WARPLab 7: Benchmarks

In order to get a better understanding of WARPLab performance, we have added wl_benchmark so that you can perform some basic performance testing on WARPLab setup.

For the WARPLab 7.3.0 release, we have provided some Ethernet performance benchmarks since one of the biggest bottlenecks is moving data into and out of the node.

Ethernet Performance

As part of our on-going development to make WARPLab better and faster, we have introduced a new Transport (ie, the WARPLab MEX UDP Transport​) to boost communication performance between a host and a node. For more information on how to install and set up the WARPLab MEX UDP Transport, please refer to the QuickStart Guide.

Hardware and Software

• Netgear ProSafe 5-port Gigabit Desktop Switch (GS105)
• PC Hardware
  • Dell Optiplex 790
  • Intel Core i7-2600 3.4 GHz
  • 16 GB RAM
  • Window 7 Professional SP1 64-bit
  • Intel 82579LM Gigabit Network Connection
    • Configured to support Jumbo Packets of up to 9014 Bytes
• PC Software
  • Matlab 7.12.0 (R2011a)
  • Microsoft Visual C++ 2010 Express (compiler for MEX)
  • Microsoft Windows 7 SDK

Procedure

• Download Reference bit stream w/ iMPACT
• Open MATLAB
  • Set current folder within MATLAB to the M_Code_Reference folder of the appropriate WARPLab release
  • Run the following commands
    • wl_setup
      • NOTE: This allows us to configure the Transport type and the Ethernet Packet Size
    • nodes = wl_initNodes(1)
    • results = wl_benchmark( nodes, 'write_iq', 10000, 'max' );
    • results = wl_benchmark( nodes, 'read_iq', 10000, 'max' );
