We are pleased to announce the BOINC@TACC Training being held on May 10th, 2019 from 1pm to 3pm CT.

The BOINC@TACC project is based on the Volunteer Computing (VC) model. It helps the TACC/XSEDE researchers in running applications from a wide range of scientific domains on the 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. 

This training will be available to both in-person and remote attendees via webcast. Local participants are strongly encouraged to attend in-person.

We are pleased to announce the following two MPI training sessions being held on May 6th, 2019:

Intermediate MPI training 9am - 12pm CT 

Advanced MPI training 1pm - 4pm CT 

In our intermediate MPI workshop, we will cover the following aspects of MPI that go beyond basic point-to-point and collectives:

- Derived data types
- Communicator handling
- Process management
- MPI I/O

The workshop will alternate lectures with lab exercises, which can be done in C/C++/Fortran90/Fortran2008 and Python. Prerequisites: a mastery of basic MPI and use of Unix, including text editors.

In our advanced MPI workshop we will cover the following features that were added in MPI-3:

- Atomic operations
- Shared memory
- Non-blocking collectives
- Graph topologies and neighborhood collectives

The workshop will alternate lectures with lab exercises, which can be done in C/C++/Fortran90/Fortran2008 and Python.  Prerequisites: mastery of basic and intermediate MPI and use of Unix, including text editors.

These courses will be available to both in-person and remote attendees via webcast. Local participants are strongly encouraged to attend in-person.

The Stampede2 maintenance has been extended as we continue to resolve remaining hardware issues on a storage server in our cluster. We will announce via user news once service is restored and Stampede2 is back into production.

Stampede2 will be unavailable from 8 a.m. to 7:30 p.m. (CT) on Tuesday, 9 April 2019. We need to perform hardware repairs on a storage server after encountering problems today.


If you submit a job before the maintenance, and the time you request exceeds the time remaining until the maintenance begins, your job will run when the maintenance is over. The squeue command will report "ReqNodeNotAvailable" ("Required Node Not Available"). The showq utility will list the job as "BLOCKED" and report its status as "WaitNod" ("Waiting for Nodes"). Note that the hours leading up to the maintenance are an excellent time to submit shorter, smaller jobs that can complete before the maintenance begins: as the queues drain there will be many nodes available, and your wait time may be short.

The Texas Advanced Computing Center (TACC) will be deploying a new system, Frontera, in mid-2019, with support from the U.S. National Science Foundation as the first phase of the new NSF "Towards a Leadership Class Computing Facility" program.

This webinar will provide a brief overview of the plans for the new system and the broader project that surrounds it, review the architectural design choices made, and discuss the application community that will run on it. The presentation will also provide an update on the current landscape of systems at TACC, how they are used, and how usage is changing. 


This is the first of the upcoming series of Frontera training webinars. Please also join us for “MPI Foundations” on March 25 and “Programming for Advanced Architectures” on March 29. We’ll continue to send announcements for future Frontera training offerings.
