Hi guys,

Thanks for your feedback on the performance
issue.

I wanted to know two things about userspaces.

1) How does one know which userspace one is working
on from the $ prompt.

2) Can we run a 64-bit application on a 32-bit
userspace with 64-bit Kernel?

Might be trivial for you guys but it would
really help me out.

Thanks.

A system running with a 32-bit kernel can only run
32-bit applications.

The 64-bit kernel can run 32 or 64 bit applications.

use 'isalist' to get a list of supported
instruction set architectures.  If you can
see sparcv9, then you're running a 64-bit
kernel

What would a "userspace" be?

Assuming you mean "kernel architecture", the isainfo -kv command will
tell you.

I don't understand the question. A 64 bit kernel will run 64 or 32 bit
applications, a 32 bit kernel will run 32 bit applications only. However
without knowing what you mean by a "userspace" I don't know whether this
answers your question.
