Parallel Algorithms for Calculating Underground Water Quality

The PVM system helps us in designing parallel processing programs for multi-computer systems. The implementation of the parallel algorithm enables the solving of large mechanic problems requiring large amounts of computer time and memory.

Figure 3. Xndd program

We designed and built the X Window System program Xndd under Linux. This program can be used for simulating the surface of underground water and the transfer and diffusion of pollution. The interface of the program and some calculation results are shown in Figure 3.

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
