Welcome to Russians Lab for the Cats Preparation
This is git repository (respect to Linus Torvalds) containing a number of code examples for researching input/output subsystem implementations in different computer languages (compilers and interpreters).
Due to very small size of the tested code examples, it is quite fair to compare compilers and interpreters in the single test set.
Currently, we explore how native I/O operations work
for each system under examination on re-implementation of the
GNU cat utility.
For the sake of performance, if it's possible, we use functions which operate on big blocks of data.
Utility strace or its analogs can be used to explore system
calls of executing programs.
To analyze computation systems based on virtual machines
with bytecode execution (e.g. JVM, BEAM, Parrot), a command
strace can be called with the -f flag.
