    A beautiful day to all primers, i have develloped a prime sieve base on Ulam for a Cuda Graphic Card. Results: constant ca 8.317.200 Primes / sec on a Cuda

      A beautiful day to all primers,

      i have develloped a prime sieve base on Ulam for a Cuda Graphic Card.

      Results:
      constant ca 8.317.200 Primes / sec
      on a Cuda graphic card Geforce 650 with 192 Cores

      there is a description of the algorithm and an implementation
      http://109.91.184.78/devalco/prime_sieve_ulam_vertical.pdf
      http://109.91.184.78/devalco/ulam_31.cu

      Perhaps there are some speedups possible.
      The algorithm is quite nice and i hope it is possible to understand the idea.

      I am interested in results on graphiccards with more Cores
      and improvements.

      Nice greetings from the primes
      Bernhard
