Pitching plan: https://github.com/jfalcou/eve/wiki/conference-2021

What's left?

• Elevator pitch: we show comparisons between std::find_if, std::remove_if and eve::find_if, eve::remove_if on my machine.
  DONE

• Why are we better? SIMD. Crash course into SIMD architectures: from sse2 - to avx512, arm neon. Some measurements between architectures.
  Needed inclusive scan ported: [FEATURE] eve::inclusive_scan(wide x, plus, zero) #894
  I dunno how compress_store will do on sse2 - probably extremly bad.
  Which is maybe fare or we should try things.

• What's eve? 3 layers: core, math, algo.
  No code needed.

• What basic algos we have at the time? (I feel we need at least all algos I had last year: find_if, transform_reduce/reduce, inclusive_scan).
  find_if
  mismatch
  reduce
  hack transform reduce/skip transform reduce/ do it proper?
  inclusive scan algorithm?

• How they are implemented under the hood? Show case strlen
  Done

• How to collect indexes
  Mostly done

• ZIP: running algorithms on parallel arrays
  Just show that mismatch is implemented with find_if I think.

• Objects: our object structure, soa_vector, convert between objects on cartesian coordinate planes to polar (or maybe something better - just a pretty real example).

• Algorithm support for product types.
  References for products?
  soa_vector basic: push_back, erase (needs eve::algo::copy?), scalar iterator
  At this point remove won't with product types. Needs: [FEATURE] compress store for zip #868

• More about customisation points: remove spaces using a manually implemented crazy x86 trick.
  Not done but simple

• (Stretch goal): Build stuff. How one can build a library in C++20 with eve for different architectures and integrate it with the C++11 code.
  Not gonna happen

Are we going to shoot everything at once to the 1st conference or can we spread that over C++Con, MC++, C++Russia and CPPPP ?

I think one talk given multiple times.
objects will blow the mind and we need to get there.
