I am looking for a high performance data structure on GPU (preferably over CUDA). The CUDPP is something cool but it does not satisfy my requirements because I want my key to be fixed size int array. I need to query 10k+ queries per second over a KEY-VALUE store of size 1M+. Is there any library already providing such type of functionality. I tried alternates on CPU but they are not that good for the purpose.
I haven't used it, though I have heard about a hashmap extension for CUDA Thrust. Present here:
Cuda-thrust-extensions library

so i had a homework to get a document (a buffer of ASCII bytes) which has the CRC32 hash (the gzip variant of CRC32), of 0xbbd1264f and unti now i don't know how to get it so if someone know how to do that please answer
spoof will calculate what bits out of a provided candidate set to invert in order to force the CRC to the desired value.
From your question, I think you mean generating collision for crc32 with your document.
You can find a lot of articles about creating crc32 collisions. For example you can see it here, here or here.

Is there any probabilistic algorithm for calculating set cardinality taking into account that must support deleting elements from set? I've been using HyperLogLogs for calculating cardinalities of some sets and their unions but when necessity of deleting elements from set emerged my current solution became unappropriate. Maybe there are some researches or papers related to this topic you could advise.

I'm having a really hard time visualizing how the Bellman-Ford algorithm works purely through reading code. Does anyone know of an visual example (video, slideshow) that works through an actual graph with that algorithm? Thanks!
I think that this page might be what you are looking for. It does indeed run through the algorithm on a graph, and you may use the UI below to pause the visualization, or run through individual frames one at a time so that you can visualize it at your own pace.

a few weeks ago I saw a website with a powerful generator to create beautiful pictures of own source code files. The generator created images with variable effects like perspective transformations and depth of field, etc.
Typically I don't ask such questions in here but I googled more than 2hrs and I cannot find this generator anymore. I'm really going crazy - I know this site exists ...
Here's a sample picture of code made with this generator:
Thank you very much!

I'm looking for an algorithm that can tell me where are the eye(s) looking at on a photo/webcam realtime feed.
I've already searched a lot but I don't want to start with a lot of complexity right now.
It's just for fun. My idea it's to have some method that receives an image and returns a coordinate with the place that the user is looking (on the computer screen).
