• wperf-relay is later called “relay”.

• wperf-gui is later called “GUI”.

Description of Phase 1

...

wperf

• Building initial GUI (wperf-gui).

  • Building widget to select host (IP/URL/port) to connect to.

  • Building widget to save/load host information.

  • Building widget to prepare list of events and event groups for wperf stat command line option -e <events>

    • Build list of CORE events and event groups.

    • [Nice-to-have]Widget would also prepare list of DSU and DMC events.

    • Make sure events and groups are sent to relay (as protocol payload) in the same order as defined by user. Please note that group numbers are assigned by wperf from left to right. For example:

      • -e {inst_spec,vfp_spec},ase_spec,{dp_spec,ld_spec,st_spec},br_immed_spec,crypto_spec

        • group 0 (g0) is {inst_spec,vfp_spec}

        • group 1 (g1) is {dp_spec,ld_spec,st_spec}

  • Building widget to prepare list of metrics wperf stat command line option -m <metrics>

  • Listing all available events and metrics (wperf list) - for example separate tab.

  • Listing additional data about host (wperf test) - for example separate tab.

  • Listing of wperf version number (wperf -version -json).

    • For example in modal window “about” and

    • in bottom status bar.

  • Support visualization (table) of output of wperf stat -e <events> -m <metrics> -c <cpu_list> sleep <N>.

• Support counting model (wperf pov) JSON output for (below all done):

  • wperf stat -e <events>

  • wperf stat -m <metrics>

  • wperf stat -e <events> -m <metrics>

  • Command line option -c <cpu_list>

  • Command line option sleep <N>

• Building first version of relay.

• Building first version of GUI.

• Establishing common protocol between relay and GUI.

  • Event and metrics list fetch. Output from wperf list -json.

  • Host system and wperf application configuration. Output from wperf test -json.

  • Counting with wperf stat ... -json.

  • Basic “real time” wperf stdout logging in GUI.

    • We would like to see wperf screen output in GUI during counting execution.

• Basic error handling by relay and GUI.

  • Relay-GUI protocol must be able to send error information to GUI.

  • Relay-GUI protocol must provide “busy” state to GUI from relay.

  • GUI should report errors but is not responsible to error recovery of the relay and wperf.

  • Note: relay will execute and have control over wperf process and will be responsible for executing, stopping and error handling wperf.
