A Cluster When You Need One, An Efficient Workstation When You Don't

The Limulus™ Personal HPC Edge workstation provides industry-leading price-to-performance with a personal workstation feel. The low power and noise profile allows Limulus systems to be located almost anywhere and remotely managed from everywhere. These turn-key appliances can be used for:

  • Local group/departmental compute server
  • Private/personal (secured/off-line) high-performance production cluster
  • Software development platform (own the reset switch)
  • Quick turnaround laboratory computing system
  • Factory floor data acquisition and analytics
  • Classroom and learning resource in almost any location, and more.

Each Limulus Model 1222 cluster packs eight standard Micro-ATX (μATX) motherboards into a standard PC case sharing a single highly efficient power supply (one wall plug). Designed for the office, lab, classroom, or shop, the mobile Limulus Edge cluster runs quiet and cool using a standard electrical service -- No Data center needed! Worker nodes are fully removable μATX blades with pluggable hot swap power (can be swapped while the rest of the system is running).

The master controls the power to the seven worker nodes using a simple software interface. The user or the resource scheduler can power on each of the additional nodes as/when needed. At idle, with nodes turned off, a Limulus consumes approximately 60 Watts of power.

Extremely cost effective - pays for itself after 10-12 months of equivalent cloud usage. Ask about our white paper.

"Day One, Ready to Run": Turn-Key Powerhouse with Support

Each Limulus comes with a fully-installed Linux OpenHPC cluster software stack. The system is ready for use upon its first "power-up." There is no other configuration needed other than user/site customization. All Linux based software is open source (SRPMS available), integrated, and upgradable (via YUM/RPM). Each system comes with on-board basic documentation which is supplemented by an on-line manual.

The fully configured system includes the following capabilities:

  • OpenHPC 3.0 base install including libraries, MPI, GNU compilers.
  • Node management with Warewulf, pdsh, and WhatsUp
  • Utilities for adding/removing users, node power control, cluster load, and CPU governor states
  • GUI interfaces for adding/removing users and for node power control
  • Fully configured firewall, node log management, and replication using rsyslog
  • Automatic SSH key generation and propagation of users accounts on nodes
  • NAT configured on nodes for full LAN/Internet access and email
  • Full Ganglia integration (including processor temperatures)
  • Complete SLURM ready to run configuration
  • Environment Modules are automatic preserved (or cleared) across node logins
  • Local on-line documentation

A full year of Return to Depot hardware and 90-day software support is included with each system. Additional software support is available.
