I have seen the GNAT for RT-Linux press release. Whenever it is released, it will be a very interesting product for different projects I�m affiliated with. However, it leaves me wondering about one thing. According to my (crude) definition of a homogenous distributed system, it basically allows data to be correctly interpreted from the native representation on any node in the distributed system. If data has to be transformed to a neutral format to be correctly interpreted after a transfer between nodes, the system is heterogeneous. A homogenous system allows programs to pass data as it is represented natively between programs without transformation, which has some obvious benefits and drawbacks. So, is a distributed system based on Linux and RT-Linux nodes running GNAT Ada programs a homogenous system? Obviously, there are many qualifications to be made. Please, if there is any light to be shed on the issue! Rgds, Daniel PS. Please mail me directly if you can, I don�t come around to reading the list more than once a month :-( PPS Why does my spell checker say �homogenous� is OK; as is �homogeneous�; �heterogenous� is not OK, it only allows �heterogeneous�? ;-)
