Jan 27, 2025Priory-based schedulling
The goal is to design the processor scheduler for the new VenanciOS operating system. For this purpose, a preemptive algorithm has been devised with dynamic priorities between 0 and 31, where low numbers indicate low priority and high numbers indicate high priority. Processes always start with a fixed priority of value 15. If their quantum is exhausted, their priority decreases by one unit (at least to the value 0) and, if the process does not exhaust and is ejected, it remains with the same priority. If the process goes to sleep waiting for a resource, when it wakes up it increases its priority (boosting), depending on the type of resource, according to the following table:

Dec 9, 2024Running a local webserver with the big file to download
In the downloader practice we are told to download a big file using several processes working each on a different range of this big file. The file used as an example is hosted in a machine which IP is not reachable from Eduroam network. To overcome this, it is really easy to spin a webserver locally and use it to test our practice implementation.
