Cray

Dave's Cray has now retired to hopefully find a home in one of a few computer science museums. Archived for other hackerspaces planning supercomputing workshops (this is basically how far we got).

Projects

Possible workshops, tutorials and training might include:

MPI / Parallel programming

RDMA and OS bypass techniques

LAPack, tuning

Various HPC libraries (MAGMA, etc.)

Eclipse Parallel Tools Platform (Would be cool to have a profile for our cluster to integrate connecting and job submission)

Architecture

Kernel / Driver development

Firmware

System / Cluster administration

Job schedulers (Moab and SLURM)

Profiling / Debugging distributed applications

Virtualization (OpenStack?, Proxmox?)

Configuration management

Data Management (GridFTP, Globus, etc.)

Specifications

Resources

20 Compute nodes (up to 28 if more memory purchased)

8 GB per compute node

Total cores: 80 cores

Interconnect: Cray SeaStar ASIC (24 Gbps, full duplex)

Storage: Minimal initially, whatever we can find for the SMW

Rack Measures ~24" x ~55"

Cooling:In rack air cooled. (No phase change Ecoflex piping to worry about, etc.)

Noise: Operation Db: (?)

Power 208 3 phase Also see Available_Utilities

Estimations of load:

Dave: 8 to 10 kW at full load, and I'm hoping that's closer to 5 kW in reality"
