Re: Trying to get an algorithm to run faster on RISC than wh

Thank you so much for all your help and input! Especially you guys that left me code examples. I'll have a look at it as soon we get the cluster working properly. :) We have a "side competition" now with two classmates that are working with a Zedboard. With 30 pieces they get ~27s and we are down to...

Re: Trying to get an algorithm to run faster on RISC than wh

One more question. In "Tasks" you can adjust the amount of memory in NEXT. What exactly does this do?

Re: Trying to get an algorithm to run faster on RISC than wh

It might be nice to convert this to BBCBasic and see where you get. Even better, see if you can re-write it in ARM machine code. This would cover the 'optimisation' angle as BBCBasic is better optimised for the ARM processor than the current 'C' compilers (never really a native language for RiscOS,...

Re: Trying to get an algorithm to run faster on RISC than wh

Maybe try Norcroft/Acorn C bundled as part of the DDE in NutPi: https://www.riscosopen.org/content/sales/nutpi - there is also a basic compiler too called ABC ! I've not tried it myself but have been told its beter than GCC - not sure if its 'optomised for the Pi' though - anyone? I'll try Acorn. T...

Re: Trying to get an algorithm to run faster on RISC than wh

its been a while since i've used riscos in anger, but afaik there's no way to give a task a higher priority like running it as root or nice'ing it like in linux. gcc is far from optimised on riscos, so i'd not be surprised if it was slower than linux. what sort of algo is it, as riscos doesn't have...

Re: Trying to get an algorithm to run faster on RISC than wh

We compiled them with no flags, so yes, "kind of".

Trying to get an algorithm to run faster on RISC than wheezy

Hei. For a school project me and a friend has decided to use the raspberry pi in different setups to see which one will run a specific algorithm (in C) the fastest. So far we decided to try different clock speeds (duh...), building a cluster and also try to run it on different OS's. I read about RIS...

Start xbmc the same way as ls or cp?

Hei,

I have installed xbmc on raspbian. The path to the .bin is very long and annoying so i wonder, is there anyway I can start xbmc the same way as when I run ls, cd or any of the other "standard programs"? i.e, just type xbmc and no matter where you are in the hierarchy xbmc will start?

Re: Tip for command line / terminal use

Use the * with care! I guess changing directory is not that big of a deal but using it when you delete stuff could go horribly wrong, since typing rm na* would delete every file in that folder starting with na! Only use * when you need to refer to more than one file. Using the auto complete option i...

Re: Tip for command line / terminal use

Would'nt pressing the tab-key also auto coplete? It does in "my" terminal.

If this thread catches on, I think it would be a good idea to edit the first post so it contains all the tips and tricks! :)
