So I'm trying to buy a bunch of Orange Pi One's
http://www.aliexpress.com/store/product/Orange-Pi-One-ubuntu-linux-and-android-mini-PC-Beyond-and-Compatible-with-Raspberry-Pi-2/1553371_32603308880.html (http://www.aliexpress.com/store/product/Orange-Pi-One-ubuntu-linux-and-android-mini-PC-Beyond-and-Compatible-with-Raspberry-Pi-2/1553371_32603308880.html)
Have tried two credit cards (VISA + Mastercard) and both have been declined for "security" reasons.
Anyone else had this issue? I haven't encountered it before.
Anywhere else I can buy the Orange Pi One?

I had been wanting to try this, so I just ordered two. First attempt and the purchase failed saying "the card does not support the currency". Odd since the price was in Australian dollars and I was using an Australian card. About 10 minutes later, I tried to pay again and the purchase went through.

Do they take paypal?

Do they take paypal?
No, because they are bigger than ebay + amazon together and they promote their own payment system.

They used to take Paypal, but Paypal decided to refuse to let Aliexpress continue to use it. I think Aliexpress claimed at the time that this was due to the fact that eBay saw them as the competitor.

You saw that new one with the Wifi connector? Maybe get that one. The one single USB port on the $10 one with Ethernet is annoying.
Also, HMDI support on these things is not great. Maybe I'm doing it wrong, but as near as I can tell you need a specific script.bin for each mode. 1080p is one script.bin, 720p is another. HDMI to DVI is still another.
They are cheap though!

Is this for your SETI farm Dave?
I have about 10 x RPi2 here (repaired ones from TopLoser) that I might press into service in an old PC case with an old 10/100 switch/router and an old WiFi connection.
I've also got a <new> domestic solar panel (37v, 250W) - I might make it a solar powered search for ETI. Powered by a star, that's got a nice sound to it.

Yes, hence why as cheap as possible.

Perhaps you can post your questions on the Orange Pi forum?

You may be interested in this story from the register today:
This is what a root debug backdoor in a Linux kernel looks like
As well as all Orange Pi images except for Armbian's freshly patched 5.10, these vulnerable gadgets include ARM dev boards from FriendlyARM, SinoVoip (its M2+ and M3 Banana Pi boards), Cubietruck, and LinkSprite's pcDuino8 Uno.

Interesting, I'm curious how well it will perform. I had seti@home running on a couple rack mount servers, pretty grunty processors, but sadly seti@home is more gpu dependent, and even a mid range laptop gpu could have outdone the 800w of servers I had running it.

Most likely your bank has flagged the transactions as suspicious. Call your bank and tell them you authorize the vendor and ask to remove the block. Last time that happened to me buying parts from AviNet.

I know these Orange Pi's cost bugger all but wouldn't their very little work output actually make them terribly inefficient?
Wouldn't it be cheaper to use a GPU instead at least work done per Wh of power used.
There will be a few cheap secondhand nvidia cards in the next 2-3 months with 100's of times more power than a couple of Pi's

That's pretty much the issue I encountered with my setup too. I had two dual core 3.2ghz xeons, and another 3ghz Pentium running seti@home, and compared to a really crappy gpu it still sucked lol
They would use a whole lot less power though, and I suppose if you are someone like dave, a couple hundred bucks to try something out likely won't make much of an impact on your bank account, plus he can always switch to a gpu later and repurpose the pi's.

The xxx Pi's would certainly use a lot less power, but the power to work output ratio is where it's at.
As you said even a single crappy GPU smashes multiple x86 CPUs for performance per watt.
Same applies to the PI's (this is assuming the xxx Pi is doing the work and not offloading the it to another device (ie like the ASIC bitcoin miners)
I have several PI's and love them, they're just not the right tool for this job.
People are running PI clusters for SETI and other distributed computing tasks.
This is great for learning about Linux and distributed computing, and if this is Daves goal he should continue with chasing up some cheap pi's.
However if Dave, or anyone for that matter actually wants to contribute then a GPU is the only practical solution.
Setup is faster and easier too.

Yeah, there are quite a few CPU oriented projects as well, such as distributeddatamining and citizen science grid which properly make use of a cpu, and flourish on it.

Register Alipay, pay with that. I dont like the security, since all you have is a 5 digit pin, and you are registering in china, but you know, cheap stuff.

Can you use a cheap Android tablet for SETI? A nearby Target (Aus) store has one with a quad core CPU and 512MB RAM for about $20. It is the pink version of this one
https://www.target.com.au/p/pro-tab-7-8gb-quad-core-tablet/57563930 (https://www.target.com.au/p/pro-tab-7-8gb-quad-core-tablet/57563930)
You have to look around to find them and they are pretty crappy. It's only 20 bucks. I barely get 2 hours battery life playing video.
There is a BOINC app in the google play store so I don't see why not, but it would perform terribly.

I don't know, that's why I want to test it and get some actual data.

I'll let you know when I have the numbers.

You can probably run 50 Pi's with 200 cores for the power consumption of one video card.
Which cards are you referring too? And why will they cheap in a couple of months?

I've run SET@home on my dual processor Xeon with grunty Radeon R9 card, and also my 3770K with another decent GPU.
Yes is chews through the work, but the GPU only shows up as one processor out of the 8 or whatever working on one task. It is faster than the other GPU tasks, but not orders of magnitude.
-

Because 16nm nVidia cards are released this month, all the fanboys will drop their current 800$ cards like hot turds and eBay will be flooded with them.

