Various Limulus Benchmarks
HPL Performance
- 200.3 GFLOPS (Raw HPL Results)
- 58% of Peak (3.3GHz * 4 cores * 8 FLOPS/cycle) + (2.5Ghz * 12 cores * 8 FLOPS/cycle) = 345.6 GFLOPS Peak
- Hardware Specification
Hadoop
Presentd a tutorial on Hadoop recently and used my original Limulus to demonstrated a four node Hadoop cluster. Some of the hardware is actually quite old. The nodes have a single dual core E6550, with 4 GB RAM, with 64MB SSD. The head node was a quad-core SandyBridge? (i5-2400S) with 4 GB RAM, 64MB SSD and .5 TB of RAID. Connections were using the crappy consumer based Realtek GigE Ethernet controllers on the nodes. Overall it worked well. I plan on making a Hadoop VNFS so that it is possible to boot the nodes into Hadoop. Used the Hortonworks HDP for the Hadoop install.
