Linux clusters outshined by supercomputers in HPC (Search Enterprise Linux)Linux clusters outshined by supercomputers in HPC (Search Enterprise Linux)Posted Aug 18, 2004 14:26 UTC (Wed) by snitm (guest, #4031)In reply to: Linux clusters outshined by supercomputers in HPC (Search Enterprise Linux) by joachim.W Parent article: Linux clusters outshined by supercomputers in HPC (Search Enterprise Linux)
You don't _need_ to differ between the two. Cray's XD1 uses COTS cpus, memory, and infiniband. The fact that they have their own custom IB to HT bridge, motherboard and chassis, while significant, does not not justify Cray's "purpose-built" marketing campaign. All high-end HPC Linux clusters are purpose-built. Cray has acquired a high-end Linux clustering architecture from OctigaBay. They should call it like it is and not spin the XD1 to be something its not.

I was not saying Cray has nothing to be marketing; I just think they shouldn't try to spin their XD1 as something other than Linux cluster technology. Yes the XD1 employs more advanced technologies and Cray is ahead of the curve BUT its the logical evolution of high-end Linux clustering. Cray has a window of opportunity being the first to market but they are floundering because the XD1 is so much more money than traditional high-end Linux clusters that use IB or Myrinet. So they are trying to sell the new cadilac of Linux clustering and at the same time distance themselves from the XD1's Linux clustering roots. Its comical.
