| − | Damascus is the working name for the Earlham Computer Science Department's upcoming cluster computer.
| |
| | | | |
| − | At the moment Damascus 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?
| |
| − | *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 works
| |
| − | *What software stack do we want to run? Vendor supplied or the BCCD?
| |
| − | **Both. Vendor-supplied base with a BCCD virtual machine
| |
| − | * Do compute nodes have spinning disk?
| |
| − | ** Compute nodes have a spinning disk
| |
| − | * What's on the local persistent store? /tmp? An entire OS?
| |

| |
| − | == 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.
