Hello Bruno,

I have a few questions on the course you taught us yesterday:

1. Can the momentum balance equation for a Lagrangian tracer stated below be an example to an Embarrassingly Parallel Problem, as ever term in the equation is to be addressed separately?

M(d* v/*dt)= -M

*X*

**f**

**v**+

*T*_{a}+

*T*_{o}+

*T*_{i}+

*F*_{r}

**+**

*F*_{p}

2. In slide-24, when you said 'the serial part dominates asymptotically', did you mean lim_{P→∞} S =
1/f = 1 + T_{p}/T_{s }? Would you kindly elaborate mathematically it a little further, please?

3. In slide-28, how did a 42% processor usage yield a speedup =3.4, and a 72% usage derived a speedup = 5.8? How did you do this conversion?

And have you already assigned the work to us? I am not being able to reach it by clicking on the assignment button.

Hope to see you tomorrow.

Thanks and best regards,

Madhurima.
