Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?
We describe the deployment and use of Globus Compute for remote computation. This content is aimed at researchers who wish to compute on remote resources using a unified programming interface, as well as system administrators who will deploy and operate Globus Compute services on their research computing infrastructure.

Graspan: A Big Data System for Big Code AnalysisAftab Hussain
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.

1. Session on Openstack
In this session, we will see , how to use openstack to operate your own private
cloud :
By the end of the session, you will have a core understanding of what OpenStack is
and you will know the basics of setting up and administering OpenStack. You will
also understand some commonly used OpenStack services.
What is OpenStack?
OpenStack is an open source cloud computing platform that is used by organizations
to manage and control large scale deployments of virtual machines, such as in a
cloud computing or virtual private server environment. OpenStack is a popular
choice for organizations because it is scalable, reliable, and provides a high degree
of control over the underlying infrastructure.
Besides being used to manage deployments of virtual machines, OpenStack can also
be used to manage storage and networking resources in a cloud environment.
In some ways OpenStack can be compared to AWS but here are some
key differences between the two:
• OpenStack is an open source platform, while AWS is a proprietary platform.
• OpenStack offers more flexibility and customization options than AWS.
• OpenStack typically requires more technical expertise to set up and manage than AWS since you
basically have to set up everything yourself.
Let's go into more details about what OpenStack offers.
Openstack Components
• OpenStack is a free and open-source cloud computing software platform designed to provide
IaaS •
• OpenStack software includes components to allocate/manage CPUs, IPs, Ports, Subnets, Storage etc.
2. Beyond standard infrastructure-as-a-service functionality, additional components provide
orchestration, fault & service management, and other services to ensure high availability of user
applications.

Getting Started with OpenStack Horizon
Horizon is the name of the default OpenStack dashboard, which provides a
web based user interface to OpenStack services. It allows a user to manage the
cloud.
To access your new cloud's OpenStack dashboard (called Horizon) you will need
to obtain Horizon's administrator password. The username is "admin".
To access password : login on control node and open file
File to get admin password : cat /etc/kolla/admin-openrc.sh
Login using "admin" and the password you just accessed.
7. Create a Project in OpenStack Horizon
In OpenStack, the cloud is divided through the use of projects. Projects have
associated with them users, who have differing levels of access, defined by
roles. An administrator defines resource limits per project by modifying
quotas.
Now we'll learn how to create a project and associate a user with it. And we
will learn how project quotas can be adjusted.
There are three root-level tabs on the left menu in Horizon: Project, Admin,
and Identity. Only users with administrative privileges can see the admin tab.
To create your first project, navigate to Identity -> Projects.
Several projects already exist, including the admin project. These projects are
deployed by default and generally should not be modified.
Click the Create Project button near the top right to create a new project.
8. Under the Name field, specify a name for the project. This example project is
called Demo-project. You can also add Project Members and Project Groups
but we are not going to cover those yet. Click Create Project to finish creating
the first project.
Once created, the project appears in the Project Listing page.
While in the project listing page, you can view and adjust quotas for this project
as the admin user. Quotas are limits on resources, like the number of instances.
To view the quotas for this project while in Identity -> Projects tab, find the
drop down to the right with the first option being Manage Members. From this
menu, click Modify Quotas to view the default quota values.
How to Create a User and Associate with Project
9. Now that you have a project, you can associate a user with it. There is already
the default admin user but now let's see how to create a new user and login
with the new user.
First navigate as admin to Identity -> Users. By default, there are several users
already listed, and this is expected. These are created during cloud deployment
and should generally not be modified.
Click the Create User button.
On the Create User form set values for User Name, Password, Primary Project,
and Role. The Email field is optional but is helpful for password resets. For the
Project choose the project we created earlier.
For Role there are several options depending on the level of access required.
The default OpenStack roles are reader, member, and admin. Additional roles
also exist in the drop down. Reader is the least authoritative role in the
hierarchy. For this example, choose member for the role.
Press Create User to create the user.
Next, log out of Horizon as admin, and log back in with your new user. Upon
logging back in you are by default in the newly created project. You can see the
project you are currently in at the top left and your user can be seen at the top
right of Horizon.
10. Managing and Creating Images
Now let's see how to upload an image (not a graphical image but a copy of a
Linux installation) into OpenStack as well as create images out of an existing
instance.
Images contain a bootable operating system that is used to create instances.
We will learn how to upload images to Glance through Horizon and how to
create an image from an instance snapshot. Glance is tool for managing images
that allows users to discover, retrieve, and register VM (virtual machine)
images and container images. Glance uses Ceph to store images instead of the
local file system.
To access images from within your Horizon Dashboard, navigate to the Projects
tab. Within the projects tab, select Compute and then select Images. This tab
contains a list of all your images within OpenStack.

