psyco-dist not supported on 64 bit Linux

psyco-dist not supported on 64 bit Linux

[Ulf Samuelsson]

psyco-dist will not run on a 64 bit linux.
The guys behind psyco-dist recommends the use of PyPy

What is the recommendation for 64 bit linux?

Just run without JIT?
Don't run on a 64 bit linux?
Anything else?

Yes, not supporting 64-bit hosts is one of the known limitations of psyco. 
Being stuck with Python 2.6 is another limitation.

But, latest bitbake appears to be quite fast even w/o using psyco these days. 
Especially with parallel parsing on multiple cores...

OK, I will try without JIT then.

Now I have some results.

Building a custom x11 image on a 32 bit Ubuntu 10.10/psyco-dist  took 91 
minutes.
Building the same image on a 64 bit Ubuntu 11.04 without psyco-dist took 
109 minutes
(The last machine was an i7-920 w 4 GB RAM)
The first might be the same, alternatively it was a machine with 6 GB RAM.

= It takes 20% more time on a 64 bit O/S.

are these on same hardware running once 32bit or and second time 64bit OS ?

I have two core i7 machines
#1 Dell Studio XPS with a 2.67 GHz  920 + 4GB of RAM (2 channel)./Ubuntu 
11.04/x64
       The 109 minutes was measured on machine #1

#2 Homebuilt with a 2.67 GHz  920 + 6 GB of RAM (tri-channel)/Ubuntu 
10.04 x86
      Gigabyte UD5 Motherboard
      The   91 minutes was measured on machine #2.

Both are using the same type of disk Western Digital Black 1 TB
and have 1333 MHz memories.


I tried Ubuntu 11.04 / x86 on machine #1 using an external e-SATA 
Seagate disk
some time ago. I do not have the exact figures, but It was within minutes
of machine #2, so I think it is safe to assume that the extra time
is there due to the lack of JIT compiling.

End of this week, I hope to try on a 4.4 GHz (overclocked) Core-i7 
2600k/Ubuntu 11.10/x64.
Still only 1333 MHz memory unfortunately.

numbers on same hardware with different OS would be more relevant
for comparision
