Steinar H. Gunderson f0793a2080 Merge commit '9032c6cbe74ccf7e8963755501e7e6cc473ae471' into cluster 
This is a rather involved merge, since the cluster changes interact
fairly badly with the refactoring we're merging:

The new code wants the search to know nothing at all about the UCI protocol,
it just calls a callback with some worker information (including a Position),
which then transforms that information into a InfoFull which is then sent
through another callback, upon which UCIEngine converts it to UCI and writes
it to stdout.

On the other hand, the MPI information wants to exchange PVs between workers
at this point, and it wants to use the UCI string as the primary medium of
exchange. Position is a lot of work to serialize, so we choose a middle road;
we capture the InfoFull by switching out the callback, serializes it, does the
MPI exchange on that, unserializes it and then continues with the print callback
(if there is new information).

clang-format-18 is available in ubuntu noble(24.04), if you are on
a version lower than that you can use the update script from llvm.

Windows users should be able to download and use clang-format from
their release builds https://github.com/llvm/llvm-project/releases
or get the latest from msys2
https://packages.msys2.org/package/mingw-w64-x86_64-clang.

macOS users can resort to "brew install clang-format".

Recently when I overhauled these comments, Disservin asked why these

-5. Now we don't, so fix these to the obvious place.

Disservin 00a28ae325 Add helpers for managing aligned memory 
Previously, we had two type aliases, LargePagePtr and AlignedPtr, which
required manually initializing the aligned memory for the pointer.

The new helpers:

- make_unique_aligned
- make_unique_large_page

are now available for allocating aligned memory (with large pages). They
behave similarly to std::make_unique, ensuring objects allocated with
these functions follow RAII.

The old approach had issues with initializing non-trivial types or
arrays of objects. The evaluation function of the network is now a
unique pointer to an array instead of an array of unique pointers.

Memory related functions have been moved into memory.h

Michael ChalyandJoost VandeVondele 783dfc2eb2 Adjust return bonus from tt cutoffs at fail highs 
This is reintroduction of the recently simplified logic - if positive tt cutoff
occurs return not a tt value but smth between it and beta.  Difference is that
instead of static linear combination there we use basically the same formula as
we do in the main search - with the only difference being using tt depth
instead of depth, which makes a lot of sense.

Linmiao XuandJoost VandeVondele cb4a623119 Update default smallnet to nn-37f18f62d772.nnue 
Created by training L1-128 from scratch with:
- skipping based on simple eval in the trainer, for compatibility with
  regular binpacks without requiring pre-filtering all binpacks
- minimum simple eval of 950, lower than 1000 previously
- usage of some hse-v1 binpacks with minimum simple eval 1000
- addition of hse-v6 binpacks with minimum simple eval 500
- permuting the FT with 10k positions from fishpack32.binpack
- torch.compile to speed up smallnet training

Training is significantly slower when using non-pre-filtered binpacks due to
the increased skipping required.

This net was reached at epoch 339.

rn5f107s2andJoost VandeVondele b34a690cd4 MCP more after a bad singular search 
The idea is, that if we have the information that the singular search failed low and therefore produced an upperbound score, we can use the score from singularsearch as approximate upperbound as to what bestValue our non ttMoves will produce. If this value is well below alpha, we assume that all non-ttMoves will score below alpha and therfore can skip more moves.
This patch also sets up variables for future patches wanting to use teh singular search result outside of singular extensions, in singularBound and singularValue, meaning further patches using this search result to affect various pruning techniques can be tried.