11. Images can be uploaded through your Horizon dashboard by clicking the
Create Image button. When creating an image you must choose the Format
of the image. With our configuration, the recommended format for images is
QCOW2 . QCOW2 is the most common format for Linux KVM, expands
dynamically, and supports copy on write.
In order to upload an image on Horizon, you must first have the image locally
on your machine. In this example, we will upload a CirrOS image. You can
download a CirrOS image here.
Now click the Create Image button near the top right.
Create an Instance in OpenStack Horizon
With OpenStack, instances, or virtual machines, play a large role in a cloud's
workload. OpenStack provides a way to create and manage instances with its
compute service, called Nova.
12. Nova is the OpenStack project that provides a way to provision compute
instances. Nova supports creating virtual machines, baremetal servers, and has
limited support for system containers. Nova runs as a set of daemons on top of
existing Linux servers to provide that service.
Now let's learn how to create an instance, including setting up a private
network and router, creating a security group, and how to add an SSH key pair.
Create a Private Network
First, let's learn how to create a private network and router. Later we will
create an instance on this private network. The router is created so the private
network can be connected to your cloud's public network, allowing you to
assign a floating IP address to it, making the instance accessible over the
Internet.
To create a private network, begin by navigating to Project -> Network ->
Networks. Then click Create Network.
For this example, we'll create a network with the following details:
• Network Name: Set a name for the network. This example is called
Private.
• Enable Admin State: Leave this checked to enable the network.
• Create Subnet: Leave this checked to create a subnet.
• Availability Zone Hints: Leave this option as default.
Next, move on to the Subnet tab of this form and use these details:
• Subnet Name: Set a name for the subnet. This example subnet is called
private-subnet.
13. • Network Address: Select a private network range. For
example: 192.168.0.1/24
• IP Version: Leave this as IPv4.
Gateway IP: This is optional. If unset, a gateway IP is selected automatically.
Create a Router
You next need to create a router to bridge the connection between the private
network and the public network. The public network is called External.
To create a router, begin by navigating to Project -> Network -> Routers.
Click Create Router.
14. Input this data for this example:
• Router Name: Set a name for the router here. This example router is
called Router.
• Enable Admin State: Leave this checked to enable the router.
• External Network: Choose the network External/publicl.
• Availability Zone Hints: Leave this as the default.
Once complete, create the router by pressing Create Router.
Connect Router to Private Network
Next, connect the router to the private network by attaching an interface.
Performing this step allows network communication between the Private and
External networks.
To attach an interface to the router, first navigate to the list of routers and
locate the one previously created.
Click the name of the router to access its details page. This is where the
interface is attached. There are three tabs: Overview, Interfaces, and Static
Routes. To attach an interface, navigate to the Interfaces tab then load the
form to attach an interface by clicking Add Interface near the top right.
15. You can visually see the network topology for your cloud by navigating
to Project -> Network -> Network Topology.
The example above indicates the External network is connected to the Private
network through the router called Router.
Security Groups
Security groups allow control of network traffic to and from instances. For
example, port 22 can be opened for SSH for a single IP or a range of IPs.
Let's see how to create a security group for SSH access. Later we'll apply the
security group we create to an instance.
To view and manage security groups, navigate to Project -> Network ->
Security Groups.
17. Create an Instance
We now have almost everything in place to create an instance.
To create an instance, begin by navigating to Project -> Compute -> Instances.
Then click the Launch Instance button.
On the details tab, fill in the following details:
Instance Name: Set a name for the instance. This example instance is
called demo-vml.
Description: Optional. Set a description if this applies.
Availability Zone: Leave as the default, which is nova.
• Count: Controls the number of instances spawned. Just create 1.
Next, move to the Source tab allowing you to specify an operating system
image.
18. This concludes configuring the instance's source. Next, move to the Flavor tab.
Flavors are a way to define the VCPUs, RAM, and Disk space used by an
instance. Pre-built flavors are available for you. For this step, select an
appropriate flavor from the options under the Available heading. This example
uses the m1.small flavor. Click the up arrow to move it to the Allocated
section.
19. Next, move to the Networks tab.

Network tab.
In this section, you specify the network with which the instance is associated.
For this example, select the Private network created previously. You can
choose the External network as well, but this is generally recommended
against in favor of using a floating IP should your instance require Internet
connectivity.
You should only expose portions of your network as necessary. This reduces the
attack surface and improves application security. If a private network is not
created and an instance is created in a default cloud, it is associated with the
External network. This means the instance consumes a public IP and it could be
reached over the Internet.
Next, skip over the Network Ports tab and move to the Security Groups.
20. As the final step, move to the Key Pair tab.
In this section, you specify an SSH public key to inject into the instance. You
can upload your key at this stage using this form using the Import Key Pair
button. You can also create a key pair on this tab.
In this section, you specify an SSH public key to inject into the instance. You
can upload your key at this stage using this form using the Import Key Pair
button. You can also create a key pair on this tab.
We will create a key pair from the control node in our cloud so this instance
will be accessible over SSH from that node.
To create the SSH key pair from the first hardware node, the first step is to
login to the first hardware node.
After logging in to the node, use ssh-keygen to generate an SSH key pair
The private key is saved in the default location of /root/.ssh/id_rsa and a
passphrase is set for additional security.
To view the contents of the public key, use cat /root/.ssh/id_rsa.pub.
For ex.
21. [root@ubuntu ~]# cat /root/.ssh/id_rsa.pub
ssh-rsa

Copy the entire key. It starts with "ssh-rsa" and continues all the way until the
end.
Now back to the Key Pair tab. Click Import Key Pair.
Input the following values:
• Key Pair Name: Set a name for the SSH public key. This example public key is
called demo-key but it can really be anything you like.
• Key Type: This example uses an SSH Key key type.
• Public Key: Paste in the public key you just copied.
Click Import Key Pair.
Once the public key is imported, create the instance by pressing Launch
Instance.
22. The instance goes through a build process. Allow a few minutes for this to
occur. When complete, the instance appears in the Instances Listing page.
Assign and Attach Floating IP
The instance created previously is associated with a private network. Presently,
the only way to access this instance is to connect to it from with the cloud's
hardware nodes. Another option for connecting is to use a floating IP. In this
section, we demonstrate how to allocate a floating IP and attach it to this
instance.
To allocate a floating IP, first navigate to Project -> Network -> Floating IPs.
Then click Allocate IP to Project.
In the popup, make sure Pool is set to External (and optionally add a
description) and then click Allocate IP to add this floating IP address for use.
Click Associate. This instance is now accessible over SSH from the first
hardware node of your cloud.
