Al-Salam is the working name for the Earlham Computer Science Department's upcoming cluster computer.
At the moment Al-Salam exists only as a $40,000 grant and a growing list of tentative specifications:

Latest Overarching Questions
- Should we build this machine ourselves?
- Are we wasting our money and learning opportunity letting them do the building for us?
- 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?
- 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?
- Both. Vendor-supplied base with a BCCD virtual machine
- 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
- Nodes - case, motherboard(s), power supply, CPU, RAM, GPGPU cards
- Switch - managed, cut-through
- Fitz: Having a hard time finding anyone who sells cut-through switches
- How about this store-and-forward switch from hp?
- Fitz: Having a hard time finding anyone who sells cut-through switches
- 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.
