Libfairydust is a small wrapper library intended for use with GPU clusters that 'hijacks' CUDA and OpenCL calls. It can be used to 're-route' calls to a certain GPU, so a process requesting GPU#0 might end up running on GPU#4 without knowing (or caring) about it. This works completely transparently and does not need any sort of 'cooperation' from the application, changes to code, or relinking.
Zebra_cURL is a high performance PHP library acting as a wrapper to PHP's libcurl library, which not only allows the running of multiple requests at once asynchronously in parallel, but as soon as one thread finishes, it can be processed right away without having to wait for the other threads in the queue to finish, eliminating wasted CPU cycles from busy waiting. This result is a faster and more efficient way of processing large quantities of cURL requests (like fetching thousands of RSS feeds at once), drastically reducing processing time. This script supports GET (with caching) and POST requests, and basic downloads as well as downloads from FTP servers, HTTP Authentication, and requests through proxy servers. For maximum efficiency, downloads are streamed (bytes downloaded are directly written to disk), removing the unnecessary strain from the server of having to read files into memory first and then writing them to disk.
APIcaller is a class that helps you to build API wrappers. You don't have to worry about building URLs, or even about parsing the requested data. As an example, if an API requires an API key, you can set this key as a default value and it'll be always sent with the API request. The API needs to return the data in JSON format, otherwise an execption will be thrown.
