We now have an Intel Xeon Phi Applications and Solutions catalog at https://software.intel.com/en-us/articles/intel-xeon-phi-coprocessor-applications-and-solutions-catalog -- this is also accessible from the home page at https://software.intel.com/en-us/mic-developer
The plan is to continue to keep this document current and updated -- and at some point in the near future it will be provided in html navigation form.
if you find that your optimized or ported application is not on this catalog, please let us know! In the meantime, we hope you will find this document useful
