My $0.02: If you are not familiar with Linux then install the desktop version. I am familiar with Linux and I install the desktop version because most of the bloat that occurs is disk real estate. Example of why desktop is a good path for a newbie: On my fist foray into Linux I needed to configure my network. So I had a server install and followed an online readme that was quite detailed/accurate except for one thing. After following the instructions numerous times I still could not get my networking to function. The instructions left out one small detail: "After making these changes don't forget to restart your network to pick up your changes". If using the graphical this will not be a problem since the gui interface will do that for you. Learning a new OS has challenges and what you don't need to do is make it more difficult then it needs to be when starting out. As for the desktop robbing you of credits I would not be too worried. After all NONE OF US HERE CARE ABOUT CREDITS. RIGHT?!?! And lets also remember that some are crunching on Windows and no one seems to worry about loss of credits due to bloat. When using the desktop you can also do command line. Its a nice fit for a newbie I think. When your competent you can venture out with a server edition and command line your #$%^##$ off.
while i tend to agree the desktop is a good place to start for most folks. A running X server/sessions is a large resource hog on the micro machines this thread is intended for. on a "desktop" grade system its not going to affect anything.

good point. I sort of forgot this was a single board thread. Time to change the medications!!!
I've made some Progress with the RPI3-optimized BRP-App:
There are two Versions:
using Out-of-Place-FFT: does the job in ~21.5ksec, but needs almost all the RAM of the RPI3 when running 4 Tasks in parallel (~210Mb per Task).
using In-Place-FFT: does it in ~ 24.5ksec, but needs less RAM (~127Mb per Task)
Sorry for my late reply but the creation of both wisdoms need's much Time on the RPI (~250h for the In-Place-Wisdom and ~160h for the Out-of-Place).
I need a little bit more Time, to do further Optimizations. But I think I can share it with you by the end of the week.
BTW: Bad news for all Odroid-C2 users. It seems like the C2 only runs at 1.5GHz, as you can read here.
But that makes the performance of the Cortex-A53 running in 64bit mode even more impressive (The C2 @ 1.5GHz only needs ~13,5ksec). Hopefully the RPI-Foundation releases a 64bit-OS soon
PorkyPies passed 500k today. Congratulations to PG3.14 who passed 250k yesterday.
Good progress with the app optimisation, hope to see it soon. Mine are doing about 42k seconds a task so that's quite a speed up even with the in place FFT.
They aren't cheap at $295 (USD). While the rack seems okay from looking at it the power requirements are 7-48 volts as they have their own voltage regulation/power connections.
They have a single (the Uno Pi BB01A) a dual (Blade Duo Pi BB02A) and four (Blade Quattro Pi BB04A) as well. They appear, to me at least, to be a power supply solution for connecting multiple Pi's rather than a rack.

Was not aware of this offering. Interesting but as you note the price is a bit high for most of us crunchers. They also had a nice rack mount unit at ~$650.

Those are some nice numbers! Looking forward to the release. Thanks for your hard work.
That O2 mess is pretty bad. HK seems to be handling it well enough.
Cheers.

Has anyone looked at the Bitscope Pi racks?
They are aimed at industrial use but make a few models. They have a 10 Pi rack and a couple of others.
