Running on Limited Power

February 10, 2020

Savio continues to run on limited power. The data center team is working with the data center facility to add more power, but this may take many weeks to complete. Many partitions have reduced nodes available and wait time maybe longer than previously. Thank you for your patience and understanding as we get service restored and expanded.


Savio back online

January 15, 2020

The scheduled datacenter electric work and storage system upgrade are complete. Savio is back online. Happy computing!


Scheduled downtime 

January 13 - January 16, 2020
The Savio system will be unavailable starting in the evening on Monday, January 13, 2020 at 5 pm through Thursday, January 16 at 5pm to facilitate scheduled datacenter electrical work and a storage system upgrade. The electrical work is a necessary step to prepare for the installation of the new SRDC system and to support provisioning of additional power for the Savio cluster in the coming year. We are taking advantage of the downtime to also schedule a significant upgrade of the Savio Scratch filesystem. This will provide us with tools to better manage scratch storage usage.
As with any storage work, there is always a very small risk of software failure so we are also reminding users to backup any critical data on the Savio Scratch filesystem as it is intended for non-persistent data.
We apologize for this long downtime and the inconvenience that it will cause but the work is critically necessary. If the timing of this outage is anticipated to cause major consequences to your research please write to us, we will do everything possible to find solutions that meet your needs.

Limited availability over curtailment

December 21, 2019 - January 1, 2020
During the UC Berkeley curtailment period, Research IT will offer only limited support for Savio and the other services. Please expect delays in responses to inquiries. In person consulting at weekly office hours will resume the week of January 6, 2020.

Savio back online

Monday, October 28, 2019 - 05:41
The emergency datacenter work scheduled for this AM is complete. Savio is back in production in a limited capacity as we requested and received an allocation of campus co-gen power to meet critical research needs. Users that had jobs still running as of this morning at 6am will want to check and resubmit their jobs.

Savio down on Monday, 10/28 due to power shutdown

Saturday, October 26, 2019 - 09:22
Based on information from campus leadership, we are expecting that PG&E power to campus will be shut off Saturday, October 26 due to the Fire Weather Watch and likelihood of high winds. For this outage we have been fortunate to receive an allocation of co-gen power from campus facilities such that Savio’s compute nodes will be able to stay operational and on line, available for service until Monday at 6am.
Monday at 6am we will bring down all Savio compute nodes with an expectation of service restoration by Monday 6pm. Job reservations are put in place such that there will be no jobs running in the queue after 6am on Monday. For all job submissions please choose appropriate wall clock times such that jobs finish before 6am on Monday or else they will be waiting in the queue until after the outage ends at 6pm on Monday. As before Savio’s login nodes and its data storage are on UPS and will remain up during the entire power outage.

Savio back online

Friday, October 11, 2019 - 15:09
Earlier this afternoon, we received word that the non-UPS power had been restored to the Warren Hall datacenter so we immediately started work to bring Savio back online. At this point, Savio is back in full production so users can return to doing their work. We did notice a few jobs were still running when we brought the system down before the power outage. Users should check their last running jobs and restart if necessary.

Savio still down: update

Thursday, October 10, 2019 - 13:39
While parts of the campus are running on power from the Cogen plant we have been requested to hold off bringing the Savio cluster back up due to concerns around overloading the generation facility. To this end we are waiting for clearance from campus facilities before beginning to restore service.
As soon as we have a green light to bring systems back up we will send out another note with an estimated time for service availability followed by a confirmation of service availability. Thank you for your patience as we navigate this outage. All hands are on standby to restore service as soon as possible.

Savio down on 10/9 due to power shutoff

Tuesday, October 8, 2019 - 16:37
Based on information from campus leadership, we are expecting that PG&E power to campus will be shut off on Wednesday, October 9 at 8am due to the Fire Weather Watch and likelihood of high winds. We will need to shutdown Savio starting at 6am. 
Users with access to other computing resources may want to copy their data over there as a precaution. Note that a PG&E outage at UC Berkeley will also affect LBNL computing resources too.

Update on Savio Status: Back Online

Monday, September 30, 2019 - 10:24
Datacenter staff finished repairs to the transformer this morning (Monday, 9/30) and were able to switch the power source from the generator to the house power. We paused the SLURM scheduler queues around 7:00 am today to shutdown all compute resources and allow the power switch from the generator to the transformer power. After that we were able to power back all compute resources and release the job queues at around 12:30 pm. We would like to thank all of our users for their patience and cooperation during this unexpected outage. 


