Like drivers/multicomputer? > multicomputer" is an interesting name for these kind of devices but has several issues: a) The definition I found for multicomputer online was "A computer made up of several computers. The term generally refers to an architecture in which each processor has its own memory rather than multiple processors with a shared memory. A multicore computer, although it sounds similar, would not be a multicomputer because the multiple cores share a common memory." Intel MIC X100 devices typically have upto 244 CPUs (61 cores) on the card sharing common card memory so multicomputer would not be accurate based on this definition. b) X100 MIC devices have always been referred to Coprocessors and never as multicomputers in product specifications @ http://software.intel.com/en-us/mic-developer c) multicomputer is a very long path name. Given these issues, we would like to stick to drivers/misc/mic/ unless you have objections to this approach. Thanks for the feedback.
