A recent change request for the DefCore guidelines to “Flag validation tests as being OS specific[1]" has sparked a larger discussion about whether DefCore should explictly require running Linux as a compute capability. The DefCore Committee has prepared a document[2] covering the issue and possible actions, and is requesting review and comment from the community, Board[3], and Technical Committee. The DefCore committee would like to bring this topic for formal discussion to the next TC meeting on December 8 to get input from TC on this issue.
