I would love to hear more about this hardware. Can you elaborate?

  You can buy that sort of kit off-the-shelf now, from HP and others. It's nothing exotic, it's basically your desktop PC on steroids. NUMA is 90's tech from Sequent.

    Can the CPU(s) address 512GB of RAM? If so, what operating system/OS configuration can handle that?
    • cube13 15y ago
      RHEL6 has a theoretical maximum of 48 bit addressing space(at least with the 1st beta), which is 256 TB. From: http://www.theregister.co.uk/2010/04/21/redhat_rhel6_beta_1/ http://www.theregister.co.uk/2010/04/21/redhat_rhel6_beta_1/

      x86-64 architecture presently allows 256 TB (48-bits) physical addressing, and Itanium and at least some its operating systems (HP-UX, OpenVMS) have 50-bit physical addressing available. The big HP NUMA boxes are Superdome and Superdome 2, and those have global memory access, though access to the local memory is faster than the remote memory; the requisite non-uniform memory access speeds. Last I checked, the current Superdome and Superdome 2 series maxed out around two and four terabytes of physical memory. If the current four terabyte maximum memory configurations and possibly the architectural 50-bit addressing aren't enough and you're willing and able to buy that much physical memory, then HP would probably interested in chatting with you. No RHEL on Itanium, though.

        For some reason, I thought that Intel had abandoned the Itanium platform. I was surprised to see that HP was still marketing machines based on that processor line.

          You might be thinking of Microsoft, which dropped support for Itanium in 2010.

            Or Oracle who dropped support in 2011 (and were sued by HP): http://www.zdnet.com/blog/btl/hp-sues-oracle-over-itanium-support-does-the-lawsuit-make-sense/50822 http://www.zdnet.com/blog/btl/hp-sues-oracle-over-itanium-su...

              Or glibc, which dropped support a few weeks ago: http://repo.or.cz/w/glibc.git/commit/d75a0a62b12c35ee85f786d5f8d155ab39909411 http://repo.or.cz/w/glibc.git/commit/d75a0a62b12c35ee85f786d...

      z/OS :)

        Sort of. As of right now executable code is only allowed in the lower 2GB, but data is allowed anywhere. "Below the bar" I think is the term.
