So you're saying the people using PS3 clusters are just ignorant?

Not at all. Like I said, GPUs are not fit for every task and there are times when a PS3 cluster would be more efficient and effective. However, GPGPU if fairly new to a lot of people and they may not know too much about it/don't have the funding or time to sit down and relearn everything again. Instead, they decide to go with a familiar system, even if they have to get accustomed to the Cell processor.

Please stop putting words into my mouth.

Wait, what?  How is it a familiar system if they have to get accustomed to it? 

Also, when you said "There are tasks which GPUs are not fit for but most of the PS3 projects I've seen involve tasks which a GPU can do much more efficiently for much less", I don't think it's entirely unreasonable to conclude that you meant that (most) people using PS3 clusters were ignorant of the superior GPU solution.  Apparently that's not an accurate assessment of your position, but that's a reason why I sometimes rephrase someone's position and spit it back -- to see if I'm understanding it correctly.  I guess I'll avoid that technique with you, but I don't think I need to apologize for it. 

Systems with multiple CPUs have been around for decades. Although multiple processing units may be fairly new to games, multi-threading is the standard for scientific applications and other high performance applications. They are familiar with that system, they are just not familiar with the Cell processor. However, using the Cell processor for something that already scales well across multiple CPUs is not too hard. Using the Cell processor for something that is typically linear (games) is difficult. It doesn't take long to become familiar with it for those purposes.

I apologize if I seemed rude or angry, trust me, I'm perfectly calm. In the context, it seemed like you were saying that in a negative way, not as a question to clarify what I meant. I guess it's just one of those things that are difficult to understand with text. Had you said ignorant of a newer solution, then yes, I would have agreed. Calling them just ignorant sounded very negative.

That was an interesting post. I'm a little too busy to search online for something I saw a while back, but I will certainly do so when I get home in 2 hours.
