Too bad I don't have an IPod or an IPhone. I would love to see if they could at least run Non-CPU intensive projects like Anansi, FreeHAL, or even QCN.

The main problem with that, is you can't have it running in the background. if you were able to port boinc and an app to run on it, the member would have to open the application on their device and leave it open. Reason for this, no multi-tasking. There are multiple other reasons there is not a valid port (speed of the processor, but i don't like that one, because i have an old p2 i use for testing).

Going through this thread it made me think:
----------------------------------------With drops you can create rivers, seas and oceans. With atoms you get molecules and with molecules drops. At WCG we need rivers, seas and oceans. So we have to start with drops and not atoms or molecules. This said in an IPhone of today there is more raw processing power than all of the computers onboard the apollo capsule and lunar lander together. One day (maybe in 15 years) we may very well land in our IPad the equivalent processing power of a top of the line quadcore desktop PC with a top 3D graphic board of today. It is a moving target. We have to look at how things evolve over time and be ready to integrate them when they are ripe and not before.  |

It appears the next step is a lot closer. According to this, Microsoft is looking into the multitasking arena for smart phones. Its not full blown, but is an important step.

Haha after reading this thread, I'll admit I'm intrigued with the idea of running grid applications on portable devices and I think it's worth trying. Of course, my intrigue has nothing to do any notion that it would somehow benefit the WCG's production directly, or even indirectly, but more based in a positive emotional/psychological response to the idea, which I could probably best characterize as 'cute.'
----------------------------------------For me though, the real sexy idea is crunching while NOT plugged in, which of course is even sillier in terms of output and capacity, but again it's more the idea of being able to walk around with something in your pocket doing work. Just the idea, that's all. At the end of the day though, I'm all about bottom line production baby! So yeah, let's not get too carried away with any suggestions that porting to mobile devices is an efficient use of time in terms of boosting grid production, but let's not lose that decidedly human quality of doing things for the heck* of it either. *edited to appropriate forum language - ErikaT  [Edit 1 times, last edit by ErikaT at Jul 9, 2010 1:10:16 PM] |

I would be more interested in an app for Tegra 2 (ARM9/ARM11/NVidia computer on a board) devices. Although it's not x86 compliant, apparently Chrome (a Linux based OS) is set to use Tegra 2. You can see it used with Android 2.1 here. These will soon be in mobiles, ee pads, TVs, consoles, net-top computers and other devices (Prototype). Over the next 18moths it is expected that over 1 Billon will be sold. We know these are very energy efficient but they are not slow either!
----------------------------------------I guess the dual 1GHz Cortex A9 cores are it's most promising feature, but it is also OpenGL compatible. Perhaps a Boinc app could be speciffically written for this Tegra 2 architecture. What do you think? [Edit 4 times, last edit by skgiven at Jul 9, 2010 8:45:47 PM] |

The iPad and the new iPhone have A4 processors, with the iPad running at 1 Ghz. Not too shabby! [Edit 1 times, last edit by Former Member at Jul 9, 2010 7:49:21 PM] |

----------------------------------------Yes, yes, yesteryear - hardly Tegra 2 Technology! There is little point developing something for 6months only to find it will be obsolete in another 6months. [Edit 1 times, last edit by skgiven at Jul 9, 2010 8:47:08 PM] |

What is the specs for 'flops' on these machines. Are they anything near to a CPU?

Well, its CPU performance is better than an Atom - perhaps twice as fast per core, and the GPU just trounces an Atom, but of course architecturally it is totally different.
----------------------------------------Cortex Family Architecture ARMv7-A Version Cortex-A9 MPCore Core: As Cortex-A9, 1–4 SMP cores Feature Cache (I/D)/MMU MMU+TrustZone Typical MIPS @ MHz In application - 10,000 DMIPS @ 2GHz on Performance Optimized TSMC 40G (dual core) (2.5 DMIPS/MHz per core) Cortex-A9 found in Texas Instruments OMAP4430/4440, ST-Ericsson U8500, Nvidia Tegra2, Qualcomm Snapdragon 8X72 4 peak SP Flops/cycle, for DP it is 1.5 Flops/cycle. Peak should hold well with out-of-order execution. "The Cortex-A9 power-optimized hard macro implementation delivers its peak performance of 4000 DMIPS while consuming less than 250mW per CPU when selected from typical silicon." So a Quad Cortex-A9 CPU would use 1W! [Edit 3 times, last edit by skgiven at Jul 10, 2010 2:43:42 PM] |
