Cluster Theory
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
Starter Scalable Cluster - $40K
If you can afford it, starting with a few more computers will be easier to scale up.
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)
