batch image processing (JPEG resize & crop) / GPU based

We need professional help to create a real time DZI (Deep Zoom Image) processing script. The script shoud be GPU based for high perfomance and capable of multiprocessing. Input file format: Single JPEG file, approx. 10-50MB size Output file format: DZI (Deep Zoom Image) Input and output files should be stored as keys at a remote redis server (10 Gbit connection). To reduce disk load and time, the images should NOT be stored on disk. We are planning to run the script on a Amazon AWS GPU based instance (g2.2xlarge). The underlaying OS should preferably be Debian 7. What we will do: - OS setup, including necessary Nvidia drivers - Redis Server setup Your job: - developing a script (C, PHP, Perl, Python...) that reads the input image from the redis servers - creates all needed output images tiles as per DZI specification - store each image tile to the redis server Performance: - the script should be high perfomance and capable of using multi GPU threading. - preferable way could for example be: 1) JPEG decompressing, store to RAM 2) Resize for each level 3) Crop to generate the tiles 4) store tiles to redis and free RAM Speed: - Image processing should take no longer than 500ms per job even if there are 10 different jobs running simultaneously.
