It is essentially libjpeg with SIMD instructions and some functionality to make it a little faster. \r\n\r\nJake and I compiled and built it for DoC machines (as we don't have sudo rights), so I can either make a script for that or I think the command should be `sudo apt-get install libjpeg-turbo8` instead of `sudo apt-get install libjpeg8`. Let me double check that on an AWS instance (Jake and I are being careful about what we start up now...) and I'll let you know if we need anything different if the above is allowed.\r\n\r\nOne caveat is that I think you need to uninstall libjpeg, but it does provide all of the functionality of libjpeg, but with the speed ups - so possibly a bonus for everyone in the course? If you don't want to swap out libjpeg for libjpeg-turbo, we can just include the shared object files needed and ensure that it compiles and runs with out affecting the normal libjpeg (have to change the LD_LIBRARY_PATH for dynamic linking at one point but only for our session and can be done in the makefile).
