## Why people recommend it

- Practical drop-in CUDA replacement (4 comments in the sample): "ZLUDA is the “right” drop in CUDA replacement for almost any practical use case" ([source](https://news.ycombinator.com/item?id=47056172)) "if you want a practical path towards drop-in replacing CUDA, you want ZLUDA" ([source](https://news.ycombinator.com/item?id=47054903)) "this is closest thing we have to "cuda on non-nvidia" hardware" ([source](https://news.ycombinator.com/item?id=48904546))
- Open source, works with binaries (2 comments in the sample): "zluda is open source with extra features like game physics" ([source](https://news.ycombinator.com/item?id=49059075)) "which is open source and works on pre-compiled binaries" ([source](https://news.ycombinator.com/item?id=48904130))

## What people warn about

- Incomplete CUDA API coverage (2 comments in the sample): "ZLUDA doesn't have full coverage though and that means only a subset of cuda codebases can be ported successfully" ([source](https://news.ycombinator.com/item?id=47062125)) "ZLUDA basically crash on high memory demand, and only accounted for ~70% of CUDA API coverage" ([source](https://news.ycombinator.com/item?id=49034674))
- Earlier attempts failed (2 comments in the sample): "most previous attempts (like ZLUDA) hit a wall" ([source](https://news.ycombinator.com/item?id=47079382)) "Everyone who tried to compete failed hard" ([source](https://news.ycombinator.com/item?id=45824333))

## The badge

A product earns the Hacker Approved badge when at least 10 people recommend it, recommenders outnumber critics at least 2 to 1 (mixed feelings count toward neither side), it was recommended in at least 4 of the 12 months and in at least 5 different threads, and no single thread supplies more than half of the people who recommend it. Health and money products are never badged.
