But none of the ones you list are more than vaguely related to HPC. Personally I'd love it if clocks in clusters were better than they often are now but that's because a surprising number of people seem to think they can live without ntp and are content with living with large discrepancies across the cluster. The only thing I've found ntp to be lacking in is the ability to compile complex software over NFS on 2.6 kernels which have 64 bit timestamps, mpich springs to mind as the configure step often enters an infinite loop. This isn't helped by some of the cheaper NAS offerings not supporting ntp at all. In short, I'd use it if it was packaged with the distro and just worked out the box (without using multicast preferably) but it's absence isn't enough to cause me problems.
