To all taki users,

We were able to resolve the networking issue affecting the batch hardware partition. It is possible that running SLURM tasks on this partition were left in a bad state.

Dear Researchers, Colleagues, and Students,

This is my regular reminder, coming from the HPCF Governance Committee as well as from the PI/co-PIs of the NSF MRI grant that funded a lot of the nodes of HPCF, that you please send me citations for all publications that used HPCF resources!

We want to post them to the HPCF webpage, see hpcf.umbc.edu/publications, for NSF reporting, but even more importantly in some ways, we want to impress on the UMBC administration how vital HPCF is to so many researchers and students doing their research.

To this end, please also particularly send me information on student theses (senior/undergraduate, MS, PhD)! Feel free to go back a year in checking if we have the information. If in doubt, send again.

Also update previously reported submissions, if they have been accepted or appeared now. You can always search the publications page for your own name to see what information we have. Also let me know any mistakes we might have (typos, etc.)

To all taki users,

Both taki login nodes (taki-usr1.rs.umbc.edu and taki-usr2.rs.umbc.edu) are now available for use.

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

Roy Prouty

HPC System Administrator

We are aware of and currently investigating issues on taki-usr1.rs.umbc.edu. As we investigate and troubleshoot this system, please direct all logins to taki-usr2.rs.umbc.edu. I will send another announcement when taki-usr1.rs.umbc.edu is available for use again.

Thank you for your understanding here.

To all HPCF users,

Our work bringing the two HPCF cluster environments up-to-date has concluded. Please begin normal use of the clusters.

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

To all HPCF users,

On Tuesday April 12, 2022 both HPCF clusters (ada & taki) as well as the other compute systems that make use of HPCF Research Storage will be down and inaccessible from 5pm - 9pm ET. 

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.

HPCF System Administrator

All taki users,

We'd like to announce that all 2018 and 2021 hardware now has Sub-NUMA Clustering (SNC) enabled. You can read more about SNC at the link below.

Additionally, the Intel 2021b toolchain is now the default Intel toolchain module. Please be aware that this change will affect any user using the default module environment.

As always, please file a ticket at the link below if you have any questions or concerns.

Thanks!

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.

It was great to have people visit with me, the HPCF RAs Carlos Barajas and Dan Kelly, and the system administrators Roy Prouty and Randy Philipp.

A recording of the meeting is now available in Panopto at the link

You may need to be logged in to UMBC before, maybe on the VPN.

Remember to send me citations for papers as well as theses!

Thank you all,

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

chair, HPCF Governance Committee

This is just a reminder of our user meeting this Friday, 01/28/2022, 11:00-12:00. The following is the original post with more details.

For PIs, you may want to alert also other users in your group to make sure the information does not get missed.

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". 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 on 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
