deln 0.1.1

GPU-accelerated kernels for exotic / scientific math operators.

deln

GPU-accelerated kernels for exotic / scientific math — 174 operators across 34 domains (special functions, information theory, point processes, copulas, Bayesian & GP methods, PDE solvers, computational geometry, materials, medical imaging, and more), exposed as plain functions you call on torch tensors.

pip install deln

Quick start

import torch
import deln

deln.init("[e-mail]")          # REQUIRED once, before any algorithm

from deln.specfun import bessel_i0
x = torch.linspace(0.0, 3.0, 1024, device="cuda")
y = bessel_i0(x)                       # runs on the GPU, returns on x's device

If you call any algorithm before deln.init(...), it raises deln.DelnNotInitializedError telling you to initialize first.

How it works

• Every algorithm is a function grouped under its domain submodule: deln.specfun.bessel_i0, deln.quant-style domains, deln.pointproc.hawkes_log_likelihood, deln.medimg.radon_backprojection, …
• Pass torch tensors (CUDA or CPU); the result comes back on the same device as the inputs — no host round-trips.
• Each function is documented (help(bessel_i0)), with its parameters and the initialization requirement.

Discovering algorithms

import deln
deln.init("[e-mail]")
deln.list_algorithms()                 # -> every available operator name
help(deln.specfun.bessel_i0)           # -> docstring, params, notes
