The National High-performance computing academic annual meeting was founded in 2005 and has been successfully held for 13 years. The conference attracted nearly 2017 participants and 40 research institutes and manufacturers participated in the Conference. Each annual meeting will focus on the research progress and development trend of high-performance computing technology, major applications of high-performance computing, and other topics. It will provide scholars in related fields with a platfo
If we compare a PC to an ordinary person, an HPC System or supercomputer can be called a "Superman", because even an ordinary HPC System, its computing power is also several thousand times that of the PC. Top-level HPC systems, such as the Popular IBM Blue Gene series in Europe and America, another example is domestic "sugon", "inspur", "Lenovo", or "shenwei". It
Windows HPC Server 2008 is the successor to the existing Windows Computer Cluster Server 2003 (WCCS2003), based on the Windows Server 2008 64-bit system core. It provides new high-speed networks, efficient and flexible cluster management tools, service-oriented Architecture (SOA) engineering scheduling, support for partner cluster file systems, and can be used in large-scale parallel projects such as computational fluid dynamics, hydro-junction simula

Processor cores with custom extensions and shared memory the external HPC architecture of the internet is rapidly being replaced by an on-demand cluster, these clusters take advantage of off-the-shelf general-purpose vector collaboration processors, converged Ethernet (each link-gbit/s or higher speed), and multicore headless (headless) servers. These new on-demand
Now Linux clusters have become very popular in many fields. With the emergence of cluster technology and the increasingly adoption of open source software, it is now possible to build a supercomputer at a very small cost of traditional high-performance machines.
These two series of articles briefly introduce the concept of high-performance computing HPC using Linux cluster technology, and demonstrate how to build clusters and write parallel programs.

3.1 concept of Job Scheduling System
A cluster is the top-level unit of Windows HPC Server 2008 R2. A cluster contains the following elements.
Node: a single physical or logical computer with one or more processors. A node can be a header node, a computing node, or a WCF broker node.
Queue: an element that provides queuing and Job Scheduling functions. Each windows HPC
First, I copied an introduction and did not translate it.
The software capture-HPC (https://projects.honeynet.org/capture-hpc) is a client-side Honeypot, heavily based on the functionality of VMware.
A client software is installed on a virtual VMware Guest System (Windows XP) and a server side part of the software contacts the client by using a VMware proprietary protocol and instructs it to open a URL that
In job management, you can monitor and manage jobs that are submitted to a cluster. In the job list, each row is a job, and each column displays the job properties, job status, and indicator values. The job list provides a starting point for drilling down to job details and performing operations on one or more jobs.
The HPC Cluster Administrator provides several charts and reports to track job statistics for the cluster.

Test Time: answer the following question: Which of the following operating systems is the most efficient and reliable high-end computing system in your enterprise? 1) Linux, 2) solaris, 3) OpenVMS or 4) Windows?
Okay. The answer is over. If your answer is Linux, you get a very high score. If you select Solaris, you get 9 points. If you select OpenVMS, you get 8 points. If you choose Windows, after hearing what everyone said, "Are you sure your PC is powered on?" See.

Before this article, I suggest reading this article first: Linux High Performance Computing cluster –beowulf cluster One, may encounter problems in building a cluster
1. Cluster design/Layout of a major difficulty is the network, each family has a strategy, generally around the Beowulf variant.2. The deployment of the software lacks practical debugging, and it cannot be concluded that such deployment is successful and superior.3. Manual/Automated deployment of the entire process of operating sys
A Windows HPC Server 2008 Cluster Job is a request to a resource on a cluster and is the payload of the task to run on those resources. Cluster jobs can be simple, with only one task or many tasks to cover. The most common types of jobs are MPI jobs, parameter cleanup jobs, and task flow jobs.
To create a job, you define a set of properties that determine how the job will run. The job template for the job will provide default values for any job attri
