I fried a USB charger that was powering 4 Pi’s. I took the farm off-line as it was hot and I thought the heat was a contributing factor. The Pi’s have active cooling so I wasn’t too worried about them but the USB chargers I am using don’t have any cooling.

Finally think I have my RPI3 up and running but not without issues. Dumped a bunch of work because I guess the scheduler can't detect the differences between generations of Pi's'. Got sent the

application which errored out tasks immediately.  Looked around in the forums and stumbled upon messages that that application is not compatible with the RPI3.  So back to configuration settings and selected beta applications and moved the pi to a Home venue and I got the

Yes Keith that was the

Yes Keith that was the correct thing to do. The old app hasn’t worked since Raspbian Stretch came out (about 18 months ago).

The 1.47 is faster as it uses the neon extensions that the Pi2 and up have. Unfortunately that also means it won’t work on the earlier Pi’s.

No, there is no offical

No, there is no offical support for AArch64. But you can try some Things.

You could try my Odroid-c2 Version. It's compiled for Cortex-A53 but should run on a A57. As the ISA is the same. I tested it on some A72-boards for some Month's. Works fine.

Edit: Forgot the Link: https://einsteinathome.org/content/high-speed-linux-brp-app-odroid-c2

You could also try to install armhf-lib's and run the 1.47(NEON_Beta). You probably have to put a alternate platform in cc_config.xml

<options>
<alt_platform>arm-unknown-linux-gnueabihf</alt_platform>
</options>

 

But that uses only the CPU of the Jetson. The main powerhouse of this board is the GPU. BRP is open source. You could try to compile the BRP-CUDA or OpenCL-App(CUDA is probably better). I've got it running on a mali-GPU of a rk-3399. But I don't own a Jetson-Board, so I can not help much. You could send a PM to Gaurav Khanna. He is running a Cluster of Jetson's, he can probably help you with a binary.

Thanks for the info.  But I never saw a link to your Odroid app in the thread you linked.  Did I miss it somehow?

Also thanks for the referral to Gaurav Khanna.  I would like to run on the gpu since that is the most efficient way.  I PM'd him so will wait for his answer.

Try the first message of the linked thread, it's there. I get two pages for that thread, look for the second page at the bottom right above the message editor window. Wink

Another round of miracles by you :-D How is the performance of the T860, does it beat a fast x86 core? How much faster than one of the A72 cores of that board is it?

I'll be receiving an Odroid N2 tomorrow, featuring 4 x A73 (1.8 GHz) and 2 x A53 (1.9GHz) and 4GB RAM. The Amlogic S922X SoC comes with a Mali G52, which on paper is faster than the T860. So all in all a promising package. Would be awesome if its GPU could also be used as well.

I'll subject the N2 to some tests at different frequencies, I hope Amlogic learned from the S905 and those clocks are real clocks that even allow for a bit of an overclock...
