They agree with me that fewer bigger parallel processors are better than many smaller processors connected with MPI. I.e., they like my priorities in this course.

3   Quantum computing ctd: Shor's algorithm

1. Factorize an int.
2. in BQP.
3. almost exponentially faster than best classical algorithm.
4. When I searched for the largest example, I found several inconsistent announcements in the last year or two.
   1. 1005973. There is some disagreement about D-wave machines.
   2. 21
   3. 35
   4. 56153 = 233 × 241.

5. Interesting about factoring:
