FlashAttention
Fast and memory-efficient exact attention
FlashAttention is a high-performance deep learning optimization library that reimplements the attention mechanism used in transformer models to be significantly faster and more memory-efficient than standard implementations. It achieves this by using IO-aware algorithms that minimize memory reads and writes, reducing the quadratic memory overhead typically associated with attention operations. The project provides implementations of FlashAttention, FlashAttention-2, and newer iterations optimized for modern GPU architectures such as NVIDIA Hopper and AMD accelerators. By improving both forward and backward pass efficiency, it enables training and inference of large language models with longer sequence lengths and higher throughput. ... -

DiffOpt.jl
Differentiating convex optimization programs w.r.t. program parameters
...Note that this package does not contain any solver. This package has two major backends, available via the reverse_differentiate! and forward_differentiate! methods, to differentiate models (quadratic or conic) with optimal solutions. Differentiable optimization is a promising field of convex optimization and has many potential applications in game theory, control theory and machine learning. Recent work has shown how to differentiate specific subclasses of convex optimization problems. But several applications remain unexplored. ... -

QFT fork-yzhs
testbed for QFT and such
This is a fork of Colin Benner's Frobenius benchmarking. https://github.com/yzhs/frobenius-test Quadratic Frobenius primality Test (QFT) as devised by Grantham has two relatively expensive first steps. In other projects, techniques were examined that may reduce that expense and are tested here. -

hash_val_4_Bloom
search for hash values used in Bloom filter for QNR membership
FenderBender -- on MersenneForum.org "Determine Squares" -- came up with using Bloom filter to detect Quadratic non-residues modulo small primes in order to reject what inputs are certainly not square roots. This reduces, by > 99%, the amount of actual square root calc's done and therefore is more efficient and faster. Search fur 32-bit vs 64-bit, hash values that make "perfect" Bloom filter. Variety of (simple) hash functions, requiring 2, 3, 4 or 5 hash values. -

No-factor-base (NFB) sub-exponential factorization algorithm
This is an easy-to-understand algorithm of integer factorization with heuristically evaluated complexity L(4/15, 2), which is better than the general number field sieve algorithm with L(1/3, 1.923). NFB searches common factors of the quadratic residues modulo n using GCD. All relations are processed by the Gaussian elimination procedure. Different strategies of searching the relations can be applied, many giving complexity better than L(1/3, 1.923). -

Sparse Attention
"Generating Long Sequences with Sparse Transformers" examples
Sparse Attention is OpenAI’s code release for the Sparse Transformer model, introduced in the paper Generating Long Sequences with Sparse Transformers. It explores how modifying the self-attention mechanism with sparse patterns can reduce the quadratic scaling of standard transformers, making it possible to model much longer sequences efficiently. The repository provides implementations of sparse attention layers, training code, and evaluation scripts for benchmark datasets. It highlights both fixed and learnable sparsity patterns that trade off computational cost and model expressiveness. ... -

...Each one solves trinomials, but each one solves them a little differently. If you want all of them, just download "TRINOM". Look below for details. ANSWER: Simply gives the x-values from the quadratic formula. FACTOR: Like the name implies, this gives the answers in factored form. This code has been improved for simplicity. QUADFRM: This program displays the "work" from the quadratic formula. This includes simplifying the radical!!! (you're welcome). Be warned, this is the only program that struggles with bigger numbers.
