A 2-day OpenCL training on 13+14 October in Amsterdam for €500

openclbooksWhat you’ll get

For €500 you’ll get a two day training on OpenCL in Amsterdam. It handles just the basics on the concepts and start writing your first OpenCL programs. The goal is to take away the first obstacles for writing software for GPUs. You’ll learn unique insights from the StreamComputing team, you won’t read in any book.

The focus is on how to think differently – a CPU is not a GPU, and therefore many CPU-algorithms have to be written differently. Using group discussions, lab-sessions and lectures, we try to get you at the point where you are confident with the new technology.

We also included some basics of C such as how to work with #ifdef, pointers and file-handling. This should help people who have a background in higher level languages like Java, Python or dotNET. We start with simple examples, slowly getting harder and end the two days with an overview of what kind of algorithms can be ported (and what are the limitations) as an open discussion.

We won’t discuss more advanced subjects like OpenCL-on-FPGAs, debugging, OpenGL/DirectX, kernel-encryption, multi-device targeting and advanced algorithm design. Subjects like OpenCL 2.0, CUDA and OpenCL-on-CPUs will be lectured, but not practised. These subjects can be discussed during lunch or if you choose to join the dinner at the second day.

Why the split and affordable price?

During the past trainings we have learned a lot from the feedback. One was that we should split the training, as new concepts always take a while to land – a break would solve this. Another reason was that 4 days is too long to be away from a project.

With the split, we also have the opportunity to target a wider audience for the beginner’s course. To stress this, we lowered the price to €250 a day, including a book (one of the above), a charged travel-card for public transport (worth around €25), lunch, coffee/tea, cookies and fruit like apples and bananas (so you can tell at home you got a healthy training).

This training the base in GPU-computing everybody needs who wants to explore this new area. From there you can continue to learn yourself, take an advanced course from us, or take a follow-up course from another specialist.

Practicals

Location is 30 minutes from the airport, at Amsterdam Science Park. We try to get a location around 10 minutes from the airport.

You need to bring your own laptop, which has OpenCL running on it – we’ll provide you with information how to test your configuration. You can also rent one from us, for €100.

StreamComputing is at HiPEAC, Berlin

hotel-smallHiPEAC is the conference on “High-performance and Embedded Architectures and Compilers” to be held on 20 to 22 January in Berlin – tickets are still available, if you can spare three days. I (Vincent Hindriksen) would like to share the program I’m doing.

Edit: I met great people here and hope to see you next year (again).

StreamComputing is 2 years old! A personal story.

More than two years ago, on 13 January 2010, I wrote my first blog-post. Four months later StreamComputing was both official and unknown. I want to share with you my personal story on how I got to start-up this company.

The push-factor

I wanted to create a company which was about innovative projects –  something I had hardly encountered until then. The years before I programmed parts of A-to-B-flows, as I call them. That is software that is in the base quite simple, but tediously discussed as very, very complex.

“Complex” software

The complexity is not the software, as you can see. It is undocumented APIs, forgotten knowledge, knowledge in heads of unknown people, bossy and demanding people who friendly ask for last-minute architecture changes, deadlines around promotion-rounds, new deadlines due to board-decisions, people being afraid of getting replaced if the software is finished, jealousy if another team makes version 2 of the software, etc. The rule of office-software is therefore understandable:

Software is either unfinished,
or turned into a platform for unintended functionality.

The fun in office-software is there for analyst, architect or manager – the developer just puts in his earphones and makes all the requested changes (hooray for services like Spotify). But as I did not want to become a manager and wished to keep improving my development skills, I had to conclude I was on the wrong track.

StreamComputing flirts with ARM

 With the launch of twitter-channel @OpenCLonARM we now officially show a strong interest in ARM for compute. And we are not the only ones, as the twitter already has 80 followers (60 in 1.5 day and 12 retweets of the welcome-message).

ARM has made tremendous progress in both technology and market-share. With ARM-64, companies like NVidia (and maybe AMD) in the field, X86 seems to be getting a real competitor. This could happen because since a few years computers are fast enough and are not being replaced by a faster one, but a smaller one (tablet, phone) or extra one. By the rules of the market, current technologies are replaced by the ones that give those other needs. ARM is fast (enough), flexible in design, very cheap, low-power and passively cooled. The biggest obstacle seems to be only getting a standard for a docking-station to connect your mobile, tablet or watch to keyboard, mouse and large screen.

OpenCL is perfect for ARM, as it gives the computation-power to the intensive computations not already covered by hardware-support. In the world of X86 this interests high performance and big data companies, where on ARM this interests also more. Without the need for OpenCL you can already watch HD video, with OpenCL you can encode the video with MP4. This year you will certainly hear more about new possibilities of OpenCL on ARM.

What do you think. Why does Intel not sell IP to ARM-companies as many technologies could be reused? Could Intel be the next ARM as an IP-seller, or will they stay the defender of X86 for many years to come?

Happy New Year!

About a year ago this site was launched and a half year ago StreamComputing as a company was official for the Chamber of Commerce. It has been a year of hard work, but the reason for this all started after seeing the cover of a book about bore-outs. The result is there with a growing number of visitors from all over the world (from 62 countries since 23-Dec-2010) and new twitter-followers every week. Now some mixed news for 2011:

  • We are soon going to release a few plugins for Eclipse, both free and paid, to simplify your development.
  • 2011 will be the year of hybrid processors (Intel SandyBridge and AMD Fusion), which will make OpenCL much more popular.
  • 2011 is also going to be the year of the smart-phone (prognosis: in 2011 more smart-phones will be sold than PCs). So even more OpenCL-potential.
  • At 31-Dec-2010 we migrated the site to a faster server to reduce waiting-time also online.
  • The book will be released in parts, to avoid more delays.
  • There will be around ten (short) articles published in January. Both developers and managers will be served.
  • Our goal is to expand. We have shown you our vision, but we want to show you more.

