Frontera's /scratch1 filesystem currently has two of its Lustre storage targets offline due to errors on them and we are working with the vendor to restore it, but it might take some time. For now, the compute queues have been closed and the target has been deactivated on the login nodes to prevent hangs when trying to use the filesystem, but users will get errors if they attempt to access files residing on the offline target. If the repair will take more than a few hours, we will deactivate the target on the compute nodes and re-open the queues, however, jobs will fail if they try to access a file on that target. New files can be created on the other storage targets for /scratch1 without any errors.

Stampede2 /scratch Update Monday 2 March 2020The Stampede2 admins are working diligently to recover the /scratch filesystem. This recovery is expected to take at least one more day. We will provide an update after the filesystem has been recovered. Below is a repeat of the notice that went out on Thursday afternoon.TACC staff have deactivated the affected Lustre storage target on all the logins and compute nodes to avoid continued hangs when trying to access files residing on the offline storage target.This should impact less than 2% of the files in the /scratch filesystem, however, any attempt to read or write to a file on this target will result in an I/O error reporting "Cannot send after transport endpoint shutdown" and a listing of the problem files will show question marks for the permissions/ownership/size/date listing like this:# ls -l-????????? ? ?  ?      ?     ? job.1536_32NUsers should check their pending jobs to ensure that any files being read to or written to for that job are available in the filesystem without the above error message. Users will not encounter errors if creating new files on the filesystem. Also, if submitting new jobs, any input/output files or executables needed by that job (including shared
libraries) should be checked to confirm they are available before submitting a new job. The Slurm partitions/queues will be reopened at 2:00PM US Central time to allow jobs to run.TACC system administrators are continuing to work with the filesystem vendor to restore the offline storage target as soon as possible, User News will be updated with additional status updates.Please submit any questions you may have via the TACC User Portal.https://portal.tacc.utexas.edu/tacc-consulting

The Stampede2 /scratch filesystem recovery work is anticipated to take another 2-3 days before the filesystem is completely available again. In the meantime, TACC staff have deactivated the affected Lustre storage target on all the logins and compute nodes to avoid continued hangs when trying to access files residing on the offline storage target. 

 

This should impact less than 2% of the files in the /scratch filesystem, however, any attempt to read or write to a file on this target will result in an I/O error reporting “Cannot send after transport endpoint shutdown” and a listing of the problem files will show question marks for the permissions/ownership/size/date listing like this:

TACC staff continue to work on one of the storage servers for the Stampede2 /scratch filesystem, the Slurm partitions/queues will remain closed and users will encounter a hang if trying to access a directory or file that resides on this one server. An update to this user news will be made once the filesystem is restored to normal operation.

We are pleased to announce the BOINC@TACC Training being held on March 20th, 2020 from 1pm to 3pm CT.

The BOINC@TACC project is based on the Volunteer Computing (VC) model. It helps researchers in running applications from a wide range of scientific domains on laptops, desktops, tablets, or cloud-based Virtual Machines (VMs) owned by volunteers. With BOINC@TACC, students and researchers can run small high-throughput computing jobs (that is, the jobs that involve small amounts of data transfer and processing), without spending their active project allocations. 

Participants may attend in person at TACC or remotely by webcast. Participants in the Austin area are strongly encouraged to attend in person.

We are pleased to announce the HPC Application Tutorial: VASP on Frontera and Stampede2 Training being held on March 12th, 2020 from 1pm to 4pm CT. This new training module helps beginner and intermediate users of the VASP software package to carry out calculations with desirable performance and efficient usage of resources on TACC systems. It covers basic procedures for running VASP on TACC systems like Frontera and Stampede2, including:

- how to use a TACC supercomputer,
- how to gain access to the TACC installed VASP software environment,
- how to build VASP in licensed user's accounts for debugging, and
- how to build VASP in licensed user’s accounts with 3rd-party extensions.

The training also introduces the general steps for determining the task topology for optimal performance and scaling of VASP jobs under the TACC computing environment. Furthermore, we present and explain some of the most common issues and solutions to help users save effort in troubleshooting VASP related errors.

This training focuses on the system and computing environment aspects and how to run VASP efficiently on TACC systems. It is not a tutorial for researchers on how to use VASP to solve science problems. Users need to refer VASP manual and forum for that purpose.

This training is being made available to attendees via a live webcast. Registration for this event closes at 5pm CT on March 10th, 2020. To register and for more information please visit:

Please contact me at jasona@tacc.utexas.edu if you have any questions.
