The traditional programming models and open standards for communications between processing elements have been left behind somewhat. The interconnect topologies have become more complex and fragmented. No longer is there a clear, unified communication standard that is suitable for all the new interfaces introduced by these heterogeneous architectures. Abaco felt no existing open standard API provided a unified solution. Abaco presented their case the Khronos Group proposing a new standard API called Takyon. Khronos has listened and created the “Heterogeneous Communications” Exploratory Group with a goal to gather industry support for development of a new standard and solicit additional proposals. Take a look and contribute here. For a more in-depth description of the problem, be sure to read Abaco's blog "Behind the times".
