and HiPACE++
  • Size: fit into local GPU memory, e.g., default 1024^2
  • 3 parser functions: axis1, axis2, filter
    • All three into the kernel
    • No RNG needed
  • Can be loosely on the exiting red

Simple, self-contained, clean code, well-documented, hobbyist 64-bit operating system for Intel and AMD processors. It's written in Assembly (Intel syntax) and C (GNU99 Standard) in which I strive for adding comments to the source code so it could be used as a reference for future OS developers
