== What is the Limulus Project? ==
Limulus is an acronym for '''LI'''nux '''MUL'''ti-core '''U'''nified '''S'''upercomputer. The Limulus project goal is to create and maintain an open specification and software stack for a ''personal workstation cluster''. As "edge of cloud" computing becomes more important, these systems are designed to offer HPC, Big Data (Hadoop-Spark), and Deep Learning in almost any location. Ideally, a user should be able to build or purchase a small ''personal workstation cluster'' using the Limulus reference design and low cost hardware. In addition, a freely available turn-key Linux based software stack will be created and maintained for use on the Limulus design. A Limulus is intended to be a local ''workstation cluster platform'' where users can develop software, test ideas, run '''edge applications''', and teach HPC methods. Consult the following draft of a Linux Magazine [http://limulus.basement-supercomputing.com/attachment/wiki/WikiStart/Limulus-Nov-2007-draft.pdf?format=raw Limulus Article] (pdf) for more information. The Limulus idea actually came from the 2005 [https://www.clustermonkey.net/Projects/the-value-cluster-cheaper-better-faster.html AMD Value Cluster Project].
'''Pre-built, tested and supported commercial Limulus systems''' are available from [http://basement-supercomputing.com/ Basement Supercomputing]

== Project Status ==
'''August 22, 2019:''' A new white paper posted on [https://www.clustermonkey.net/Site-News/new-documents-available-to-site-users.html Cluster Monkey] (simple reg required). In the paper the cost of a commercial Limulus (both HPC and Hadoop version) is carefully compared to similar EC2 instances. Striking results.
'''February 03, 2019:''' More commercial news. First, tested systems with six-core/six-thread Xeon E-2176G (these chips run at 80W vs 65 W for i5,i7, Limulus cooling works) Check out more news about Xeon/ECC Limulus, rack-mount options and more at [http://basement-supercomputing.com/ Basement Supercomputing].
'''November 12, 2018:''' We are getting ready to release the STL files for 3D printing brackets for the tower Limulus machines (delayed until fall 2019). However, you can get the SC19 slides describing our 3D printed Limulus case at [https://www.clustermonkey.net/Site-News/new-documents-available-to-site-users.html Cluster Monkey] (reg required) Check out [http://basement-supercomputing.com/ Basement Supercomputing], systems with new six-core i5-8600 and 6-core/6-thread i7-8700.
'''November 11, 2016:''' After a long silence, we have news. First, benchmarks for Coffee Lake (Intel) and Raven Ridge (AMD) will be available real soon. Second, [http://basement-supercomputing.com/ Basement Supercomputing], who sponsors this project, has converted all the metal brackets needed to place a Limulus system in a commercial case to 3D-Printed parts. They will also be releasing the files needed to print the parts to the community.
'''March 21, 2016:''' Limulus with Skylake (i7-6700, 256GB total system memory) hits 640.4 double precision CPU GFLOPS using HPL and 1 GbE (592.5 GFLOPS using 128GB total system memory). You can see the [wiki:LimulusBenchmarks Latest Results] for details. Pre-built machines delivering a new record setting $10.62/GFLOP can be purchased from [http://basement-supercomputing.com/ Basement Supercomputing]
'''February 3, 2016:''' Limulus with Skylake (i5-6500, 64 GB total system memory) hits 480.2 double precision CPU GFLOPS using HPL and 1 GbE (658.3 GFLOPS with 10 GbE!) . You can see the [wiki:LimulusBenchmarks Latest Results] for details. Pre-built machines delivering a new record setting $11.44/GFLOP can be purchased from [http://basement-supercomputing.com/ Basement Supercomputing]
'''May 19, 2014:''' Limulus does Hadoop! A 100 GB Terasort in 886 seconds (113 MB/sec). You can see the [wiki:LimulusBenchmarks Latest Results] for details. Pre-built machines running [http://hortonworks.com/hdp/ Hortonworks HDP] with
full [http://hortonworks.com/hadoop/ambari Ambari] install are available at [http://basement-supercomputing.com/ Basement Supercomputing]
'''April 9, 2014:''' New lighter, sleeker, cases with wheels. Check them out [http://basement-supercomputing.com/ Basement Supercomputing].
'''November 27, 2013:''' Limulus with Haswell (i5-4570S) hits 385.5 double precision CPU GFLOPS (HPL). You can see the [wiki:LimulusBenchmarks Latest Results] for details. Pre-built machines delivering a record setting $15.55/GFLOP can be purchased from [http://basement-supercomputing.com/ Basement Supercomputing]
'''November 12, 2013:''' Finally, that day is here, Limulus units are available from [http://basement-supercomputing.com/ Basement Supercomputing]. If you are attending SC13, come see a Limulus system (running Hadoop) in the Scalable Informatics booth number 1919. There will be a daily presentation entitled, ''Personal Big Data: The Apache Hadoop YARN Workstation and Beyond'' at the following times Tuesday: 5pm, Wednesday: 11am, Thursday: 1pm. And keep an eye on the [wiki:LimulusBenchmarks Limulus benchmark page].
'''June 26, 2012:''' The software stack is ready to go. All development is based on Scientific Linux 6.X (SL6). Both SRPMS and RPMS will be officially available in July. You can peak at the RPMS [http://basement-supercomputing.com/download/releases/sl/6/limulus/x86_64/RPMS/ here], but there may be some changes before the official release date. Plus, documentation on how to install these on top of SL6 will be made available as well.
