##### MARIN MARIUS DANIEL 332CC
## [Tema1 - APD](https://gitlab.cs.pub.ro/apd/tema1)
### Ideea de baza
* crearea unei structuri ce inglobeaza argumentele
necesare thread urilor si transformarea functiilor
secventiale intr-o singura functie in care vor fi
rulate toate thread urile
### Implementare:
* s-au paralelizat urmatoarele 3 functii:
1. `rescale_image`
2. `sample_grid`
3. `march`
### Pentru
* rescale_image
- s-a impartit prima iteratie in intervale pentru fiecare thread
- se asteapta toate thread urile sa termine executia pentru a nu crea un race condition atunci cand reactualizam imaginea
* sample_grid
- se impart in intervale pentru fiecare thread iteratiile
* march
- se imparte iteratia in intervale pentru fiecare thread
* thread uri
- s-au creat 2 structuri (una care contine informatiile
necesare si independente de thread) si una care contine
informatiile caracteristice fiecarui thread(id) + cealalta
- cu ajutorul ei se transmite argumentul fiecarui thread
### Mai multe detalii se regasesc in cod.
