What do you mean?

Can it run deep learning workloads?

The PS3 was used a few time in clusters – some NN work was done on it back in the day. My understanding (somewhat echoed in TFA) is that when programming Cell, you really needed to think about communication patterns to avoid quickly running into memory bandwidth limitations, especially given memory hierarchy and bus quirks.

For a while, it was a major player in protein folding. I remember the PS3 was particularly apt at doing that sort of work.

Eugh, maybe?
The PS3 only had 256mb of main memory so you'd be pretty limited there. Memory bandwidth, great at the time, is pretty poor by today's standards (25 gb/s)
So, I'd have to dig through some older notes I have, however, some of this information seems inaccurate based upon my own interpretation of the specs (and writing code...specifically, but not limited to, the PowerPC part). A suggestion from me is to provide sources, and also maybe an epub of this.
