Re: raspberry Pi, Nah - beaglebone black

kenner

Well, I went with a BBB after all. After preparing a list of what I would need to get started with a R-Pi, I realized the BBB would be cheaper.

Now I am awash in documentation on the HW and pins and GPIO and how to operate all that neat stuff. Anybody got any good links especially if Netrexx related?

My question concerns translating the python into netrexx. Are there any conversion programs out there?

You should definitely wait for a more definitive response -- I don't actually own a RasPi -- but if you can load the Python code into Jython, and then save the resulting class files, you could simply call them from NetRexx just like any other standalone class (or library).

No conversion would be required at all ... another benefit of running on the JVM.

There are really only two links you need:

I have tried the OpenJDK 6 and it works, but the Oracle distro is roughly 3X faster in my very informal, and totally unscientific testing with SciMark 2.0. The OpenJDK comes with the ZeroVM which is assembler-free and thus pays a performance price in exchange for portability.

And, depending on your intentions, you don't really need any hardware to get started. Connect the included USB cable (or any smartphone charger cable), and use ssh or PuTTY.

It's also reasonably important (altho' not vital) to upgrade the OS on the board. The instructions are all in the "Getting Started" info (also included). But the most important thing of all, and the real reason for any of this is to Have Fun!

There are OpenJDK builds with ARM JIT...
Although I don't have the link at the top of my head right now....

Probably something linked from here

Re: raspberry Pi, Nah - beaglebone black

Hi Fernando, and *all*:

Due to *my current STATE* of beeing handled like a 5 Year old Child, who
I am,
mentally, maybe, *by AUSTRIAN LAWS*, having a *CURATOR*, since nearly 2
Years now, I am:

*Totally unable to ACT (Financially, at least) here from Austria!

Capisci?
Comprendi?
Do You Understand, all, please ... ;-) ;-) ;-)

I *DO Have some 4000 Euro, *plus*, on my PENSION ACCOUNT, *I* currently
have to *stay ALIVE* with 50 Euro's by week, *which is not too much*!

Hence, I'm currently in *active Progress* to *RELOCATE* both my *own BODY*,
*my ancient HEAD*, as well, and *The rest of my tiny small BRAIN* ...

*to*

AFRICA, specifically The Gambia, namely BANJUL, to get out of this

(for me, atr least)

NO CHANCE TO SURVIVE (mentally) Situation and, shall then *continue*
to work as usual (when possible) *NOT FROM Austria*, ...

*BUT*

 From somewhere Elsewhere! ;-) ;-) ;-)

Sorry *to bother You all* with those, *my VERY personal* Problems, as
well as
*urgently to be resolved* issues (at least, for me ...)

Anyway, all the best greeting from here (Still Austria), which is, as well,m
currenlty *pained* by too much RAIN, the past weeks, thus ....

... SO MANY Families here in Austria do have, this Minute, much much *more*
Problems in *Their Lives* ....

THAN I do Have, at al!

Massa ThoMassa (relocatin to AFRICA, now ;-) ;-)(
==========================================================
PS: NeedLess to Say, from my Side, *I do hope, at least*, that *I* shall
Proceed
to *Finish* my *RexxForm* project, as most of the work is DONE, but, at
the minute,
I am *simply FIGHTING to be able to SURVIVE*, when possible at all !

Have a nice week, all, anyway ...
Thomas.

Re: raspberry Pi, Nah - beaglebone black

measel

Are you checking java on the mainframe under OMVS (USS ) ?  If so, that’s why.  It’s also why people are moving to z/linux to run their java.   USS was never very good performance wise but it did provide a place to run java on the mainframe.  Do you have zapp processors ?

Java Benchmark (was Re: raspberry Pi, Nah - beaglebone black)

Remember the religious wars that continue to rage about benchmarking in general, and any individual benchmark in particular. While not on the same scale as Emacs vs Vim, or Java vs CLR, they persist.

"Benchmarks don't measure anything." (To put it as simply as possible)
"Oh, yeah?"

The SciMark especially has a very tight focus: numerical calculations of the abstruse kind ... FFT, Monte Carlo, etc. It comes from the NIST (where they wind the atomic clock every day). Don't get fixated on bark, while most people see trees, and everybody else is admiring the forest. Cross-platform comparisons are especially troublesome. That's an apple and an orange ... from different planets!

I ran my "comparison" on the same hardware, changing only the JVM. And even I wince whenever I say -- especially out loud -- that one was "better" or "faster" than the other. I doubt that I'll ever do any of those calculations in anything I ever write anywhere ... so what have I actually measured? Elapsed time, perhaps ... and I didn't even measure it!

Are you checking java on the mainframe under OMVS (USS ) ?  If so, that’s why.  It’s also why people are moving to z/linux to run their java.   USS was never very good performance wise but it did provide a place to run java on the mainframe.  Do you have zapp processors ?

Looks like the mainframe is really slow. Or is it the difference in the version of Java?

 

Considering I would need a “Cobbler” on the Pi to do any breadboarding and I will have to have a RTC, the BBB becomes cheaper.

Re: raspberry Pi, Nah - beaglebone black

measel

If you guys are going to do much with java applications on Z, you may want to investigate adding a zapp.  One of IBM’s best values in my opinion.
