Curve fitting of Monod growth/degradation equations to the experimental data

Why is there barrier() in KCOV code in Linux kernel?

QUESTION

Curve fitting of Monod growth/degradation equations to the experimental data

Asked 2020-Jun-16 at 12:26

So the problem that is being faced here is the curve fitting of the Monod equations to the experimental data. The model of bacteria growth and degradation of the organic carbon looks like this:

dX/dt = (u * S * X )/(K + S)

dS/dt = ((-1/Y) * u * S * X )/(K + S)

These equations are solved using the scipy odeint function. Results after integration are stored into two vectors, one for growth, and the another one for degradation. The next step is to curve fit this model to the experimentally observed data and estimate the model parameters: u, K and Y. Once the code is run, the following error is produced:

The result of f() needs to have the same shape as the experimental data you feed into curve_fit as third parameter. In the last line of f() you just take the t = 0s value of the solution for both ODEs and return that, but you should return the complete solution. When fitting several sets of data at once using curve_fit, just concat them (stack horizontally), i.e.

Why is there barrier() in KCOV code in Linux kernel?

Asked 2020-May-17 at 12:55

In Linux KCOV code, why is this barrier() placed?

Without barrier(), the compiler would be free to access t->kcov_area before t->kcov_mode. It's unlikely to want to do that in practice, but that's not the point. Without some kind of barrier, C rules allow the compiler to create asm that doesn't do what we want. (The C11 memory model has no ordering guarantees beyond what you impose explicitly; in C11 via stdatomic or in Linux / GNU C via barriers like barrier() or smp_rb().)

As described in the comment, barrier() is creating an acquire-load wrt. code running on the same core, which is all you need for interrupts.
