1. The document discusses Java generics and how they can be used to create type-safe generic methods and data structures.
2. It provides an example showing that without generics, N data structures and M algorithms would require NM methods, but with generics only N+M methods are needed.
3. The document covers generic syntax in Java using angle brackets <>, wildcards ?, and extends and super keywords to specify upper and lower type bounds for generic parameters. It includes code examples and quiz questions to illustrate generics concepts.

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.

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.
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.
Developing Distributed High-performance Computing Capabilities of an Open Sci...Globus
COVID-19 had an unprecedented impact on scientific collaboration. The pandemic and its broad response from the scientific community has forged new relationships among public health practitioners, mathematical modelers, and scientific computing specialists, while revealing critical gaps in exploiting advanced computing systems to support urgent decision making. Informed by our team’s work in applying high-performance computing in support of public health decision makers during the COVID-19 pandemic, we present how Globus technologies are enabling the development of an open science platform for robust epidemic analysis, with the goal of collaborative, secure, distributed, on-demand, and fast time-to-solution analyses to support public health.
2. 2
Create...
a box interface
− You can put into the box
− You can take out of box
− NOTE: needs to be able to handle ALL
possible types (not just primitives!)
GO!
3. 3
Generic Programing
generic programming is a style of
computer programming
written in terms of to-be-specified-later
instantiated when needed for specific
types provided as parameters
4. 4
Ex1
Given N data structures
Given M algorithms
If we want an algo for every data struct we
wind up with NM methods
− NOTE: this is BAD
Using generics we end up with only N+M
methods
− NODE: this is GOOD
6. 6
What are they for?
"a type or method to operate on objects of
various types while providing compile-time type
safety." (Java Programming Language)
Basically...
− IT MAKES LIFE BETTER!!!
7. 7
QUIZ!
If my program has 3 types of data
structures and 5 types of algorithms...
1)How many methods will there be with NO
generics?
2)How many methods will there be WITH
generics?
GO!
8. 8
The Syntax
ObjectName <Type Variable>
Ex2
− ArrayList<String> L=new ArrayList<String>();
Attention Test
− Create a method signature for the put
operation for a box, and it takes a
generic of some kind
GO!
9. 9
Lo Pi Hi
Lets take it up a notch!
Ok so there is a catch, if I say <Number>
− Integer, Float, ect.
It will not work!!!
Why you ask?
Attention Test
QUIZ!
10. 10
Quiz
How do you implement a method with
generic type that accepts all subtypes of
Number?
11. 11
Now that I have you attention
The fancy word for this is “variance”
But so you can see the big picture
Covariant: converting from a specialized
type (Cats) to a more general type
(Animals): Every cat is an animal.
Contravariant: converting from a general
type (Shapes) to a more specialized type
(Rectangles): Is this shape a rectangle?
Invariant: not able to convert.
12. 12
So how to make this work...
Using the Java wild card “?”
− Yes it is the
The basic idea is this
− < ? extends T >
− < ? super T >
Extends means all subtypes of T
Super means all super types of T
