PI_Calculation_with_multhreading

Calculation PI with Multi-threading by using of Taylor Series

Write a multithreaded code in either C or Java that computes the pi number using Taylor series. Each compute-node will compute the part of the Pi number. Shortly you should decide on the decomposition of the following task. Pi/4 = +1/1 - 1/3 + 1/5 - 1/7 + 1/9 -...

Create a thread:

pthread_created(&workers[i],NULL,runner,&rng); pthread_join(workers[i],NULL);

Thread Runner:

Each runner calculates partial sum of Talyor series void runner(voidargs);

Determine dominator:

int denominator = (idx *2 + 1) * (int)pow(-1.0 , (double)idx);

Build:

gcc -pthread -o output pi.c –lm

Run :

./output
