Allinea Forge is a GUI debugger and profiler for serial and parallel applications, which is now available on all clusters. In the past, PACE had “DDT”, which is a parallel debugger from the same company. Allinea combined DDT with a parallel profiler “MAP”, and rebranded the product as “FORGE”. For more information, please visit http://www.allinea.com/products/develop-allinea-forge

You can use Forge as follows:

module load forge/4.2.2
dtt      (for the debugger)
map   (for the profiler)

We still keep the old versions of DDT 3.1 and 3.2, which are available via module ‘ddt’, but we strongly recommend using forge from now on.

We have a shared ‘floating’ 128-core license for both tools. This means, when a user is debugging a 100-core run using DDT, another user can use up to 28-cores for either DDT or MAP.

If you are developing codes, DDT is a great way to identify bugs, memory leaks, etc (think of it as gdb in parallel with a easy-to-use GUI). If your code is working, but performing poorly, then MAP is the tool to profile the code and find the bottlenecks. PACE offers a debugging and profiling summer class (http://pace.gatech.edu/workshop/DebuggingProfiling.pdf), which partly covers DDT. MAP is a new tool for us as well, and we will include it in future sessions once we figure out how it works 🙂

These tools provide an intuitive interface for a shallow learning curve and targets all levels of users without requiring any specific expertise. So if you have any problem nodes, we strongly encourage you to give them a shot. If you still have difficulties, PACE team is always here to help you (and learn together in the process).

President G. P. “Bud” Peterson presented on the development of the High Performance Computing Center, which will soon begin the process of selecting a developer.

The Georgia Institute of Technology has taken another step to reinforce its commitment to support and enhance the Institute’s innovation ecosystem and economic development role in Midtown Atlanta’s Technology Square. The Institute, advised by Cushman & Wakefield, issued a request for qualification (RFQ) for private developers interested in the expansion of Technology Square.

Anchored by a high performance computing center, the development will be a transformative project providing a sustainable platform for expanding interdisciplinary research, collaboration and co-location with industry partners, while also supporting Georgia Tech’s academic and research programs in advanced analytics and computing.

In collaboration with NVIDIA, we are happy to announce the availability of *free* tokens for qwiklab classes for PACE users.

You can find a full list of available labs including CUDA (basics & expert), OpenACC and using GPUs in Matlab here:

https://nvidia.qwiklab.com/lab_catalogue

One nice thing about these labs is that they utilize Amazon Web Services (AWS) to provide each person with a GPU node, so you can try all examples and play with the codes on-the-fly requiring nothing but browser.

We currently have 40 tokens in total (NVIDIA promised more if there is demand) so please make sure you make good use of all the tokens that you requested and return them if you end up not taking the class. We allow for 4 tokens at a time, but you can definitely request more after you use all of them.

Here are the steps you need to follow:

1. Register at https://nvidia.qwiklab.com using your GT email
2. Email pace-support@oit.gatech.edu and specify:
– the email you used for your registration
– your PACE username
– number of tokens (4 max)
3. Repeat step #2 as you need more tokens
4. Provide feedback (each class should have a survey and NVIDIA folks repeatedly stated their interest in hearing from GT researchers)

Current tokens expire on June 3rd 2015.

Happy new year!

Free Supercomputing in Plain English (SiPE)
Available live in person and live via videoconferencing

These workshops focus on fundamental issues of High Performance
Computing (HPC) as they relate to Computational and Data-enabled
Science & Engineering (CDS&E), including:

* overview of HPC;
* the storage hierarchy;
* instruction-level parallelism;
* high performance compilers;
* shared memory parallelism (e.g., OpenMP);
* distributed parallelism (e.g., MPI);
* HPC application types and parallel paradigms;
* multicore optimization;
* high throughput computing;
* accelerator computing (e.g., GPUs);
* scientific and I/O libraries;
* scientific visualization.

Tuesdays starting Jan 20 2015, 1:30pm Central Time
(3:30pm Atlantic, 2:30pm Eastern, 12:30pm Mountain, 11:30am Pacific)

Live in person: Stephenson Research & Technology Center boardroom,
University of Oklahoma Norman campus

Live via videoconferencing: details to be announced

Registration coming soon!

So far, the SiPE workshops have reached over 1500 people at
248 institutions, agencies, companies and organizations in
47 US states and territories and 10 other countries:

* 178 academic institutions;
* 29 government agencies;
* 26 private companies;
* 15 not-for-profit organizations.

SiPE is targeted at an audience of not only computer scientists
but especially scientists and engineers, including a mixture of
undergraduates, graduate students, faculty and staff.

The key philosophy of the SiPE workshops is that an HPC-based code
should be maintainable, extensible and, most especially, portable
across platforms, and should be sufficiently flexible that it can
adapt to, and adopt, emerging HPC paradigms.

Prerequisite:
1 semester of programming experience and/or coursework in any of
Fortan, C, C++ or Java, recently

PACE is starting the lecture and training course offering once again.

Applications are now being accepted for Experiencing HPC for Undergraduates, a program designed to introduce high performance computing (HPC) research topics and techniques to undergraduate students at the sophomore level and above. The program introduces various aspects of HPC research at the SC14 Conference to increase awareness of opportunities to perform research as an undergraduate and potentially in graduate school or in a job related to HPC topics in computer science and computational science.

SC14 will be held Nov. 16-21, 2014 in New Orleans. Complete conference information can be found at:http://sc14.supercomputing.org

The Experiencing HPC for Undergraduates Program contains selected parts of the main SC Technical Program, with several additional elements. Special sessions include panels with current graduate students in HPC areas to discuss graduate school and research, and panels with senior HPC researchers from universities, government and industrial labs to discuss career opportunities in HPC fields.

Prof. Jeff Hollingsworth, co-chair of Experiencing HPC for Undergraduates, discusses the program and the need to develop the next generation of HPC professionals in an HPCwire podcast at: http://www.hpcwire.com/soundbite/toward-next-generation-hpc-professionals/

Applications must be submitted using the SC14 submission site at https://submissions.supercomputing.org/. The deadline to apply is Sunday, June 15.
