by Advanced Research Computing 24 Nov '25

24 Nov '25

Dear Grex / HPC Users, Thank you all for using our HPC resources! Another year passed since our last call. This call is to apply for , or to renew the local resource allocations for the next, 2026 year. Please find the Local Resource Allocation Call 2026 forms and conditions attached! Thank you for your interest! Your HPC Team. ==== UManitoba HPC (Grex) resource allocation call 2025-2026 Overview of HPC compute and storage resources This call is for renewing and updating the allocation of resources on the Grex HPC system, specifically, CPU time (in Core Years, CY) and storage (in TBs). There is no charge for using Grex for University of Manitoba academic PIs. The request for resources must come from Faculty members (Principal Investigators, PIs), and the allocation is given to the PI’s research group, their group members, and academic external collaborators. Grex is the High-Performance Computing (HPC) system at the University of Manitoba. Since the SISF renewal completed in 2024, its generally available compute capacity is as follows: · 30 of 192-core AMD Genoa 9654 nodes with either 4 GB or 8 GB of memory per core. · 54 nodes of 40 or 52-core Intel CascadeLake CPUs, 3.5 ot 9GB of memory per core · 2 nodes with 4x NVIDIA V100 GPUs, Intel CascadeLake CPUs, and 192 GB memory · 2 nodes with 2x NVIDIA L40s GPUs, AMD Genoa CPUs, and 384 GB memory. The total number of allocatable CPU cores is 8,644. · General GPU nodes are available on a first-come, first-served basis. There are no dedicated GPU allocations, as the number of GPUs (eight V100s and four L40s) is limited. We ask you to indicate if you anticipate using the GPUs in your proposal. · Contributed resources: A significant number of contributed GPUs (34 total, comprising A30 and V100 models) and CPU cores (1,992 AMD Genoa) are available. These resources are owned by contributors and are not allocatable but can be used opportunistically when not in use by their owners, especially for short compute jobs. The Project storage, allocatable per research group, has a total capacity of 2 PB, with 1.7 PB designated for the contributing Faculties of Agriculture, Engineering, and Science. · The /project space is allocated by default between 5 and 40 TB per group. Up to 80TB can be allocated by PI’s from non-contributing Faculties, subject to the overall capacity. · Larger allocations are possible through this call for research groups from contributing Faculties. Research groups from these Faculties will be given priority for/project storage according to their contributions. Categories of Resource Requests There are two categories of resource requests: · Default allocations or “Rapid Access Service” (RAS) is limited to under 60 core-years, 4 GB memory per core, and 5 to 40 TB of Project storage per research group. RAS requests do not require a full proposal. For information and access, please email arc(a)umanitoba.ca . · Resource Allocation Call (RAC): Users who need more core-years or storage than the RAS limits provided above, should request resources via a RAC proposal during this call. Proposals must be submitted in the format described below. Often, RAC proposals are recurring, as research projects may span more than one year. PIs of recurring projects can resubmit the same proposal as last years’, however, in this case we ask applicants to update progress/publication records and review/update the value of requested resources, especially storage. Proposal Format and Submission Timelines Please use the attached 2026 RAC Request Template for your proposal. You may remove all explanations (text in italics) if desired. The Template is intended as a guide. Expected lengths for each section are included in the template, but your proposal may use more or less space, depending on the size and complexity of the request. Proposals for the use of Grex resources will be reviewed by the Advanced Research Computing (ARC) Committee and Grex technical staff to ensure resources are used efficiently. Based on total available Grex resources and the total volume of all the requests received, the allocations may be scaled to fit within the system’s capacity.

