CFD Online Hardware Forum!
- SPEC - Standard Performance Evaluation Corporation
- The SPECfp benchmarks
are reasonably relevant for CFD applications. You can find recent benchmark
results for a wide range of hardware published on their web-site. Highly
- ANSYS Fluent Benchmarks
- A wide range of typical industrial CFD cases benchmarked on many different
hardware platform with the Fluent solver. This is a very good and current
resource. Highly recommended!
- ANSYS CFX Benchmarks
- A few benchmarks using CFX.
- The Performance Database Server, netlib
- A database with benchmark results. Has been online for a long time but
it is not updated very frequently.
News and Reviews
- the Inquirer
- Daily news from the PC industry. If you want to stay up do date with the
developments in the PC industry this site is very useful - has many inside
- The Register
- One of the largest news-sites in the PC industry. Updated all the time.
The quality can be a bit varying but they never miss anything.
- Publisher of leading magazines like PC Magazine, Computer Shopper, ...
Has a very large and nice web site.
- This amazing site, started in 1997 by a high-school student, has grown
into one of the leading hardware review sites on the net.
- X-bit Laboratories
- A very good hardware review site originating from Russia.
- Tom's Hardware Guide
- Reviews of PC hardware. For a long time this was the leading independent
hardware test site on the net. In recent years their quality has fallen a
bit though and there are probably better places to look for reviews today.
- Dell Computer Corporation
- The leading vendor for Intel based hardware - usually good price, quality
and support. Dell grew very quickly for many years but has stalled a bit lately.
- HP Compaq
- One of the leading workstation vendors. Sells workstations based on Intel
processors and their own PA-RISC processors running HP-UX. HP has had strong
position in the scientific computing area for a long time and merged with
Compaq recently. Will migrate to IA-64 in the future.
- Intel Corporation
- Designs, manufactures and sells processors. PC's based on their IA-32 architecture
and workstations based on their new IA-64 architecture seem to be the main
future computing platforms - all workstation manufacturers are adopting the
IA-64 platform. The only real competitor to Intel in the processor market

Comparison of cluster software,
- A few examples of good pages about clusters on Wikipedia
Book: Engineering a Beowulf-style Compute Cluster
- A very nice introduction to the art of building compute clusters. Written
by Robert G. Brown.
Cluster Design and Setup
- Another very nice introduction to the art of building compute clusters.
Written by Amit Jain.
CFD Test Solver
- A simple parallel code which uses LAM/MPI. Suitable for cluster benchmarking.
Free to download and use.
Software collections and entire distributions aimed at cluster management. Some are free and some cost money.
- OSCAR - Open Source Cluster Application Resources
- A collection of open-source cluster tools. This is an attempt to standardize
a whole suite of cluster tools. Looks very interesting.
- A free distribution aimed at HPC clusters. Rocks and OSCAR are the two main players here as far a we are aware.
We are not sure which one is best. Please give us your opinion if you try them!
- Penguin Computing, Scyld Clusterware for HPC
- Sells cluster management software focused on large cluster applications. Scyld was
started by Donald J. Becker, one of the pioneers in Beowulf clusters. Scyld was
later bought by Penguin Computing.
- Platform Computing
- Sells cluster management software.
Most clusters are buildt around Linux. Here are a few of the most popular distributions.
- RedHat, Inc.
- RedHat is the leading Linux distribution and it is the operating system
most frequently used on clusters today.
- A free version of RedHat Enterprise Linux. This is what cfd-online.com runs on :-)
- Scientific Linux
- Another free distribution based on RedHat Enterpise. Focused on scientific computing and managed by Fermilab and CERN.
- SuSE is the second largest Linux distribution. The free version is linked here,
there is also an enterprise SuSE version that costs money. A nice alternative if you
for some reason don't like RedHat.
- A linux distribution based on Debian that has become popular over the last few years.
A few selected cluster vendors. Most people build their clusters using hardware from
normal hardware vendors, but here are a few examples of vendors focused on HPC cluster hardware.
You might also try the free Cluster
. They say they
will submit your RFQ to 30+ vendors. We haven't tried it. Looks like a nice service
though. Please email us
if you do try this service.
- PSSC Labs
- Sells pre-configures beowulf clusters. Has an online cluster configurator
which you can use to request a quote.
- Penguin Computing
- Has been selling pre-packaged clusters based on Linux for a long time.
Has a good reputation.
- Atipa Technologies
- Sells linux clusters for high performance computing applications.
- SGI used to be the leader in scientific computing and visualization hardware, but as
Linux and Beofulf clusters together with very good PC based grapics from NVidia and AMD/ATI
took away SGI's market they went belly up. However, in 2006 SGI re-emerged and for the moment
SGI are doing well. SGI is now very focused on cluster computing and have bought several
cluster vendors. They also recently bought OpenCFD, so you will probably soon be able to buy
a pre-configured cluster from SGI with OpenFOAM pre-installed.
General Purpose Grapics Processing Unit (GPGPU)
