• Philip Aziz - Calculating Prime Numbers

Only the inner loop would be possible to Parellelize but would still require to validate 1 prime number at a time due to need to validate against previous prime numbers.

while (count < n){

               flag = 1;
               i = 1;
               checkKey = int((sqrt (prime))+1);
               //checks prime numbers for divisible values
               while(primes[i] < checkKey and flag){
                       if ((prime % primes[i])==0){
                               flag = 0;
                       }
                       i++;
               }
               if(flag){
                       primes[count] = prime;
                       count++;
               }
               prime +=2;
       }
