• Brief history
  • 2006 swallowtail (Dell PE1955, Infiniband, imw, emw)
  • 2010 greentail (HP gen6 blade servers, hp12)
  • 2013 sharptail (Microway storage, K20s, Infiniband, mw256/mwgpu)
  • 2014 mw256fd (Dell 2006 replacement with Supermicro nodes)
  • 2015 tinymem (Supermicro bare metal, expansion for serial jobs)
  • 2017 mw128 (first new faculty startup funds)
  • 2018 6/25 Today's meeting

• Since 2006
  • Grown from 256 to roughly 1,200 physical CPU cores
  • Processed 3,165,752 jobs (by 18jun2018)
  • Compute capacity over 60 teraflops (DPFP; 38 cpu side, 25 gpu side)
  • Total memory footprint is near 7.5 TB
  • About 500 accounts have been created (incl 22 collaborator and 100 class accounts)

• Funding / charge scheme: is it working for you?
  • Last 2 years, $15K target realized each year.

• Status of our cluster development fund
  • $140K come July 1st, 2018
  • Time for some new hardware? Retirement of hp12 nodes?

• 2017 Benchmarks of some new hardware
  • Donation led to purchase of four GTX1080ti commercial grade GPU server
  • Amber 16. Nucleosome bench runs 4.5x faster than on a K20
  • Gromacs 5.1.4. Colin's multidir bench runs about 2x faster than on a K20
  • Lammps 11Aug17. Colloid example runs about 11x faster than a K20
  • FSL 5.0.10. BFT bedpostx tests run 16x faster on CPU, a whopping 118x faster on GPU vs CPU.
  • Price of 128gb node in 2017 was $8,250…price of 256gb node in 2018 $10,500

• 2017 IBM bought Platform Inc (developers of LSF, Openlava is LSF4.2 open source branch)
  • Promptly accused Openlava of copyright infringement in v3.x (US DMCA law, no proof needed).
  • Fall back option to v2.2 (definitely free of infringement, minor disruption)
  • Move forward option, adopt SLURM (LBL developers, major disruption)

• New HPC Advisory Group Member

• Tidbits
  • Bought deep U42 rack with AC cooling onboard and two PDUs
  • Pushed Angstrom rack (bss24) out of our area, ready to recycle that
  • Currently we have two U42 racks empty with power
  • Cooling needs to be provided with any new major purchases (provost, ITS, HPC?)
  • 60 TB raw storage purchased for sharptail (/home2 for users with specific needs)
  • Everything is out of warranty but
    • cottontail (03/2019),
    • ringtail & n78 (10/2020)
    • mw128_nodes (06/2020)
  • All Infiniband ports are in use
