This may be 'too much effort', compared to actually making sure that Stock actually works, but [is there/would there be] a way to tell, for ARM, which telescope the WU came from? (My instance is a smartphone, and it just shows basics like v7/v8 and 'task name'.)

On the phone, on the Tasks page, touch the circle with the arrow pointing to the right and it will show more details, including the Task Name. That starts with the date and tape ID. Beyond that, I don't know how to interpret the names.*

You can also get the task name from your phone's task list page here at the web site.


* I think that tasks from Green Bank will start with a letter code designating them as such; presumably, those from other scopes will have their own codes as they come on line. I surmise from that that tasks without such a code are from Arecibo.

The Aricibo names I'm sure you're familiar with :) The only others so far have been from Green Bank and look like this:

guppi_8bit_56520_VOYAGER1_0012.16007.1.20.23.49.vlar_8_0


This particular name is taken from the result file of a task done on the 12th Dec still sitting on one of my PCs for some bewildering reason :)
Mists of dreams drip along the nascent echo, and love no more.

End of line.

Bad news travels faster than the speed of light, good news never leaves the room.

I didn't catch the circumstances, since this involves an Android phone with a cracked screen, but I noticed one its tasks on main 'still' showing a memory message.

"As Far As I Know", the WU could have paused once, in switching between Main and Beta work, leading to that message.

Message 56825 - Posted: 18 Feb 2016, 11:37:34 UTC

I asked the question below on the SETI@Home Enhanced board but didn't get a response - anyone here know please?

In the last round of testing I joined an Android tablet up to Beta, in addition to my usual Windows clients. In the computer details it lists both a CPU and GPU (INTEL Intel(R) HD Graphics (535MB) OpenCL: 1.2). I can see, from the Event Log on the tablet, that it is requesting tasks for the GPU, but it's never got any.

Is there an Intel GPU app for Android? If there is, do I need to change/add a configuration file get it to work?

Any advice would be much appreciated :-)

Cheers

Until your post i'd never heard of Intel GPU support being available under Android,
generic GPU support under Android has been almost non-existent because of lack of manufacture provided drivers,
It's good to see that Boinc Intel GPU device detection does in fact work,
Regarding applications, i haven't heard of any Android Intel GPU apps being in development,
Since Android is fairly closely related to Linux, you could ask in the Linux/Beignet thread if Urs can supply an Linux app to Eric for deploying as a Android app and see what happens.

That must be some brand new development, i have not even read about OpenCL GPU support on Android so far. Only Linux on Arm devices has OpenCL support (Mali 600 and higher) as far as i know.

add: just checked SusieQ host and that device is not an Arm device, but some Intel Baytrail Atom GPU. And Android 5.0.1 claims to be based on linux kernel 3.10, which adds the Intel GPU support to linux.

GenuineIntel
Intel(R) Atom(TM) CPU Z3745 @ 1.33GHz [Family 6 Model 55 Stepping 8]
(4 processors) 	
INTEL Intel(R) HD Graphics (535MB) OpenCL: 1.2 	Android

If you have a couple spare minutes can you see what happened?

This is something I've notice on Main (As in, I decided to check a WU I'm a wingman on and discovered this through digging a little), but it looks like an Android 5.1.1 host is thrashing through a bunch of armv7-vfpv4 task with (for example):

<core_client_version>7.4.41</core_client_version>

I would really appreciate if someone would restart the MB v8 splitter. It's kind of hard to test my Android devices, when there's no work available.

There was a message posted today on one of the other News threads
The Linux and OS X OpenCL MB apps also have been updated, go testing.

Now the Linux OpenCL app has been updated I wondered whether there were any plans to produce an app for Android?

My tablet is nothing special - a Lenovo S8-50F - so there's probably more varieties out there that could crunch OpenCL tasks
