Mathematica on a 256MB Model B

[dennisw]

For those who may be wondering, Mathematica works on a 256MB Model B, although sluggishly. I don't have a 512MB one to compare it to yet though,

Hi there, since using the X desktop doesn't use the GPU you could try changing the memory split in raspi-config.
Reduce the GPU memory to say 16 or 32 and see if that helps. That leaves more memory for Linux itself and Linux tasks to use.

Code: Select all

sudo raspi-config

Yes, it helps. Reduced GPU memory to 16MB and Mathematica works better on this " 'headless' 256MB Model B "

Would you mind testing wether W|A queries work? Just enter '==' (without quotes) and state your problem.

On my system, Wolfram tries to fire up Java for a minute or two, then stops with some error messages. I think this is due to too little memory.

Did a W|A query on Mathematica ( & Wofram ) ; they both appear to work on my 256MB Model B. ( http://goo.gl/tYSW2H

Ok, thanks for reporting!

Edit: Just noticed it needs to connect to the internet for certain tasks. Wasn't aware of this . Still, have to figure out what's wrong with my Java setup. No problem compiling and running applications from terminal or Geany.

Java starts up successfully with a GPU memory of 16MB, but is on the edge. I had one crash using Mathematica, and it was the first one in this Pi's life!

Fortunately a 512MB model is on its way to the german everglades .

There are alligators in Germany ... outside zoos??? Wow, global climate change has penetrated much further afield than I had ever imagined it could! Were you referring to somewhere North of Hamburg, e.g., the Nordsee area? Enquiring minds want to know!

Hi Jim. It's called the Emsland, basically a marsh. Somehow I stuck here . Oldenburg is the next civilized city, about 40 km away from me.

And we're still waiting for the global climate change, but with December and January more or less w/o temperatures below 273.15 K at sea level, there's a chance.

For what it's worth, I performed some benchmarking of Mathematica on the RPi and posted the results here. I observed considerable improvements with overclocking; however, there were negligible gains on my benchmarking functions with changing the memory split.
