Diminishing returns of parallel processing
Intro It’s been a while without new entries here, as usual because I was busy one way or another. In keeping with the Master’s studies, one of my excuses is the homework for the “high performance computing” course. Recently we worked on OpenMP, and then with MPI. Both are cool and those that read this…

Iterative function calls with Reduce
Intro In many instances, the “Numerical Methods” will imply recurrent function calls. We demonstrated how to go about this using loops here. But I wasn’t satisfied with this approach (I did mention, I prefer the apply() family of functions over for loops…). The apply() wasn’t fit for it, but while digging a bit deeper into…

Higher Performance in R – Amdahl and Gustafson’s laws
Intro So I’m currently taking this course about “High Performance Computing”. This entry is not about that exactly: let’s face it, R is not the best option there 😀 But some concepts I touched in the past I thought I could summarise today (for example of past entries: here or here, and more links in the…
