Microsoft delays Windows for computers clusters

Microsoft announced that it has postponed the launch of a new version of Windows for computer clusters. First betas are expected in the second half of this year and the final version is planned for the first half of 2006. Microsoft also pointed out that this version of Windows is not aimed at the supercomputers like you find in the top 500 list that gets released annually. They said it is aimed at clusters that a department or even a single researcher might put together.
