Dear taki Users, dear colleagues, dear students,

I am writing as chair of the governance committee and faculty-lead for the user support in HPCF.

First of all, I am glad that you are all users of our system! We hope that it is useful to you and enables you to conduct more research.

Then as general reminders:

- For all, please send me citations for papers and theses (undergrad, Master's, PhD)! This is for our HPCF Publications webpage and our most important documentation of the success of HPCF.

- For PIs, you might want to review the users who have access to your group's data. These are the users in your Unix group. You can see the usernames of all from the output of the "getent group" command; to see your own group's users only, pipe the output into the grep command.  For instance, for me with username gobbert, my group is pi_gobbert, so I issue the command

getent group | grep pi_gobbert

to see all users who are in my Unix group. The point is that some of your students may have graduated or some previous collaborators are not active any more.

- For PIs, if you could, review which projects we list for your group.  Maybe you have new/additional ones (or maybe we failed to post ones that you submitted). Just send me the title, abstract, and people involved.

Finally, the real point of this message is that I am offering to meet with all interested in an online user meeting. Rough agenda:

1. Welcome, thank-you, introductions of HPCF staff and all attendees.

2. Review of the HPCF webpage, in particular, of the systems available.

3. Overview of ongoing projects to improve documentation (Matlab, R).

4. Collection of technical questions and comments on the existing systems.

5. Collection of suggestions for the future.

6. If needed, meeting of PIs only.

The meeting will be in one week, the Friday before the start of the spring 2022 semester, that is, Friday 01/28/2022, 11:00-12:00, online in my personal room at https://umbc.webex.com/meet/gobbert

Thank you all,

Matthias Gobbert, Math & Stat, gobbert@umbc.edu,

chair, HPCF Governance Committee

The older versions of Matlab are also still available in case you need to use them. You can see the versions of Matlab we currently have installed on Taki with this command:

module spider MATLAB

Dear Researchers, Colleagues, and Students,

Technical staff from NVIDIA will give us a 30 minute intro call to go over their new product releases and see how NVIDIA might be able to help us escalate our AI initiatives and speak to our current use cases and projects.

This is this Wednesday, 10/13/2021, 01:00 p.m. at the conference line 703-871-85

02 (passcode/roomcode 3761).

If you cannot make it, but would like me to send you a copy of the notes that I intend to take, please drop me a note in conventional e-mail.

Even if you intend to attend synchronously, you may want to send me questions beforehand, so I can share them with NVIDIA by e-mail for preparation. For instance, what applications do you use or wish to use on GPUs? What programming language (CUDA or OpenCL?)? What is limiting you from accomplishing more?

Matthias Gobbert, Mathematics and Statistics, gobbert@umbc.edu

(Chair of the HPCF Governance Committee)

To all taki users,

Our work bringing the taki cluster environment up-to-date has concluded. Please begin normal use of the cluster environment.

Please let us know if you have any questions or concerns by submitting a descriptive help request form found at the following link.

HPC System Administrator

To all taki users,

On Tuesday October 5, 2021 the taki cluster environment will be down and inaccessible from 5pm - 9pm EDT. 

Once our work is done on Tuesday, we will make another announcement.

As always, let us know if you have any questions or concerns by submitting a descriptive help request form found at the following link.

HPC System Administrator

To all taki users,

At 12:30PM portions of the taki cluster environment became unavailable.

The management system attempted to correct the issue by selectively killing administrative processes until, at 12:56PM, the entire system became unresponsive.

After reseting the management system and ensuring various processes restarted appropriately, we were able to bring the system back online at around 2PM.

While no compute hardware was rebooted, this unscheduled downtime likely resulted in some loss of state on running jobs. Please inspect the output of any jobs that completed during this time for obvious errors or rerun them.

If you have experienced any other issues during this time---or have any other questions, comments, or concerns---please submit a descriptive help request via the form found at the following link.
