Metal implementation of subgroupPartitionNV
// Created by Timothy Davison on 2023-06-21.
//
// This is a Metal implementation of subgroupPartitionNV. You use it to find a mask of
// the other threads in a simd-group with the same value (a partition of the simd-group about
// a set of values).
//
// Feel free to use this in your code. Please share any fixes or ideas to make it faster.

Last active March 2, 2016 18:21 — forked from unbracketed/export_repo_issues_to_csv.py
Export Issues from Github repo to CSV (API v3)
#!/usr/bin/env python
"""
Exports Issues from a specified repository to a CSV and/or JSON file
Uses basic authentication (Github username + password) to retrieve Issues
from a repository that username has access to. If a public repository,
no user/password needs to be provided. Supports Github API v3.
Orginally based on a script by Brian Luft at https://gist.github.com/unbracketed/3380407
This requires installing the 'requests' package (https://pypi.python.org/pypi/requests/).

useful min/max/abs/sign identities
max(-x,-y) = -min(x,y)
min(-x,-y) = -max(x,y)
abs(x) = abs(-x)
abs(x) = max(x,-x) = -min(x,-x)
abs(x*a) = if (a >= 0) abs(x)*a
(a < 0) -abs(x)*a
// basically any commutative operation
min(x,y) + max(x,y) = x + y
