Over 111 pages what was

Over 111 pages what was consensus of Parallella perspectives for E@h ?

What FFT sizes are usual for E@h tasks?

Parallella was a good idea

Parallella was a good idea and an amazing implementation at the time... However...

It had already been overtaken and soon became a dud with little follow-on support.

Instead, at that sort of scale and electrical power, we have the RaspberryPi, FPGAs, and RISC-V.

 

As I'm sure you're already well experienced with:

A higher power dud that similarly was quickly overtaken and is now abandoned was the Intel "Knights Landing" "Xeon Phi" "MIC" attempt. There are various of those once very expensive CPU cards now available for a $100 or so.

For high compute, AVX looks to have won for small scale SIMD / WIP whereas the AMD and nVidia big GPUs rule supreme for big SIMD arrays.

 

Have you a new optimised app experiment in mind?? ;-)

 

Happy crunchin',

Well, would be good, but first I should get sources and study them. It seems there are GW ones available currently, no binary pulsar search ones. And GW seems too demanding to run on anything small.

Turing Pi have announced they

Turing Pi have announced they are working on a V2 known as the Turing Pi2. The Turing Pi used 7 Raspberry Pi Compute Modules (up to CM 3+). It was a mITX board. The Turing Pi will hold 4 CM4 modules and also provide 2 x mini PCI, 2 x Sata III, a layer 2 managed switch, USB ports and is expected to use a standard PC power connector. See Turing Pi

Parallella was a grand idea but the author/designer "disappeared" into DARPA, and it just remains as a patented design now for an array of RISC processors. FFT would definitely have been it's main purpose for E@H. 

I had some big ideas once, involving a LEGO model of the dataflows, but it would require a processor array far bigger in size than was actually implemented in hard silicon.

Oooooh .... IIRC 222 is about right, that being about twenty minutes of the data stream from one of the GW interferometers.

Cheers, Mike.

The Raspberry Pi foundation

The Raspberry Pi foundation have released a fan to fit inside the official Pi case. See https://www.raspberrypi.org/products/raspberry-pi-4-case-fan/?resellerType=home for all the details.

Now here is a fan and a heat sync for an odroid n2 +  you will have to scroll down to view the heat sync and the fan.  I have two odroids.  one running einstein and the other world community.

Please need some help and guidance with what to do with the loss of the beta 1.47 NEON application that was used for BPR4 tasks that the new Android beta application caused to force the incompatible 1.06 application onto my Raspberry Pi 3B+

All tasks erroring out now.

Thanks.  I'll skip the anonymous platform for now.  They fixed the NEON scheduler issue and I just got 1.47 tasks again.
