OIT Network Maintenance, Saturday, February 25

Filed under: Uncategorized — Michael Weiner @ 2:31 pm

WHAT’S HAPPENING?

OIT Network Services will be upgrading the Coda Data Center firewall appliances. This will briefly disrupt connections to PACE, impacting login sessions, interactive jobs, and Open OnDemand sessions. Details on the maintenance are available on the OIT status page.

WHEN IS IT HAPPENING?
Saturday, February 25, 2023, 6:00 AM – 12:00 noon

WHY IS IT HAPPENING?
Required maintenance

WHO IS AFFECTED?

Any researcher or student with an active connection to PACE clusters (Phoenix, Hive, Buzzard, PACE-ICE, and COC-ICE) may lose their connection briefly during the maintenance window. Firebird will not be impacted.

This impacts ssh sessions and interactive jobs. Running batch jobs will not be impacted. Open OnDemand sessions that are disrupted may be resumed via the web interface once the network is restored if their walltime has not expired.

WHAT DO YOU NEED TO DO?

No action is required.

WHO SHOULD YOU CONTACT FOR QUESTIONS?
For questions, please contact PACE at pace-support@oit.gatech.edu.

Phoenix Storage & Scratch Storage Cables Replacement

Filed under: Uncategorized — Marian Zvada @ 5:33 pm

WHAT’S HAPPENING?
One cable connecting Phoenix Lustre device to controller 0 and second cable to controller 1, hosting project and scratch storage, both needs to be replaced. Individual cables will be replaced one by one and expected time to finish the work will take about 3 hours.

WHEN IS IT HAPPENING?
Tuesday, February 21st, 2023 starting 9AM ET.

WHY IS IT HAPPENING?
Required maintenance.

WHO IS AFFECTED?
Potential storage access outage and subsequent temporary decreased performance to all users.

WHAT DO YOU NEED TO DO?
Since there is a redundant controller when doing work on one cable at the time, there should not be an outage during the cable replacement. In case of storage unavailability during replacement becomes an issue, your job may fail or run without making progress. If you have such a job, please cancel it and resubmit it once storage availability is restored.

WHO SHOULD YOU CONTACT FOR QUESTIONS?
For questions, please contact PACE at pace-support@oit.gatech.edu.

PACE Spending Deadlines for FY23

Filed under: Uncategorized — Michael Weiner @ 1:48 pm

As you plan your spending on the PACE Phoenix and Firebird clusters for the end of Georgia Tech’s FY23 on June 30, 2023, we would like to alert you to several deadlines:

  1. Due to the time it takes to process purchase requests, we would like to get all prepaid compute and lump-sum storage purchases exceeding $5,000 by March 31, 2023. Please contact us if you know there will be any purchases exceeding that amount so that we may  help you with planning.
    1. Purchases under $5,000 can continue without restrictions.
  2. All spending after May 31, 2023 will be held for processing in July, in FY24. This includes postpaid compute jobs run in June, monthly storage payments for June, and new prepaid purchases requested after May 31, 2023.
    1. State funds (DE worktags) expiring on June 30, 2023, may not be used for June spending.
    2. Grant funds (GR worktags) expiring June 30, 2023, may be used for postpaid compute and monthly storage in June.
  3. Existing refresh (CODA20), FY20, and prepaid compute are not impacted, nor is existing prepaid storage.
  4. For worktags that are not expiring, your normal monthly limits on postpaid compute (if selected) will apply in May and June. Monthly storage will continue to be billed as normal.

Find out more about paid compute and storage services available on PACE on our website. If you have any questions or would like to meet with us to discuss the best options for your specific needs, please email us.
