Pricing example for 24 cores
Questions
Value/ utility of (Intel) hyperthreading?
Summary
You want 24 cores. Here are some options, and prices as of Jan 2014.

Notes

Typical compute cluster nodes
2 computers in one 1U rack-mount box.
24 cores, 128GB RAM, 4TB storage.
(12 cores, 64GB RAM, 2TB storage per computer )
|
$5.4K
|
Getting 24 cores on procs spread over 2 computers represents good value.
|
Intel Xeon E5 2620
(V2 coming soon)
|
4 procs, 2 on each of 2 motherboards.
|
Typical compute cluster nodes
2 computers in one 1U rack-mount box.
32 cores, 128GB RAM, 4TB storage.
(16 cores, 64GB RAM, 2TB storage per computer ). |
$7.3 |
Getting 32 cores on procs spread over 2 computers (instead of 24 cores, above). Pay extra for these extra cores:
$960 to get 2 more cores on each chip
|
Intel Xeon E5 2640
(V2 coming soon)
|
Again, 4 procs, 2 on each of 2 motherboards. Those procs are twice the price.
8-core proc price is $890ea, or a full $480ea more than 6-core proc. |
Single computer, rack-mount.
24 cores, 128GB RAM, 4TB storage.
|
$8.5K
|
To get similar power as $5.4K sytem (24 cores), but merged into a single system. Pay extra:
$1,920 for 4-capable chips upgrade
$1,180 for 4-capable motherboard upgrade
|
Intel Xeon E5 4607 V2 |
4 procs, but on one single motherboard. Those procs are twice the price.
4-proc capable proc price is $890ea, or a full $480ea more than 2-proc capable proc. |
Singe computer, desktop (but noisy and hot!)
24 cores, 128GB RAM, 4TB storage.
|
$9.5K
|
In addition to above $8.5K upgrade, pay extra:
~$1K for chassis upgrade (still noisy and hot, though)
|
Intel Xeon E5 4607 V2 |
Again, 4 procs, but on one single motherboard. Those procs are twice the price.
8-core proc (4-core capable) price is $890ea, or a full $480ea more than 6-core proc (4-core capable). |
Details
For each option:
- Each proc (processor) is 6 cores. 4 total procs
- More cores/ proc are available, but much more expensive. (Ex. An 8 core proc is twice the price.)
- Each option has a total of 128GB RAM. And 4TB of HD storage over 2 hard drives.
Spec's selected to allow an apples-to-apples price comparison, not because of a "sweet spot" for each scenario, and not necessarily "fitted" to your research needs.
- You may need to adjust the final specs, once you select a top-level option.
Does not include
Anything other than "the box".
- May also need UPS ($170), network cabling and switch ($100 or less)- not much else.
Base data
- $410 for each 6 cores chip, 2-capable (Intel Xeon E5 2620; V2 coming soon)
- $890 for each 8 cores chip, 2-capable (Intel Xeon E5 2640; V2 coming soon)
- $890 for each 6 cores chip, 4-capable (Intel Xeon E5 4607 V2)
- $1,600 for each 8 cores chip, 4-capable (Intel Xeon E5 4620 V2)
Dropping from 64GB per node to 32GB per node drops about $250 per node ($500 for a 2-node system). (And 16GB instead of 32GB is saving very little money, of course.)
- Question: Brian's quotes from Dell imply that our 64GB RAM (vs. $32GB) costs $1,000, not $500. How to account for the extra $500 ($1,000-500) in ChemIT's quote?

Other ideas to consider
- Confirm limiting factor by using CISER's service to help tune where to invest (cores, RAM, hard drives space).
- Cut down on hard drive space by using file server space, in certain situations.
- Merge your investment into an existing cluster. Shared resources cost much less than standing up your own, small cluster.
- Confirm operational value of a single, "powerful enough" system (say, most large jobs done in 24 hours or less), vs. multiple, less powerful systems.
