Comprehensive Learning Guide on CUDA's `__byte_perm` Function

Introduction

The __byte_perm function in CUDA is a powerful intrinsic designed for byte-level manipulation of 32-bit integers, commonly used in GPU-accelerated applications like cryptographic operations, data formatting, and Bitcoin script construction. It allows developers to select and rearrange bytes from two 32-bit inputs, x and y, into a new 32-bit output using a selector s. This guide provides a detailed explanation of how __byte_perm works, with a focus on constructing selector values, and includes practical examples to clarify its usage and address common pitfalls, particularly in the context of your Bitcoin P2SH script construction.

Function Signature

__device__ unsigned int __byte_perm(unsigned int x, unsigned int y, unsigned int s);

Parameters:

Summary of Evidence that P2P Solutions Foundation (P2PS) is a Scam Token (by Grok)

Key Points

Research suggests P2P Solutions Foundation (P2PS) is likely a scam token, with evidence including user reports of frozen accounts and failed transactions.
The contract owner has frozen numerous accounts, which could be a tactic to lock users out of their investments, a common scam behavior.
Community discussions on Reddit accuse P2PS of being a scam, but there are no official reports from regulatory bodies.
It seems likely that major platforms like CoinMarketCap, Etherscan, and MetaMask do not flag tokens as scams, relying on community awareness instead.
An unexpected detail is the high number of freeze transactions (22) by the owner, indicating systematic locking, which aligns with scam tactics but isn't officially confirmed.
