Here a short summary of today meeting with Lucio.
4 1 Soon Jun
5 1 Soon Jun
1.  access to the repository
6 1 Soon Jun
     for the time being, use the private-key, but will try to switch to use kerberos when the port is open.
7 1 Soon Jun
     Lucio successfully pushed his updates (I/O related) to the repository and also added an item in wike page
8 1 Soon Jun
9 1 Soon Jun
2. new items on the wiki page
10 1 Soon Jun
    - Stepper accuracy: parameters involved  (by Lucio)
11 1 Soon Jun
    - Geant4 Particle Transportation (by Soon)
12 1 Soon Jun
13 1 Soon Jun
3. Items that we lightly touched but should be discussed in depth at the next meeting(s).
14 1 Soon Jun
    - how do we compare computing performance of QSS/Geant4 with a pair-basis? 
15 1 Soon Jun
      (i.e., deltaQ in QSS vs. deltaStep in Geant4 or the error size?)
16 1 Soon Jun
    - performance profiler (to understand performance of CPU and memory or to optimize codes later)
17 1 Soon Jun
    - we may try one more benchmarking example with little more complicated geometry
18 1 Soon Jun
      and a non-constant magnetic field (but still a simple polynomial)
19 1 Soon Jun
    - once we understand the basic performance, then should try QSS on a realistic experimental setup
20 1 Soon Jun
      (typical HEP detector and magenetic field map)
21 1 Soon Jun
    - how to integrate the QSS solver into the Geant4 framework ?
22 1 Soon Jun
    - how to validate physics results and stability
23 1 Soon Jun
    - how to vectorize/parallelize QSS or make it coprocessors (GPU/MIC) friendly
24 1 Soon Jun
    - and etc.
25 1 Soon Jun
26 1 Soon Jun
4. We will try to meeting in a week at the same time if there is no conflict.
