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

The Limulus™ Personal HPC workstation provides industry leading price-to-performance with a personal low power and noise profile. The Limulus Model 100 (with Skylake processors) can deliver 658.3 GFLOPS of double precision CPU performance (as measured by HPL Benchmark using 10GbE) in a quiet and cool desk-side workstation package. Each Limulus packs four standard Micro-ATX motherboards into a standard PC case supported by a single high efficient powersupply (one wall plug).

Power to the three worker nodes is controlled by the master using a simple software interface. Each of the additional nodes can be powered-on when needed by the user or by the resource scheduler. At idle, with nodes off, a Limulus consumes a mere 60 Watts of power.

"Day One, Ready To Run" Turn-key Powerhouse With Support

Each Limulus comes with a fully installed Linux HPC cluster software stack. The system is ready for use on first "power-up." There is no other configuration needed other than user/site customization. All Linux software is fully 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:

  • Node management with pdsh and whatsup
  • Includes simple node power control commands
  • 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
  • Environment Modules are automatic preserved (or cleared) across node logins
  • Email from nodes, used by scheduler
  • Complete Open Grid Scheduler (SGE) ready to run configuration
  • Full Ganglia integration (including processor temperatures)
  • Local On-line documentation (example)
  • Web based Limulus Manual

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