1Ģ In order to prepare for this study we also researched what claims were made about each operating system and how they differ, what replacement and scheduling algorithms each operating system was published as using, and any prior comparison data that had been collected in this area. This computer was recently purchased by the Olin College Advanced Computing Lab, for which we are very grateful.

We were running Mac OS X and Darwin on the Mac side and Ubuntu Linux on the Linux side. We did preliminary testing for the experiments on a Blueberry imac clipping at a brisk 350 MHz with 512MB of RAM, and officially ran the experiments on a brand new Mac mini with a 1.25GHz processor, also with 512MB of RAM. Of particular note in this experiment is our ability to test the two operating systems on the same piece of hardware, an ideal situation for analyzing algorithms and OS overhead irrespective of hardware power.
Since these were areas we had discussed in class, we were relatively confident we could devise means of testing each operating system s efficiency in them. Each of these components are internal choices made by the operating system that the common user is not aware of, but each can have an important effect on the wait time perceived by the user. Specifically, we ran microbenchmarks to compare I/O performance, virtual memory page replacement, and disk cache replacement in Darwin and Linux. In other words, does the UNIX of a Macintosh perform equally as well as a Linux OS on the same hardware, or is one fundamentally superior? We decided to explore operating system algorithms for common computer necessities.

Differences were apparent in the results, and we wanted to learn whether the differences were hardware or software specific. The idea for the project came about from completing group homework assignments in the Software Systems course where one team member performed tests on the UNIX side of the Mac and the second team member performed them on the school s provided distribution of Linux. Nonetheless, we have undertaken the feat of matching key components of two flavors of UNIX: Darwin, the underpinnings of Mac OS X (based on FreeBSD) and Ubuntu Linux, running the typical Linux kernel both operate on the PowerPC processor. Introduction Comparing computer operating systems is hardly a new pastime, and UNIX is hardly a new operating system.
In conclusion, we analyzed the data we received from the above experiments, in a first order attempt to determine some degree of operating system superiority for the attributes mentioned. We tested this particular situation by incrementally consuming memory using malloc until it was shut down by the operating system. To test memory duress response, we exposed the kernel to malignant processes and analyzed the resultant data. In addition, we examined disk cache behavior by attempting to overflow the cache with junk data. To exercise file I/O handling we examined the repeated creation of small text files.

The virtual machine 'Ubuntu Server' has terminated unexpectedly during startup with exit code 1 (0x1). Here is the error I get trying to launch my Ubuntu VM on 6.1.10.įailed to open a session for the virtual machine Ubuntu Server. While it will be macOS 11 (it was released as a developer beta as 10.16), macOS Big Sur seems to have some Kernel extension changes that i think will require Virtualbox fixes.
