Al-Salam is the name for the Earlham Computer Science Department's venerable 13-node computing cluster.

Software

Al-salam was upgraded to CentOS 7 in summer 2019. The notes below, in "Archive", contain useful information, but the specifics may not be current to the cluster as it exists now.

Hardware notes

  • As{0,9,10} have a 500GB hard drive on it in addition to the 80GB, remember for configuration
  • As10: 500 drive appears when you run the installer but not in df -h; 80 drive has the OS but can’t seen the 500
  • As12 has 2 1TB hard drives in software RAID in addition to the 80GB

Archive

A few extra notes beyond these are available here so check first before moving forward with big changes.

Installation Notes

headnode

I'll be maintaining a script, /root/install/al-salam.sh, that will also serve as a log. Also following along with BobSCEd-new logs for consistency between clusters.

compute nodes

  • clone from bs1-new using udpcast
  • modify network, etc. settings from bobsced to al-salam

Latest Overarching Questions

  • Should we build this machine ourselves?
    1. Are we wasting our money and learning opportunity letting them do the building for us?
    2. If it is cheaper, Would it be a useful experience for the students this coming semester to take a large collection of hardware and make it into a cluster?
    3. Yes, this was pretty clear from the email thread in early December.
  • How much if any GPGPU hardware do we want? 0, 1 or 2 nodes worth?
  • Do we want a high bandwidth/low latency network?
    • We do not. More expensive than it is worth.
  • What software stack do we want to run? Vendor supplied or the BCCD?
    • Both. Vendor-supplied base with a BCCD virtual machine
      • Will the virtual machine support CUDA?
  • Do compute nodes have spinning disk?
    • Compute nodes have a spinning disk. Solid state is still expensive
  • What's on the local persistent store? /tmp? An entire OS?
  • Support
    • Consider getting the cheapest hardware support, loosing a node isn't critical as long as they send a replacement quickly.

Parts List

  1. Nodes - case, motherboard(s), power supply, CPU, RAM, GPGPU cards
  2. Switch - managed, cut-through
    1. Fitz: Having a hard time finding anyone who sells cut-through switches
      1. How about this store-and-forward switch from hp?
  3. Power distribution - rack-mount PDUs

Tentative Specifications

Budget

  • $35,000 (leaving $5,000 for discretionary spending)

Nodes

  • Intel Nehalem processors
  • 4 core processors minimum
    • Six cores still expensive
  • 1.5GB RAM per core

Specialty Nodes

  • Two nodes should support CUDA GPGPU

Educationally, we could expect to get significant use out of GPGPUs, but the production use is limited. Increasing the variance of the architecture landscape would be a bonus to education.

Network

  • Gigabit Ethernet fabric with switch

Disk

  • Spinning Disk

OS

  • Virtual BCCD on top of built-in OS.
