Comparing Systems Using Sample Data
Operating System and Process Monitoring Tools Arik Brooks, [email protected] Abstract: Monitoring the performance of operating systems and processes is essential to debug processes and systems, effectively manage system resources, making system decisions, and evaluating and examining systems. These tools are primarily divided into two main categories: real time and log-based. Real time monitoring tools are concerned with measuring the current system state and provide up to date information about the system performance. Log-based monitoring tools record system performance information for post-processing and analysis and to find trends in the system performance. This paper presents a survey of the most commonly used tools for monitoring operating system and process performance in Windows- and Unix-based systems and describes the unique challenges of real time and log-based performance monitoring.

Morpho-Syntactic Interactions Between V and C in Romance1
Dialectologia. Special issue, V (2015), 293-319. ISSN: 2013-2247 Received 7 August 2015. Accepted 26 September 2015. MORPHO-SYNTACTIC INTERACTIONS BETWEEN V AND C IN ROMANCE1 Ángel J. GALLEGO Universitat Autònoma de Barcelona [email protected] Abstract This paper discusses a series of morpho-syntactic (a)symmetries that emerge in the vP and CP levels of different Romance languages. The (a)symmetries considered indicate a P or D oriented nature for specific functional heads placed in the vP and CP domains, an idea that has been at the forefront of micro-parametric studies ever since the 80s (cf. Kayne 1984, 2000; Uriagereka 1995). The consequences of this investigation for the status of parameter theory are further considered (cf. Chomsky 1981; Baker 2001; Biberauer 2008; Kayne 2000; Picallo 2014) and the study of the lexicon, arguably the main locus of linguistic variation (cf. Halle & Marantz 1993; Hale & Keyser 1993; Starke 2014; Uriagereka 2008).

Windows NT Network Management: Reducing Total Cost of Ownership - 9 - Performance Monitoring
Windows NT ...: Reducing Total Cost of Ownership - Chapter 9 - Performance Monitorin Page 1 of 13 [Figures are not included in this sample chapter] Windows NT Network Management: Reducing Total Cost of Ownership - 9 - Performance Monitoring AN OLD ADAGE SAYS, "IF YOU can’t measure it, you can’t manage it." Even if you can measure something, how can you tell if your changes are making a difference if you don’t have baseline information? It’s important to monitor a server’s or work- station’s performance to maximize your investment in these tools. If a user complains that her computer is too slow, you often need more information to fix the problem. For example, if the problem is loading Web pages on a computer using an analog modem, the modem is probably limiting the system’s performance. However, if the computer is an older model, certain operations may wait for the CPU to finish processing. In this case, a complete system upgrade may be the best solution. The usefulness of performance monitoring goes far beyond handling user expectations. A network and systems administrator can use information obtained by analyzing the operations of existing hardware, software, and networking devices to predict the timing of upgrades, justify the cost of replacing and upgrading devices, and assist in troubleshooting. Performance monitoring ultimately reduces TCO and is a vital part of managing any IT environment. Performance monitoring helps answer important questions about your current environment. For example, you may want to know which activity specifically uses the most resources in your environment. If you determine that it is loading Web pages, then upgrading the RAM or the CPU speed of client machines may not help much. -

Porting the QEMU Virtualization Software to MINIX 3
Porting the QEMU virtualization software to MINIX 3 Master's thesis in Computer Science Erik van der Kouwe Student number 1397273 [email protected] Vrije Universiteit Amsterdam Faculty of Sciences Department of Mathematics and Computer Science Supervised by dr. Andrew S. Tanenbaum Second reader: dr. Herbert Bos 12 August 2009 Abstract The MINIX 3 operating system aims to make computers more reliable and more secure by keeping privileged code small and simple. Unfortunately, at the moment only few major programs have been ported to MINIX. In particular, no virtualization software is available. By isolating software environments from each other, virtualization aids in software development and provides an additional way to achieve reliability and security. It is unclear whether virtualization software can run efficiently within the constraints of MINIX' microkernel design. To determine whether MINIX is capable of running virtualization software, I have ported QEMU to it. QEMU provides full system virtualization, aiming in particular at portability and speed. I find that QEMU can be ported to MINIX, but that this requires a number of changes to be made to both programs. Allowing QEMU to run mainly involves adding standardized POSIX functions that were previously missing in MINIX. These additions do not conflict with MINIX' design principles and their availability makes porting other software easier. A list of recommendations is provided that could further simplify porting software to MINIX. Besides just porting QEMU, I also investigate what performance bottlenecks it experiences on MINIX. Several areas are found where MINIX does not perform as well as Linux. The causes for these differences are investigated.
