Vaccine Monitor app implemented in C with system Programming techniques.Projects implemented as part of the course Syspro K24

Project 1

Vaccine Monitor app created using data structures in C, like bloom filter, linear probing hashtable, linked lists,skip lists etc.

Create input dir:

bash testFile.sh info/virusesFile.txt info/countriesFile.txt input_dir x y

where ,x=0|1 ,0 doesn't allow duplicates while 1 does. y is the numer of records you wish to create eg.:1000

Compile

To create new input dir and compile the program simultaneously, write in your terminal:

make all DUP_FLG=x RECORDS=y

where ,x and y are used as described above

To compile ony the project:

make

To delete the objective files:

make clean

To run the project and check memory:

valgrind --leak-check=full ./vaccineMonitor -c input_dir/inputFile.txt -b bloomsize

Project 2

Based on the 1st project we go one step further and we implement the app using signal handlers and named pipes

Create input dir:

bash ./create_infiles.sh input_dir/inputFile.txt input_dir2 numfiles

where numfiles equals to the number of files per country dir

Compile

To create new input dir and compile the program simultaneously, write in your terminal:

make script NUM_FILES_PER_DIR=x

where numfiles equals to the number of files per country dir

To compile ony the project:

make

To delete the objective files:

make clean

To run the project and check memory:

valgrind --leak-check=full --show-leak-kinds=all --trace-children=yes -s ./travelMonitor -m 3 -b 100 -s 1000 -i input_dir

Project 3

Last version of the Vaccine Monitor app.Based on the structure of the 1st project, the app is now implemented based on the concept of "one client - multiple servers " using sockets and threads

Create input dir:

bash ./create_infiles.sh input_dir/inputFile.txt input_dir2 numfiles

where numfiles equals to the number of files per country dir

Compile

To create new input dir and compile the program simultaneously, write in your terminal:

make script NUM_FILES_PER_DIR=x

where numfiles equals to the number of files per country dir

To compile ony the project:

make

To delete the objective files:

make clean

To run the project and check memory:

valgrind --leak-check=full --show-leak-kinds=all --trace-children=yes ./travelMonitorClient -m 3 -b 100 -c 2 -s 1000 -i input_dir -t 3 < instructions.txt