Dave, I have a new Orange Pi which i purchased to test some boards with but never used it. I powered it up but didnt go any further with it!
Do you want me to post it to you?

Yeah, the gtx 1050, 1070 and 1080 look amazing, better performance than the titan x and half the cost, it's insane. Makes me wish I had a proper desktop all the same.

Yeah, but they are still insanely powerful, and at that price point, nvidia is going to dominate the market even more.
A 10ghz core would be just plain stupid though XD May as well make an OS designed to run off the gpu if it gets to that point.

I guess what i was trying to gently say is that unless SETI have some magic voodoo it is common knowledge among the distributed computing community that what you're trying to do is stupid and incredibly inefficient.
Using pi's or similar is a great way to get a feel for setting up and running a cluster, if this is what you intended, stick with it.
If you want practical and efficient results us a GPU, i'm a little out of date re SETI and several gen old video cards, so the other forume members can correct me, but i suspect an nvidia GTX780 might be a good starting point around $100
People have done is because they can and that's about it.
As mentioned above the nvidia Pascal cards were announced a few days ago with a global release on the GTX1080 in the last week of this month.
As also mentioned all those whom are super keen will drop their previous gen cards.

Yes is chews through the work, but the GPU only shows up as one processor out of the 8 or whatever working on one task. It is faster than the other GPU tasks, but not orders of magnitude.
The work units give to a GPU are packaged differently to those given to a CPU, also each processor is structured differently.
Also the GPU does not reveal each of its internal parallel units like the cores in an individual CPU package.
What you should be finding is that the R9 card (assuming it is something middle of the range or better) will be drawing the same or less power than the pair of Xeons and comfortably crunching the GPU specific.
Please forgive the rushed nature of these posts and lack of links to supporting data as i need to head to the airport.
I love SETI and F@H but my previous research says dont run it on a CPU, too inefficient.
I too love the raspery Pi, and the excellent cousins of it that have popped up, have previously read articls re dist computing on them, can be done, not efficient, pity i don't have a link i can throw.
Checkout the distributed computing forum on overclockers.com.au for more info, or simply post a thread there asking how to get the best bang/$ for SETI
Also on the side, by chance is the Xeon a dual socket 2011 machine?
Facebook recently let go of some server gear and there are Xeon E5-2670's going on ebay for ~ $100 each.
8 physical cores per CPU + hyperthreading and 20MB of cache
Could be a cheap upgrade if your board is compatible?
Gotta run, will read with interest in a day or so.

Got back home faster than i thought!
Looks like you're all set with the SETI forum Dave, i've had a quick look but am yet to find solid and current data.
I've still no doubt GPU is the go, but lack the memory and data to re-explain it, i hope the SETI guys can fill in the gaps.
You've re-sparked my interest and thus i'm now running SETI again on my GPU only.
Here is some info I've crossed re getting SETI up and running on the Orange Pi....

I have yet to configure it to run GPU only, but will do soon.
Will be cranking up the pair of 8 core Xeons for a few days out of curiosity, might make a nice heater for the man cave.

Yeah, dual xeons definitely heat up rooms pretty well, my dl380 g6 has two x5570's and the air coming out the back end is 53 degrees, it heats up a fairly large area quite well.

I can't help with your card, but I have used the Australia Post Load&Go travel debit card. It lets you store money in A$, US$, NZ$, Euros and British Pounds, so you can play the exchange rates a bit when buying from overseas. Handy when you want to lock in a price when the Aussie dollar is falling and transactions show up immediately on the website for the card. I have used it in the past with Aliexpress without any problem.

I've never used Alipay on Aliexpress, just the Escrow payment service available when you check out.
After the royal f*** up with PayPal a couple of years back I'm very reluctant to have my card details saved by a 3rd party. :--
After purchase you can select your card from a list, enter card details and authorise the payment/s if you've bought multiple goodies.
VISA works fine.
-
VISA works fine.
I've tried VISA and mastercard, both declined.

Did you call your bank? What do they say, do they see anything on their side?

Have you tried to buy from a different IP address in case there is some kind of credit card IP blacklist? The other thing is if you are on Telstra, they are having big overseas DNS issues, and perhaps it can somehow interfere with a credit card payment.
-
Do not waste your time and call your bank first. It is your bank who authorises card transactions.
-
Sounds like they need to change their name.
-
Apparently, IP address is one of the reasons for declining a credit card. It can either be because the IP address is on a fraud list or sometimes they check if the IP address matches the country. If you are using a VPN to connect to the Internet, that can definitely cause this problem. With the shortage of IPV4 addresses in Australia, perhaps some hosts are getting overseas IPs.

How do you go about running a program on a GPU?
-
How do you go about running a program on a GPU?
Search for "CUDA" as the main keyword to get you started. Lots of options, but all are targeted at programmers, not end-users. (This isn't a "run an arbitrary program on the GPU" situation, but rather "if you have an algorithm that can run efficiently on the GPU, here's the library to allow you to do so".)

The last attempt through AliPay must have got cleared somehow, boards are now on the truck :-+

They are cheap though!
The openelec port has fixed some of those issues. script.bin is not there as it is autodetected from EDID. Some boards still have issues with the eMMC booting if there is something other connected. The HDMI-DVI issues came from the forced on HDCP in default builds by orange pi (no copy protection information on hdmi port, no image).
