This is the Stress Test running on the completed Weenix toy operating system originally built by Brown University, which is used as the kernal source code of CSCI 402 (Operating Systems) class taught by professor Bill Cheng from USC Viterbi School of Engineering. Throughout the three kernel assignments for this class, two teammates and I filled in the functions that implement the processes and threads, S5FS File System and Virtual Memory modules that are necessary for this Unix-like operating system to work. Aside from the Stress Test, our implementation passed all the other tests such as those kernel assertions, memory test and fork bomb.
