We had an assignment at our college(bachelors study...) - that required the use of CUDA or OpenCL. I chose CUDA and it was rather fun. We already had a project made and we had to make it work in parallel on a graphics card. It was a ray tracing algorithm and I would definitely like to do something like that again.

are that you start noticing how similar they actually are. Eventually you learn a skill that makes it possible for you to change chip-sets easily. You start realizing that it is similar to programming languages, there is a couple of principles that stays the same. If you know these principles, you can pickup the ins-and-outs of any chipset very quickly. Then comes the art of writing code independent of any chip set, there are a couple of things which you can make independent, and a couple of things which you can't.
In my experience only a small percentage of the code in an application written for a specific chip-set will work on only that target chip-set... The rest of the code in the application is pretty much chip-set independent. Generally chip-sets follows a specific standard (e.g. C99) and if you keep to that standard the syntax of your code should work with any chip-set compiler, given that they follow the same standard.

I've got some neuron simulator code from years ago that would be perfect for several thousand processors.

I have started to look around at NVIDIA and CUDA, just wish I had more time to look into it.

Necessary being defined as:
- The target hardware has been specified
- The performance bar has been specified
- The performance bar cannot be reached on the target hardware using standard code.
In any other case, the (non)-portability of the resulting code makes it not worth the effort.
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.

AS previous comments, for embedded systems you have to target specific processor / hardware configurations

...because it's a pain in the bum, chips change, and 5 years later your chip-specific code is obsolete compared to generic code that may simply need a quick recompile with updated compilers.
However: I *love* that feeling of breaking out of the standard libraries and using features the average Joe can't use or doesn't know how to use. The secret little windy passage that leads to wonders...
cheers

1) Agree. It can be quite a headache every few years. But hey... try to compile VC++ v6.0 with MFC in .Net 
2) Agree as well, it is like the explorers of the 18th century. Being the first to achieve something out of the standard can be a big "high"

Arduino (Many flavors), TI's LaunchPad, Raspberry Pi, Beaglebone Black and want to get into more.
Love embedded programming and the only thing holding me back from other platforms is the expense of the IDE and I refuse to use Eclipse unless there is absolutely no other way.

 I hate Eclipse too... but you can always write code without an IDE or use another alternative.

True but haven't taken the time to learn, more than enough to get by about MAKE files.
Plus an IDE just makes it so much easier.

That's a fact.... I did enjoy my days working with VisualStudio. Working with Visual Studio for so long also makes me appreciate how crappy Eclipse really is.

Only if I would have to use that chip-set for myself. I wouldn't bother investing my time writing any program for chipsets even as an open-source.
I am more of a "write-once use-anywhere" sort of guy!

I agree but this doesn't always work well when your target platforms are vastly different. You can't write code that works well on a server with it's huge amount of resources and expect that to work well in an embedded device with limited processing power and RAM.

I wouldn't even bother thinking of the same thing, who would like to write the code for ASP.NET to run it on Arduino.
Raspberry Pi 2 is an exceptional case. I would love to write the code for ASP.NET website and host it on Raspberry Pi 2. Don't count Raspberry as a chipset? My bad.

... as such, until now, my challenge was always to make sure I could support the widest range of devices possible.
It's really the opposite of what is asked here, and I believe at least as challenging.

When you have to deliver real-time performances many subroutines may be thoroughly optimized. Where I work we have an assembler library with extra-optimizied functions to rotate and/or mirror 8 bit and 16 bit image buffers, plus I created from scratch a library to apply a normalization of the grayscale of those buffers. They all target systems from x86 to SSSE3, all Intel of course, with a function for every conspicuous change (all benchmarked of course).
If I'll change job I'd try to go for a similar one, where there is no everchanging bloated framework or the-next-big-thing-that-will-die-in-2-years.

Still I'd love to own an original Delta or Thema (I loved them both, but the Delta Evoluzione 220 hp and Delta HF Integrale were absolutely mind blowing).
