Applied Electronics Conference

javier — Sat, 16 Feb 2013 17:07:51 +0000

On September 25 to 27, UTN Bahía Blanca will host the uEA2013 conference. The event is an excellent place to meet students, academia, and industry related to electronics in Argentina. I hope to see you there!

#4 OpenCL headers [3]

There is a problem with OpenCL headers in Debian (it may be solved soon). Just downgrade the headers:
cd /usr/include/CL/ mkdir 1.2 mv cl.hpp ./1.2/ mv *.h ./1.2/ wget http://www.khronos.org/registry/cl/api/1.1/cl.hpp wget http://www.khronos.org/registry/cl/api/1.1/opencl.h wget http://www.khronos.org/registry/cl/api/1.1/cl_platform.h wget http://www.khronos.org/registry/cl/api/1.1/cl.h wget http://www.khronos.org/registry/cl/api/1.1/cl_ext.h wget http://www.khronos.org/registry/cl/api/1.1/cl_d3d10.h wget http://www.khronos.org/registry/cl/api/1.1/cl_gl.h wget http://www.khronos.org/registry/cl/api/1.1/cl_gl_ext.h

Our Work Presented at Shanghai!

javier — Sat, 19 May 2012 12:50:16 +0000

Our work was presented at Edu-Par 12. It was part of the 26th IEEE International Parallel & Distributed Processing Symposium (IPDPS) located at Shanghai, China.

NSF/IEEE Award!

javier — Thu, 08 Sep 2011 03:39:33 +0000

National Science Foundation (NSF) and the Technical Committee on Parallel Processing (TCPP) awarded me for a proposal about teaching parallel processing to undergrad students. The initiative is supported by the rest of the professors at UTN. You can see the complete list of the awarded initiaves here. Our material is here.

IEEE Roadshow at UTN

javier — Mon, 27 Jun 2011 00:21:54 +0000

We are encouraging students to get involved in IEEE activities at UTN. On June 29th, we are launching the activities.

Parallel Processing

javier — Thu, 14 Apr 2011 18:31:01 +0000

During the current semester, I will be teaching a Parallel Processing course at UTN. Check out the course website and let me know your feedback.

The Edges of Big Buck Bunny

javier — Tue, 01 Mar 2011 20:24:29 +0000

Here you can see a sample of the work we are doing on video processing. In this case we are using an edge-detection filter. The original material is available at www.bigbuckbunny.org

Arduino as a Learning Platform

javier — Sat, 30 Oct 2010 18:31:09 +0000

At UTN we are experimenting with Arduino (an open-source electronics prototyping platform). We see an interesting potential as a learning tool. Our priority consists on stimulating Electrical Engineering students to apply their C programming capabilities on real hardware. Pure fun!

Our Work Presented in HPC Event

javier — Sat, 11 Sep 2010 16:58:35 +0000

Last week I took part of the HPC 2010 Symposium. I found an energetic community that is growing year by year. We presented a work that shows some test we did using UtraSPARC T2 in visual computing.

The app in action

Debian GNU-Linux on 8-core UltraSPARC T2 Processor

javier — Mon, 23 Aug 2010 19:17:52 +0000

First of all, you got to boot from de CD-ROM. You got to deal with ILOM

> set /HOST/bootmode script="setenv auto-boot? false"
Set 'script' to 'setenv auto-boot? false'

-> set /HOST send_break_action=break
Set 'send_break_action' to 'break'

-> start /SP/console
Are you sure you want to start /SP/console (y/n)? y
Serial console started.  To stop, type #.

Once you reach the OK menu:

{0} ok boot cdrom

From that point, you install Debian as usual

More data at the HPC course I teach

We are running Debian GNU/Linux on a Sun SPARC Enterprise T5120 Server. The machine is powered by 8-core UltraSPARC T2 Processor. The machine supports 64 hardware threads. Lisandro helped me in this project.

Take a look at the output of htop command. We got a visualization problem
