Science Cloud

The Science Cloud is one of the main services that the CoARE project offers. Science Cloud provides cloud-based services to researchers and students by providing virtual machines (VM).

The Science Cloud can be utilize by students and researchers who have the following requirements:
  • website hosting
  • file backup;
  • cloud computing;
  • cloud database;
  • cloud-based email services; and
  • test and development.

Default Allocation

  • Cores: 2
  • RAM: 4 GB
  • Storage: 40 GB

How to Use (Linux OS)

  • Login
    Open the terminal and log-in in your cloud account through SSH:
     $ ssh [options] <username>@<hostname> 

    In accessing science cloud, one common option is -X since it allows users to view and run GUI based applications.
    Note: In case software execution takes too long, add the -C option in the ssh command to enable compression.
  • File Upload
    To upload files to cloud, use the scp command:
     $ scp -rv <file> <username>@>hostname>:<path to the directory 
  • Add Software
    To add software to cloud, you can either load pre-installed modules, transfer binaries from your local computer or download from the internet
    • To transfer binaries, use the scp command:
       $ scp -rv <path of the binary> <username>@>hostname>:<path to the directory> 
    • To load modules, issue the command:
       $ module load <package name>/<package version> 

      Note: To view the list of available modules, use either the whatis or avail option.
    • To download packages from the internet, issue the yum command since the cloud nodes were installed using CentOS:
       $ yum install <package name> 
  • File Download
    To download files from cloud, use the scp command in your local computer:
     $ scp -rv  <username>@>hostname>:<path of the file> <path to directory 

How to Use (Windows OS)

  • Login
    1. Open PuTTY application
      You can download the application on this website if you don't have it yet: http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe
    2. Set port number to 22, then insert IP address of the VM.
    3. Under SSH, select “Auth”. Then browse the location of your private key. Click “Open”



    4. When the terminal opens, enter the account user name. To allow GUI applications from your VM to run on local computer you need to have Xming and configure your PuTTY application before Logging-in.

  • Configure Xming
    1. Download and install Xming.
    2. Run application “XLaunch”
    3. Select default settings then save configuration.
    4. Click “Finish”.
  • Configure PuTTY
    1. Open PuTTy application.
    2. Configure as shown below:
      • 2. 1. Under Session, insert IP address of VM and set port number to 22.
      • 2. 2. Select Windows to set the size of window and control the scrollback in the window.



      • 2. 3. Under SSH, select “Auth”. Then browse the location of your private key. Click “Open”.



      • 2. 4. Under SSH, select X11 the check “Enable X11 forwarding



      • 2. 5. Select SSH and check enable compression. Enabling compression allows some applications to run faster.

  • Upload/ Download Files
    1. Download and install winscp.
    2. Setup the program.
    3. Establish connection to HPC cluster. Set port number to 22 and insert given IP address. Enter user name then click “Login”.
