Ideal for Oracle database programmers and administrators using the UNIX platform. Shows readers how to optimize the performance of an Oracle8i database (the latest version of Oracle's world-leading database) running on any UNIX system.

It focuses on real world problems encountered by database 3/5(1). viii IBM Power Systems LC and LC Technical Overview and Introduction Gustavo Santos is an IBM Power Systems Consultant at IBM.

With asynchronous I/O, you can submit blocks 1, 2, 3, and 4 and then wait for all four blocks to complete. Because you gave the operating system all four I/O requests at once, it can act on all the requests in parallel.

The total response time is only the duration of the longest I/O of the four, rather than the sum of all four I/O durations. VAX Macro to C conversion Showing of messages.

VAX Macro to C conversion: Andrew Shaw: 6/23/19 PM: Hello world, We have a pile of now quite ancient VAX MACRO code that forms part of our OpenVMS business software which we now run on Itanium. Historically we needed the performance benefits that MACRO gave us, but these.

Windows NT is a family of operating systems produced by Microsoft, the first version of which was released on J It is a processor-independent, multiprocessing and multi-user operating system.

The first version of Windows NT was Windows NT and was produced for workstations and server was intended to complement consumer versions of Windows that Developer: Microsoft.

The Massbus is a high-performance computer input/output bus designed in the s by Digital Equipment Corporation (DEC). The bus was used by Digital to Vax I-O Subsystems book its highest-performance computers with magnetic disk and magnetic tape storage equipment.

The use of a common bus was intended to allow a single controller design to handle multiple peripheral. The most common I/O is digital I/O, commonly called general-purpose I/O, or GPIO. These are ports that may be configured by software, on a pin-by-pin basis, as either a digital input or digital output.

As digital inputs, they may be used to read the state of switches or push buttons, or to read the digital status of another device.

Comprehensive and convenient, the book focuses on the kernel of the VAX/VMS Version operating system: process management; memory management; the I/O subsystem; the mechanisms that transfer control to, from, and among these; and the system services that support and complement them.

The computer architecture of the TX control system (Fig. 1) The selection of the NI control system as a model for the new TEXTOR control system dictated the employment of a VAX as a central computer. Price performance com- parisons voted for a Cited by: 1.

To refine protection even further requires putting protection capabilities into the hands of individual programmers, so that protection policies can be implemented on the application level, i.e.

to protect resources in ways that are known to the specific applications but not to the more general operating system. Compiler-Based Enforcement.

OS-9 is modular, allowing new devices to be added to the system simply by writing new device drivers, or if a similar device already exists, by simply creating a new device descriptor.

All I/O devices can be treated as files, which unifies the I/O system. In addition, the kernel and all user programs are ROMable. The main body of the book assumes you have had a full course in logic design. I do NOT make that strong an assumption. I just assume you had We will start with appendix B, which is a logic design review.

However since is a prerequisite, we will go rather quickly over some parts. Many of the figures in these notes are based on figures. The impact of the VAX on the world had a lot to do with the fact that it was bulletproof. It was robust. It really worked as advertised. That was Dave’s work.” While Cutler’s operating systems work on the PDP 11 and VAX are legendary, Bell is quick to add that the dynamic range of Cutler’s work at DEC is often overlooked.

Device drivers literally drive everything you're interested in--disks, monitors, keyboards, modems--everything outside the computer chip and memory. And writing device drivers is one of the few areas of programming for the Linux operating system that calls for 9/10().

Performance is potentially limited in a tightly coupled system by a number of factors. These include various system components such as the memory bandwidth, CPU-to-CPU communication bandwidth, the memory available on the system, the I/O bandwidth, and the common bus bandwidth.

Parallel processing advantages of shared memory systems are these. There are a large number of software tools or software applications that have been specifically developed for the field sometimes referred to as molecular microscopy or cryo-electron microscopy or cryoEM.

Several special issues of the Journal of Structural Biology (see references below) have been specifically devoted to descriptions of these applications and several web. The CPU supported the standard PDP-8 negibus, but I/O bandwidth was 1/5 that of the PDP Thus, most, but not all PDP-8 peripherals could be used.

A few DEC peripherals such as the DF32 came with special options such as interleaving to slow them down for compatability with the PDP-8/S with a DB8S. Linux Device Drivers by Alessandro Rubini,available at Book Depository with free delivery worldwide.

These units incorporate their own processors, and operate in parallel with a local Unix host processor. All networks are connected to the network controller unit, which performs all protocol processing up through the NFS by: Security attributes of objects are described by security descriptors, which include the ID of the owner, group ownership for POSIX subsystems only, a discretionary access-control list describing exactly what permissions each user or group on the system has for this particular object, and auditing control information.
