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.
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.

Globus Compute wth IRI Workflows - GlobusWorld 2024Globus
As part of the DOE Integrated Research Infrastructure (IRI) program, NERSC at Lawrence Berkeley National Lab and ALCF at Argonne National Lab are working closely with General Atomics on accelerating the computing requirements of the DIII-D experiment. As part of the work the team is investigating ways to speedup the time to solution for many different parts of the DIII-D workflow including how they run jobs on HPC systems. One of these routes is looking at Globus Compute as a way to replace the current method for managing tasks and we describe a brief proof of concept showing how Globus Compute could help to schedule jobs and be a tool to connect compute at different facilities.
How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

2. Linux Kernel Organization
• Linux supports numerous architectures this
means that it can be run on many types of
processors, which include alpha, arm, i386,
ia64, ppc, ppc64, and s390x.
• Most of the source code is written in C and is
hardware independent
• A portion of the code is heavily hardware
dependent and is written in a mix of C and
assembly for the particular architecture.
• The heavily machine-dependent portion is
wrapped by a long list of system calls that serve
as an interface.
Embedded Linux Course
10. Bootstrap Loader
• Not to be confused with a bootloader, many
architectures use a bootstrap loader (or second-stage
loader) to load the Linux kernel image into
memory.
• Some bootstrap loaders perform checksum
verification of the kernel image, and most
perform decompression and relocation of the
kernel image.
• The bootloader controls the board upon power-up
and does not rely on the Linux kernel in any
way
Embedded Linux Course
11. Bootstrap Loader (cont.)
• In contrast, the bootstrap loader's primary
purpose in life is to act as the glue between a
board-level bootloader and the Linux kernel
• It is the bootstrap loader's responsibility to
provide a proper context for the kernel to run in,
as well as perform the necessary steps to
decompress and relocate the kernel binary
image
• It is similar to the concept of a primary and
secondary loader found in the PC architecture.

14. Kernel Entry Point: head.o
• arch/<ARCH>/kernel/head.S
• The head.o module performs architecture- and
often CPU-specific initialization in preparation for
the main body of the kernel. CPU-specific tasks
are kept as generic as possible across
processor families
• Machine-specific initialization is performed
elsewhere
Embedded Linux Course
15. head.o performs the following tasks
• Checks for valid processor and architecture
• Creates initial page table entries
• Enables the processor's memory management
unit (MMU)
• Establishes limited error detection and reporting
• Jumps to the start of the kernel proper, main.c
Embedded Linux Course
16. Kernel Startup: main.c
• Every architecture's head.o module has a similar
construct for passing control to the kernel
proper.
– b start_kernel
• start_kernel() located in .../init/main.c.
• main.c does all the startup work for the Linux
kernel, from initializing the first kernel thread all
the way to mounting a root file system and
executing the very first user space Linux
application program.
Embedded Linux Course
17. Further Study
• See the architecture-dependent portions of the
linux source code, for example, system
initialization and bootstrapping, exception vector
handling, address translation, and device I/O.
• Cross-Referencing Linux
– http://lxr.linux.no
To create a device driver, the programmer must have a
register-leve specification for a given piece of hardware