In a few words: 2011 is going to be exciting! We wish all our readers, business-partners, friends, family and (new) customers a super-accelerated 2011!

StreamComputing – we accelerate your computations

Thalesians talk – OpenCL in financial computations

End of October I had a talk for the Thalesians, a group that organises different kind of talks for people working or interested in the financial market. If you live in London, I would certainly recommend you visit one of their talks. But from a personal perspective I had a difficult task: how to make a very diverse public happy? The talks I gave in the past were for a more homogeneous and known public, and now I did not know at all what the level of OpenCL-programming was of the attendants. I chose to give an overview and reserve time for questions.

After starting with some honest remarks about my understanding of the British accent and that I will kill my business for being honest with them, I spoke about 5 subjects. Some of them you might have read here, but not all. You can download the sheets [PDF] via this link: Vincent.Hindriksen.20101027-Thalesians. The below text is to make the sheets more clear, but certainly is not the complete talk. So if you have the feeling I skipped a lot of text, your feeling is right.

Our training concepts for GPGPU

It’s almost time for more nerdy stuff we have in the pipe-line, but we’ll keep for some superficial blah for a moment. We concentrate on training (and consultancy). There is a lot of discussion here about “how to design training-programs about difficult concepts for technical people”, or better: “how to learn yourself something difficult”. At the end of this blog, we’ll show you a list how to learn OpenCL yourself, but before that we want to share how we look at training you.

Disclaimer: this blog item is positive about our own training-program for obvious reasons. We are aware people don’t want (too much) spam, so we’ll keep this kind of blogs to the minimum. If you want to tell the world that your training-program is better, first mail us for our international partner-program. If you want the training, come back on 14 June or mail us.

OpenCL and CUDA are not the easiest programming languages due to incomparable concepts in software-land (You can claim Java is “slightly” different). Can the usual ways of training give you the insights and facts you need to know?

Current programs

Most training-programs are vendor-supported. People who follow us on Twitter, know we are not the best supporters of vendor locked products. So lets get a list of a typical vendor-supported training-programs, I would like to talk about:

  • They have to be difficult, so the student accomplishes something.
  • The exam are expensive to demotivate trial-on-error-students.
  • You get an official certificate, which guarantees a income-raise.
  • Books and trainings focus on facts you must learn.
  • It’s very clear what you must learn and what you can skip.

So in short, you chose you wanted to know the material and put a lot of effort in it. You get back more than just the knowledge.

Say you get the opposite:

  • They are easy to accomplish.
  • Exams is an assignment which you only need to finish. You can try endless times.
  • You don’t get a certificate, but you might get feedback and homework for self-study.
  • You get a list of facts you must learn; the concepts are explained to support this.
  • You are free to pick which subject you like.

That sucks! You cannot brag about your accomplishments and after the training you still cannot do anything with it; it will probably take years to actually  finish it. So actually it’s very clear why the programs are like this, or can we learn from this opposing list? Just like with everything else, you never have to just copy what’s available but pick out the good parts.

Learning GPGPU

If you want to learn GPGPU, you have to learn (in short) shader-concepts, OpenCL, CUDA and GPU-architectures. What would be needed to learn it, according to us?

  • A specified list of  subjects you can check when understood.
  • An insight story of the underlying concepts to better understand the way stream-computing works. Concepts are the base of everything, to actually make it sound simple.
  • Very practical know-how. Such as how to integrate stream-computing-code into your current software.
  • A difficult assignment that gets you in touch with everything you learned. The training gave you the instruments you need to accomplish this step.

So there’s no exam and no certificate; these are secondary reasons for finishing the course. The focus should be getting the brain wrapped around the concepts and getting experience. As the disclaimer warned you, our training-program has a high focus on getting you up-and-running in one day. And you do get a certificate after your assignment gets approved, so bragging is easy.

If you want to learn stream-computing and you won’t use our training-program, what then?

  • Read our blog (RSS) and follow us on Twitter.
  • Make yourself a list of subjects you think you have to learn. Thinking before doing helps in getting a focus.
  • Buy a book. There are many.
  • Play around with existing examples. Try to break it. Example: what happens if the kernel uses more and more local/private memory.
  • Update the list of subjects; the more extensive, the better. Prioritise.
  • Find yourself an assignment. For example: try to compress or decompress a large JPG using OpenCL. If you succeed, get yourself a harder assignment. Do you want to be good or the best?

If you know OpenCL, CUDA is easy to learn! We will have some blogs which support your quest on learning OpenCL, so just start to dig in today and see you next time.

The first steps have been made to create this company. The target is clear: serve customers in the more specialised fields (more than the usual office-applications) where mathematics and metrics are of importance. Most of our customers will have the expertise in a specialised field such as mathematics, physics, chemistry, economics and need extra power to use/sell their modelling-software.

Hardest target in the current market is finding those customers; since we can provide super-computers and -techniques at a tenth of the price it will be easier than our colleagues in the more expensive segment. Nevertheless the field is and will stay a specialised one.

Target-date is March 2010 to be open for customers. Hard work, but that is what we are made of.
