Subject: [Beowulf] Building new cluster - estimate

..
I am in process of upgrading computational facilities of my lab and
considering of building/purchasing 40 node cluster. Before contacting
vendors I would like to get some understanding how much would it cost. The
major considerations/requirements:
1. newest Intel quad-core CPUs (Opteron quad-core cpus are out of question
due to ridiculous pricing), good balance of price/performance
Hmm, what is "ridiculous about Opteron pricing?
In HPC work one generally needs a XEON clocked about 20% to 25% faster
than an Opteron for equivalent performance.
Mainly due to the limitations of memory bandwidth of the XEONs.
Current CPU pricing comparison:
BX80574E5410A Intel Quad-Core Xeon E5410 / 2.33 GHz ( 1333 MHz ) -
LGA771 Socket - L2 12 MB ( 2 x 6MB ) - Box $322.00
BX80574E5420A Intel Quad-Core Xeon E5420 / 2.5 GHz ( 1333 MHz ) -
LGA771 Socket - L2 12 MB ( 2 x 6MB ) - Box $393.00
OS2350WAL4BGHWOF AMD Third-Generation Opteron 2350 / 2 GHz - Socket F
(1207) - L3 2 MB - PIB/WOF $292.00
OS2352WAL4BGHWOF AMD Third-Generation Opteron 2352 / 2.1 GHz - Socket
F (1207) - L3 2 MB - PIB/WOF $366.00
BX80574E5430A Intel Quad-Core Xeon E5430 / 2.66 GHz ( 1333 MHz ) -
LGA771 Socket - L2 12 MB ( 2 x 6MB ) - Box $557.00
BX80574E5440A Intel Quad-Core Xeon E5440 / 2.83 GHz ( 1333 MHz ) -
LGA771 Socket - L2 12 MB ( 2 x 6MB ) - Box $833.00
OS2354WAL4BGHWOF AMD Third-Generation Opteron 2354 / 2.2 GHz - Socket
F (1207) - L3 2 MB - PIB/WOF $525.00
OS2356WAL4BGHWOF AMD Third-Generation Opteron 2356 / 2.3 GHz - Socket
F (1207) - L3 2 MB - PIB/WOF $796.00
2. reasonably fast interconnect (IB SDR 10Gb/s would suffice our
computational needs (running LAMMPs molecular dynamics and VASP DFT codes)
Or Myrinet. Bandwidth is usually unimportant, but latency usually is.
So called "memfree" IB cards are rarely any kind of bargain for this use.
