Course Project Concurrent Programming 2019.1 (Computer Science program - UFCG)

Prerequisites

• Python 3.x
• Valgrind
• Golang
• Java
• Bash
• C

Running experiments

Experiment Protected vs unprotected

To run the first experiment first compile the following C scripts with the compiler you have available:

• code/list1/c-code/ex1/protected_ex1.c
• code/list1/c-code/ex1/unprotected_ex1.c

Now, simply run the Bash script code/utils/perf_exp.sh:

 bash ./code/utils/perf_exp.sh

• The resulting C.S.V file can be found at output/list1/ex1/perf_result.csv

Experiment Goroutines vs Java-Threads

Run the following Bash script to generate the mem profiling logs:

 bash ./code/utils/generate_mem_logs.sh

The generated logs can be found at output/list2/ex3/goroutine_javathread/

Now, run the following Bash script to process the logs into a C.S.V file:

 bash ./code/utils/format_all_logs.sh

• The Bash script invokes the Python script code/utils/format_mem_profiling.py. For further information about it, run:

 python ./code/utils/format_mem_profiling.py -h

Experiment on Collections' performance

Run the following Bash script to produce the results:

 bash ./code/utils/collection_perf.sh

• The resulting C.S.V file can be found at output/list1/ex5/report.csv
• The Bash script invokes the Java script code/list1/java-code/ex5/Main.java.

Built With

• Valgrind - Instrumentation framework for building dynamic analysis tools
  • Massif - Massif is a heap profiler. It measures how much heap memory your program uses
• ggplot2 - ggplot2 is a system for declaratively creating graphics, based on The Grammar of Graphics.
