You require a cluster to run molecular docking at scale.

Non-Scalable Cluster

You can just take a bunch of computers, new or used, and an ethernet switch and put them together to make a cluster. That's what we used to do. As the cluster scales, this approach becomes unwieldy and certainly labor intensive to maintain. If you plan to scale and you can afford it, we recommend starting with a scalable design, below.

Minimalist Scalable Cluster - One computer - $20K

You can begin a scalable cluster with as few as one computer, albeit a biggish one. We recommend using a hypervisor so you can run multiple virtual machines on a single computer. You can get away without a rack, just put the machine in a sound-proof room. We would buy:

  • a) 1 x 128 core / 256 GB / 16 TB disk @ $20K
  • b) a workstation, but you could even use a laptop

Plug it in to the network and the power supply. That's it. That's all you need to get started.

Starter Scalable Cluster - $40K

If you can afford it, starting with a few more computers will be easier to scale up. This cluster would be an excellent resource and a good foundation for managed growth for a new group getting started. We would buy:

  • a) 1 x 96 TB NAS server, $18K
  • b) 1 x 128 core / 512 GB @ $20K
  • c) switch, cables, economy workstation: $2K

You do not need a rack, but you need a sound-proof room with normal room air conditioning.

  • 2 x 15A circuits.

Small Scaleable Cluster - $92K

If you had around $100K to spend, we would buy:

  • a) 1 x 96 TB NAS server, $18K
  • b) 3 x 128 core / 512 GB @ $20K
  • c) barebones rack, switch, cables: $1K
  • d) 4 workstations @ $2K = $8K
  • e) spare parts (disks, switch) $4K
  • f) ssh portal machine / firewall $1K

Sound proof room, 1 T of cooling = 12,000 Btu/h = 3.516 KW

  • 30 A @ 208V (e.g. 1 x L6-30)

Bigger Scaleable Cluster - $250K

If you had around $250K to spend, we would buy:

  • a) 2 x 96 TB NAS server @ $18K = $36K
  • b) 10 x 128 core / 512 GB @ $20K = $200K
  • c) barebones rack, switch, cables: $1K
  • d) 4 workstations @ $2K = $8K
  • e) spare parts (disks, switch) $4K
  • f) ssh portal machine / firewall $1K

Sound proof room, 5 T of cooling

  • 90 A @ 208V (e.g. 3 L6-30s)
