Handling Big Data on Modern Computers: A Developer's View

Francesc Alted

Audience level:


Nowadays computers are being designed quite differently as they were made more than a decade ago; however, very little in software architecture has changed in order to accommodate for the changes in the hardware architecture. During my talk I am going to describe which those fundamental changes are and how to deal with them from the point of view of a long-time developer.


During the last decade the evolution of the computers has been much different than before. Instead of seeing acceleration in CPU clock speeds we are seeing more cores in CPUs, and instead of having plain simple architectures with a CPU, memory and hard disk, we are seeing computer facilities with several CPUs, several levels of caches and several persistent layers of storage.

It is unfortunate that not many libraries are being designed nowadays with this shift in mind. My intention is to explain how to tackle with this efficiently during the making of libraries for handling big datasets. We will see that the election of a good language is important too, and how Python, complemented with others (like Cyhton, C or Julia), is a good match for this.
