HPC Pack install guide

HPC Pack install guide : Science,Server & Web : (c)Rupert S


****

The point of this document is to make installing and managing HPC High Performance Computation possible,

To be clear A person or organisation that wishes to have high performance cloud nodes with docker..
Have the capacity to install Microsoft HPC pack & Docker, The configuration settings are at the top,
In the lower half are the docker VM's you can potentially use to University,Gamer & Corporate advantage.

Clearly the bat files make install easier than running individual commands one by one..
Both the bat files and the commands are in the document,
The work in this document took months & hereby is offered to the research community.

Firstly HPC pack should be installed on windows; However the docker configuration works on Linux..
However you have to first install Docker on for example Ubuntu,

Of-course the main server for Microsoft HPC pack needs to be windows (Preferably Server 2008/2016/2018),

Nodes can be Windows 7 to 10 & Server 2008 to 2018 & Linux (Mainly REDHAT,CentOS,Ubuntu,SuSE)

Personally CentOS rocks for servers, Ubuntu has professional server configurations & lots of options,RedHAT is the main line of secure server that registers all security & tests all.

In my experience RedHAT offers large corporation support; As do Ubuntu & CentOS & Obviously Microsoft offers full confidence.

Node configuration guidelines:

Head node,Workstation/Server

Nodes (potentially 2+)

Cloud nodes (potentially limitless)

Example Plans : 

Include every 8 to 256 core Compute node (Win Serve 2 Win 10) into the : Cfana Ridge Connect(tm)

Global Compute Network: Operational & functional: For every HPC Workstation 8 Core to 256 Core, 4gb RAM to 4Tb RAM

Windows server: Step 1


install Microsoft HPC Pack - Microsoft HPC Pack server/Workstation/Unmanaged server/node

Head Node
127.0.0.1,dn.n-helix.com,node.ns4v.icu,worldcommunitygrid.org,lhcathome.cern.ch,cern.ch,boinc.bakerlab.org,cloudflareworkers.com,cloudflare.com,cloud.sfr.fr,sfrcloud.sfr.fr,webrlb01.cern.ch,boincai01.cern.ch,8.8.4.4,1.1.1.1

You will need a server certificate such as a comodo or digicert or microsoft.. for the next page of hpc pack install,
A node address such as https://www.dynu.com for the node

https://www.gogetssl.com/compare-domain-sslcertificates/

Docker though the install service

powershell Install-PackageProvider -Name NuGet -Force
powershell Install-Module -Name DockerMsftProvider -Repository PSGallery -Force
powershell Install-Package -Name docker -ProviderName DockerMsftProvider -Force

or run one of these instead of step 1 & 2:

For Nvidia GPU : https://is.gd/DockerNvidiaServerInstall
For AMD GPU : https://is.gd/DockerAMDServerInstall

Windows 7/8/10: Step 1


install Microsoft HPC Pack node or workstation/server

The initial detection system would launch for Container VM & also pull user data into the VM (the necessary ID from project add device & also set the VM and OS use for special case use and non generic project data,
Of special note is the use of Linux containers; This container potentially could batch multiple projects with finesse; In particular Science Linux and Alpine (for size and usability) (science kernel version is possible)

Some ambitious specs for a VM

8 cores, 8Gb ram, 1 GPU (2gb ram), 20GB HDD per process ^^

That being said : Hyper V VM allows Dynamic ram as an option & this means the ram can be used by the system if the VM is not using it..

Docker has a similar method in that the Docker VM uses a pre-defined space :
In my case 16gb and 8 cores, This is sub allocated along with linux swap ..
To processes in containers, Containers can use most varieties of linux including alpine (very small memory footprint) Alpine is suitable for science projects as is the Docker Kernel.
