| 10:21.18 | RaYmAn | hmm, interesting: http://www.howchip.com/shop/item.php?it_id=ARNOctaA |
| 10:47.56 | projectgus | RaYmAn: wow, that looks complex |
| 10:48.02 | projectgus | be interesting to see how the OS support holds up |
| 10:48.23 | projectgus | he only heterogenous processor support in linux i've ever heard of was an academic experiment |
| 10:48.48 | projectgus | although it looks like the hardware support for caching will be sound |
| 10:49.01 | RaYmAn | afaik initially it only supports either-or mode |
| 10:49.05 | RaYmAn | e.g. either a15 or a7 |
| 10:49.08 | projectgus | i wonder how much RAM the board will have and how much it will cost |
| 10:49.29 | projectgus | RaYmAn: ah, so you boot into one or the other. That makes sense at least initially. |
| 10:49.34 | RaYmAn | well, no |
| 10:49.46 | RaYmAn | basically, you can switch over all processes to the other cpu set |
| 10:49.49 | projectgus | ah ok |
| 10:50.19 | projectgus | i guess that gives you a lot of the benefits without a lot of the complex scheduling and cache issues |
| 10:50.41 | RaYmAn | indeed |
| 10:50.45 | projectgus | well, with less of the complex issues :) |
| 10:51.15 | RaYmAn | in a dev board like this, it might actually make sense to run all 8 cores at once though - if nothing else, then use the a7 cores to offload specific tasks |
| 10:51.29 | RaYmAn | in phones or tablets with this chipset, it makes very little sense ;) |
| 10:51.52 | projectgus | yeah, well in a dev board it doesn't make much sense to bother with it at all. but obviously Samsung aren't developing for that :) |
| 10:52.31 | RaYmAn | the previous arndale is 249$, so hopefully it'll be lose to that price |
| 10:55.17 | projectgus | i suppose it makes less sense to have all 8 on for power at all, if the A15s have 3.5DMIPS/MHz, the A7s are 1.9DMIPS/MHz |
| 10:56.22 | projectgus | and the A15s will probably be clocked higher |
| 10:56.41 | projectgus | plus memory bandwidth & cache contention |

| 16:24.01 | L84Supper | http://phys.org/news/2013-04-adapteva-parallel-boards-summer.html |
| 16:24.18 | L84Supper | http://www.kickstarter.com/projects/adapteva/parallella-a-supercomputer-for-everyone/posts |
| 16:24.33 | RaYmAn | I regret not backing that one, heh. If they had been more clear on what you were actually getting, I would have. |
| 16:24.51 | RaYmAn | (the actual board is imo much better than the premise they sold it on =P) |
| 16:25.15 | L84Supper | xilinx hasn't posted official pricing yet for the zynq |
| 16:25.36 | L84Supper | yeah, they needed a bit of marketing help |
| 16:27.10 | L84Supper | http://www.parallella.org/wp-content/uploads/2013/01/parallella_block_diagram-1024x640.png |
| 16:40.35 | Undertasker | Atmel is selling combinations of ARM processors and FPGA's since many years, but with little success |
| 16:47.23 | RaYmAn | Undertasker: well, the fpga actually has a function in parallela =P but yeah, it can't have that many uses, other than a fun devboard |
| 16:48.28 | Undertasker | Atmel even released tools for sw/hw co-simulation, but nobody seems to be interested |
| 16:50.04 | L84Supper | the ZYNQ has been popular http://www.zedboard.org/ |
| 16:50.43 | RaYmAn | zedboard is fairly expensive though, isn't it? |
| 16:50.57 | L84Supper | ~$300 IIRC |
| 16:50.58 | Undertasker | As you said, a fun devboard |
| 16:51.10 | RaYmAn | 395$ |
| 16:51.18 | Undertasker | Never saw anything like this in an actual product |
| 16:51.35 | RaYmAn | compared to paralella at 99$ (ok, probably a bit more once it starts selling) |
| 16:53.21 | Undertasker | Too many toys on the market. |
| 16:53.33 | RaYmAn | There can never be too many toys :D |
| 16:53.48 | Undertasker | What would you use it for? Bitcoin mining? |
| 16:53.59 | RaYmAn | shrugs |
| 16:54.14 | RaYmAn | since when does having an actual usage for something become a requirement for toys? :D |
| 16:54.43 | Undertasker | Maybe interesting for video processing |
| 16:56.02 | Undertasker | 99$ isn't much for an fpga board |
| 16:58.03 | RaYmAn | especially one with a 16-core co-processor |
| 16:58.29 | Undertasker | I could do my own weather simulation with that |
| 16:58.52 | Undertasker | Does it come with a holodeck? |
| 16:59.13 | RaYmAn | I don't think they've shipped any yet, so it might! :P |
| 17:00.55 | Undertasker | Remarkably, that it doesn't have an Arduino compatible header |
| 17:01.35 | Undertasker | Everybody seems to think that he must be compatible with Arduino shields lately |
| 17:02.45 | RaYmAn | it makes sense in some classes of products |
| 17:18.58 | lejonet | is getting a parallella |
| 17:19.25 | lejonet | and I concur with RaYmAn, when did a realistic/actual usage scenario become a requirement for toys? xD |