Use our training portal to discover what ACENET training is coming up, register and participate in sessions, and access course materials. You can view our full catalogue of offerings on our website. Introduction to Cloud 28 October, 1300-1600hrs Atlantic / 1330-1630hrs NL Cloud computing provides great flexibility allowing complete control of the computing environment. In addition, the environment can be copied, backed up, created and recreated in automated ways. This workshop will start you on the path towards making use of the great flexibility and power of cloud computing. In this workshop we will cover what a cloud is and basic cloud concepts such as virtualization, networking, and security. We will create our first virtual machine in the the national Openstack cloud and perform some essential Linux administrative tasks. This is a beginner level workshop, but participants should have taken The Carpentries Unix Shell, Introduction to Linux, or have the equivalent experience. Static Websites in the Cloud 30 October, 1300-1600hrs Atlantic / 1330-1630hrs NL A common use case for cloud computing is web hosting. We will discuss differences between static and dynamic websites, with a focus on the security and maintenance benefits of static websites. We will make use of pre-created virtual machines to create a website using the Jekyll static website generator, and along the way cover markdown a human readable syntax for formatting text. This is a beginner level workshop, but participants should have taken The Carpentries Unix Shell, Introduction to Linux, or have the equivalent experience. Desktops in the Cloud 4 November, 1300-1600hrs Atlantic / 1330-1630hrs NL The Cloud provides access to hardware resources beyond those available on your laptop or desktop, though you may still want to interact with that hardware as if it were your laptop using a graphical user interface (GUI) desktop. In this workshop we will install a GUI desktop on a remote virtual machine and connect to it from our laptop, allowing us to use this remote desktop almost as if it were our local machine. This is a beginner level workshop, but participants should have taken The Carpentries Unix Shell, Introduction to Linux, or have the equivalent experience. Command the Cloud 6 November, 1300-1600hrs Atlantic / 1330-1630hrs NL In ‘Introduction to Cloud’, we used the OpenStack web interface to create our first virtual machine. With this web interface many common tasks can be performed, however, some important tasks cannot be completed using only the web interface; instead a command line interface (CLI) is needed. The CLI also allows access to some additional and very useful tasks, such as downloading virtual machine images, and provides access to information not shown in the web interface. In this workshop, we will show how to setup and use the OpenStack CLI and perform some common tasks when managing virtual machines. This workshop is an intermediate level, and participants should have taken Introduction to Cloud, or have similar experience in creating virtual machines in an OpenStack cloud. Using Git Tools Part I: Version Control 20 November, 1300-1630hrs Atlantic / 1330-1700hrs NL Version control is the practice of managing and sharing changes to documents, programming code, websites or any other files to keep track of what’s been changed, by whom, when and why. All previous versions of files are saved and you can even revert to a previous version. Git is a version control software. Git-portal sites, like GitHub or GitLab, offer many useful features to facilitate collaborative development. This is the first workshop of a two-part series. The first session focuses on version control. The second explores using Git for collaborative development. This beginner level session introduces you to Git. We show you how to create a repository, record changes to files, explore and restore from the recorded history and how to resolve conflicts (when one member overwrites another’s changes). This is a beginner level workshop, but participants should have taken Introduction to Linux and the Unix Shell, or have equivalent experience. Using Git Tools Part II: Collaboration Platforms 27 November, 1300-1630hrs Atlantic / 1330-1700hrs NL This is the second workshop of a two-part series. The first session focuses on version control. This session focuses on collaborative development workflows using Git-collaboration sites like GitHub, GitLab or Bitbucket. It demonstrates how to work with branches, issue tracking, contribute to projects using pull-/merge-requests, code-review, how to run CI/CD-pipelines, and how to use other common features of these platforms. This is a beginner level workshop, but participants should be familiar with Version control using Git, either from Part 1 of the series, a Carpentries workshop, or equivalent experience.

Updates on the Multi Factor Authentication
by Grigory Shamov 09 Jan '24

09 Jan '24

Dear Grex/HPC User, As you might have heard, the University is switching from Duo to Microsoft Entra MFA solution. The Digital Research Alliance of Canada, and our UManitoba HPC system, Grex, continue Cisco Duo as the multifactor authentication (MFA) second factor. As of today (January 9, 2024) enrollment in Duo is required to access Grex, and optional but highly recommended to access the Alliance systems such as Cedar, Graham, and Narval. On Grex and Alliance systems, the following second factors are enabled: * Duo smartphone app (Android and iOS) * Yubico Yubikey cybersecurity USB key device * 10 one-time codes (recommended as a backup 2FA in addition to the primary device). The one-time codes require another 2nd factor registered first. Enrollment into the Alliance Duo is through CCDB: https://ccdb.alliancecan.ca<https://ccdb.alliancecan.ca/>. A successful Enrollment enables the MFA requirement on every SSH login on both Grex and Alliance systems like Cedar, Graham, Narval, or Niagara. The following Grex Documentation page explains the process of the device enrollment with screenshots: https://um-grex.github.io/grex-docs/connecting/mfa/ Our staff will be available for support in case you have difficulty enrolling or using MFA. If you have any questions, please let us know (by an email to support(a)tech.alliancecan.ca<mailto:support@tech.alliancecan.ca>, mentioning “Grex” in the subject line). Thank you for your attention to this message! -- Your Grex HPC team.
