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 ¶

Presented a tutorial on  Hadoop recently and used my original Limulus to demonstrate 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 and a 64MB SSD. The head node has a quad-core Sandy Bridge (i5-2400S) with 4 GB RAM, 64MB SSD, and .5 TB of RAID1. Connections were using the mediocre 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. The following are results of the TestDFSIO benchmark (tests the Hadoop File System)