Update on Savio availability from 9/24-9/30

Tuesday, September 24, 2019 - 16:37
As some of you might have noticed we were able to gradually bring BRC cluster resources back online on 9/23. Campus data center staff acted quickly and were able to provide us with alternative generator power as they continued their repairs on the broken transformer. Using this generator power we were able to bring Savio & Vector resources back to the level we were at the beginning of this week, i.e, Monday morning 9/23.
Data center staff estimate that the transformer will be repaired and ready by Monday morning 9/30 when we will have to switch the power source from generator to transformer back to house power. This will result in another half-day of downtime for BRC cluster resources sometime on or after Monday 9/30.
For now job queues have been released and many user jobs have been running in all the three generations of Savio and Vector cluster nodes (savio1, savio2, savio3). If the generator power and cooling remains stable we will be able to run at the current level until 6AM on Monday 9/30. 
Please reach us at if you have any further questions or concerns.


Savio unexpectedly unavailable from 9/23-9/30

Monday, September 23, 2019 - 15:34

Due to an unexpected power system emergency in the Warren Hall data center, Savio will be shut down from the evening of Mon, 9/23 until the repairs are complete on the morning of Mon, 9/30.


Savio back online

Friday, August 16, 2019 - 13:33

Update : Unscheduled downtime for BRC/Savio due to a power event in the datacenter

Thursday, August 15, 2019 - 15:23
Datacenter staff and electricians worked all day today to replace the burnt power circuit breakers with new parts, but they ran into some more issues. Their work has been extended into tomorrow as they need to wait for the arrival of some more parts. Unfortunately, this means that none of the Savio compute nodes are yet accessible via the SLURM partitions, but we hope to make them accessible by the end of tomorrow, assuming the electricians can finish their repairs early tomorrow morning, 8/16.
We just removed the login blocks so users can access login/front-end nodes, the DTN, and data on the filesystems, and we expect to keep this access open through tomorrow. 
We apologize for this disruption in service but we are doing our best to keep as many services as possible online. Email us at if you need any further help.


Savio partially online

Tuesday, August 13, 2019 - 11:05
BRC Savio cluster is partially online as of today 8/13 morning. Over the weekend multiple power circuit breakers got tripped in the datacenter and all Savio compute nodes lost power. As we tried to reset the breakers on Monday we realized some of the breakers are damaged and need replacement. But we managed to reset some other breakers and able to restore power in some of the circuits in the datacenter as of Monday evening. Our engineers managed to rerun the power cables from the compute nodes and network switches to the working power circuits and bring partial Savio cluster online. 
Datacenter staff are scheduled to take all the cluster offline again on Thursday 8/15 10:00 am to replace the broken circuit breakers. 
Savio cluster queues are now open for users to run jobs but only a small number of nodes are available in each of the Savio partitions. So we request only the users who have immediate deadlines to try to make use of the Savio cluster today and tomorrow and others please stay away from keeping the queues busy. Also note that due to next downtime starting at 10AM on Thursday request proper wallclock times (< 48 hours) to get your jobs running in the queues."
Email us if you have any questions or need additional assistance

Savio outage 8/12/2019

Monday, August 12, 2019 - 09:53
We experienced an unexpected power event disrupting power supply to all the compute nodes of the Savio cluster sometime yesterday, 8/11. Our engineers are in the datacenter early in the morning today making fixes and changes to the power layout and to restore services back online.
Right now users can login to the cluster front end nodes and access their data in the cluster filesystems but no jobs are running in the Savio cluster queues.
Once we finish power rebalance and bring nodes online jobs will resume running as scheduled before. CGRL's Vector cluster nodes are not impacted by this power event.
Reach us at if you have any questions or concerns.

If your have failed or incomplete jobs from either of these events please review them and resubmit back to the queues.
We are taking these outages very seriously and working with datacenter operations to improve the situation as soon as possible. This issue has been escalated with the manufacturer of the power infrastructure in the datacenter and they are planning to replace some equipment next Friday, Nov 10th. To accomodate this we have scheduled an emergency maintenance downtime to the BRC HPC cluster infrastructure starting from 7:00 am till 3:00 pm on Nov 10th.
All cluster resources will be unavailable to the users for the duration of this downtime. Job queues will be blocked so if you are submitting any jobs to the queues before Nov 10th make sure you request proper wallclock time such that jobs finish running before 7:00 am on the 10th or else your jobs will wait in the queue until after the downtime. Please pay attention to your walllclock requests and avoid getting confused on why your jobs are not running and creating support tickets with BRC help.
We apologize for these continued unplanned outages but we are doing everything we can to avoid these from happening in future.
