Mar 10, 2022: Do you need fast x86_64 cores? Certain Limulus models now support the twelve core Ryzen 9 5900x and sixteen core Ryzen 9 5950x! This change brings the total number of physical cores to 64 for model 212 (128 threads) and an astounding 128 physical cores on model 1212 (256 threads). These processors are specified ro run at 105 Watts TDP and do not fit into the Limulus power/heat envelope. However, they have been configured for ~65 Watts TDP using a lower power threshold (essentially slightly down clocking the max frequency). Our tests indicate a maximum performance decrease of only 6%. In many cases the decrease is much less. Add our internal 25 GbE Ethernet option to these systems and create a massive parallel cluster next to your desk within the classic Limulus low noise, heat, and power envelope. This capability is offered on select AMD Ryzen 5000 (Zen-3 ) Limulus HPC systems (Hadoop systems coming soon). Contact us with your questions and configuration needs.

Nov 9, 2021: We are happy to announce the availability of our AMD Ryzen 5000 (Zen-3 ) Limulus HPC systems (Hadoop systems coming soon). Like the previous Zen-2 (Ryzen 3000) systems, models are available with 24, 32, and 64 cores and use ECC memory. The new Ryzen 5000 systems now offer faster Zen-3 cores, DDR4-3200 ECC memory, and NVMe over PCI-4 for improved main node storage throughput. The lower priced Ryzen 3000 (Xen-2) systems will still be available for a limited time.

Mar 18, 2021: Beowulf and cluster maven Jeff Layton wrote a great article entitled Desktop Supercomputers: Past, Present, and Future in HPC Admin. In the article he discusses Limulus systems as a current option for desktop (actually desk side) supercomputing. Jeff's coverage is always complete and very thorough (and he has published quite a number of classic cluster articles on Cluster Monkey). As 2021 progresses, expect more exciting advances from Limulus Computing.

Oct 6, 2020: Limulus V2 now has additional 3.5 inch drive bays. This change allows more spinning hard disk (HDD) storage for both NFS and HDFS (Hadoop Distributed Filesystem). The new Hadoop/Spark Data Analytics cluster (Model 452) supports up to 112 TBytes of raw HDFS storage using enterprise-level HDD drives .

May 29, 2020: One feature that was not mentioned in the previous announcement is the availability of 25 Gigabit Ethernet (25 GbE). The new 25 GbE option is available on base models 102, 202, 302, and 402 and comes standard on models 1202 and 1302.The price to upgrade is the same as the previous 10 GbE option. Benchmarks are forthcoming .

May 7, 2020: Limulus version 2 is here! This new series of machines delivers new features, lower prices, and more performance. The big news are the new micro ATX blades. All Limulus systems (desk-side and rack-mount) can now support almost any micro ATX based motherboard and processor (less than 80W TDP). In terms of processors, all systems now come with AMD Ryzen CPUs. This change brings two new features.

1. True next generation performance with more cores (up to 8 per processor), fast clocks (up to 3.6 GHz), and threads.
2. ECC memory (fully qualified with the Linux Kernel) is now standard on all systems

In terms of storage, we have increased our RAID storage options in both size (up to 54 TB of RAID6 on basic systems) and capability (systems now have six removable HDD bays). In terms of cost, all version 2 Limulus systems (with exception of a slight increase for the Hadoop model 1302) have a lower price AND more capabilities! Take a look at the new high-performance low-cost Limulus lineup.

Finally, we can optimize any system by component or geometry (with 3D printing). If you need specific hardware (i.e. Intel processors) please contact us directly.

Nov 17, 2019: Below are some pictures of the new low-cost Limulus V2.0 blades. These images below are prototypes, we will be posting updated images after SC19 in Denver. If you are attending the show, you can see the blades and how they fit into the LImulus case at Booth 996 (under Gidel on show map, look for Limulus Computing). We will also be showing our new Ryzen (Zen 2) nodes with ECC memory, headless booting, and lots of cores. We have also included some i7 nodes to show the "mix and match" capability of the new blades. Click for larger images. There is also a new master data sheet for all systems.
