Perf-On-STAMP

Code Modified

Replace or link stm_internal.h in tinySTM/src (stm_delay entry)
Replace or link thread.* in STAMP/lib/ (thread affinity)

Perf Probe and Run

Usage

Run Under STAMP directory. Make sure to specify file name in command argument.
Modify argument nthreads to set thread number.
ex. $./perProbeRun.sh CTL_BACKOFF
The file name will be like 2021_06_17_CTL_BACKOFF
If not specified, the file name will only contain date, and older version will be replaced.
You will be asked to select Perf Status[0] or Perf Record[1]
Perf Status only shows Perf console, Perf Record generates perftrace in the ptrace directory.

Convert perf data to Visualizer data

Run convert.py to convert perf data to visualizer data.
The scrip implements state transition as follow:

Usage

Provide your perf data path as sysarg.
ex. $ python Convert.py ptrace/2050_12_25_ETL_DELAY
Visualizer data with sufix .log file will be generated.

• Tag 0 indicate start to delay
• Tag 1 indicate delay entry to delay return
• Tag 2 indicate commit return

STAMP

Written by Tonie Lai with a few modified.
Modify argument THREAD_NUM to set thread number.
To avoid cache locality, which could greatly affect execution time, each stamp application is take turns to execute.
Run Under STAMP directory and make sure to specify file name in command argument.
ex. $./stamp.sh ETL_BACKOFF
Log file will be generate under $STAMMP_BASE/recore/run_log directory

Rec.py

Calculate the average execution time and plot the result.
You can refer to matplotlib to change color of the cylinder.

Usage

Provide your log file path as sysarg.
ex: $ python Rec.py record/run_log/2050_12_25_ETL_SUICIDE
You’ll see summary.txt under the log file and a pop out plot window.
