What is high performance computing (HPC) and what can it do for me? How can ACENET help? Used by researchers across many disciplines to tackle analyses too large or complex for a desktop, or to achieve improved efficiency over a desktop, this session takes participants through the preliminary stages of learning about HPC and computing clusters, and how to get started with this type of computing. It then reviews software packages available for applications, data analysis, software development and compiling code. Finally, participants will be introduced to the concept of parallel computing to achieve much faster results in analysis. This session is designed for those with no prior experience in HPC, and are looking for an introduction and overview. (1 hour) (Slides) (Video)

Linux is the terminal interface used to enable you to use the ACENET and Compute Canada HPC clusters from your desktop. It’s the tool to get your data on the clusters, run your programs, and get your data back. In this session, learn how to get started with Linux, how to create and navigate directories for your data, load files, manage your storage, run programs on the computing clusters, and set file permissions. This workshop is designed for those with no prior experience in working with a terminal interface. Participants are encouraged to bring a laptop. (1 hour) (Slides) (Video)

Data analysis and processing has been around for a long time – what is new is the variety, volume, and velocity at which things can now be quantified. Today, data is available form a myriad of sources such as, tweets, GPS coordinates, images, and videos from mobile devices, and massive on-line archives of digitized manuscripts to name a few. The amount and variety of data make it difficult to analyze and we as a society are still working out the best ways to use this data to improve our understanding and make better decisions. This seminar will appeal to people from humanities to natural sciences and in-between, and will help you determine how your data fits into the big data ecosystem and introduce some tools to help you manage and analyze your data. (1 hour)

This session provides an introduction to the Compute Canada cloud which is used to create and manage virtual machines.

Learn how to create a virtual machine and how to start using it. (1 hour) (Slides)

Version control has been a key concept in software engineering for decades, but it’s now becoming known and used by more than just hard-core programmers. The most popular tool is currently Git, but it’s part of a large “ecosystem” of web services (GitHub, BitBucket, GitLab, …) and competing tools (Subversion, Mercurial, Perforce…). What do these all mean? How do you choose a combination of version control tools and services for your work? (1 hour) (Slides)

Data Carpentry trains researchers in the core data skills for efficient, shareable, and reproducible research practices covering the full lifecycle of data-driven research. Through a two-day hands-on approach, the focus is on the introductory computational skills needed for data management and analysis. The workshops are domain-specific, and include life and physical sciences, and humanities and social sciences. Sessions build on the existing knowledge of participants to enable them to quickly apply the skills learned to their own research. This workshop is of interest to: current researchers and their teams using large data sets; anyone considering a research project that involves large data sets; or students who want to gain these skills to enhance their career choices. A laptop is required. (2 days)

This workshop provides a brief overview of Research Data Management, with a focus on the development of Data Management Plans (DMPs). DMPs are a key component of the data management process that touch on all aspects of RDM, describing how data are collected, formatted, preserved, and shared. Importantly, DMPs also promote the consideration of the costs and challenges associated with managing research data. Participants will learn about RDM in the context of the research data lifecycle, gain an understanding of the basic components of a DMP, create a DMP for their research project using the Portage Network’s DMP Assistant tool, and think critically about data management challenges and how to evaluate DMPs. No software or prior data management training required. Before the workshop, participants should create an account on the Portage Network DMP Assistant tool and come prepared with information about a specific project for which the DMP can be written (e.g., a project workplan or research abstract). Participants must also bring their own laptop. (1.5 hours)
