SARC 32 or 64 bit ?

czezz · 03-06-2008, 08:40 AM

How can I be sure is my SPARC is 32 or 64 bit ?

This is one of my machines Sun Fire V100:

Code:

bash-3.00# prtdiag
System Configuration:  Sun Microsystems  sun4u Sun Fire V100 (UltraSPARC-IIe 648MHz)
System clock frequency: 100 MHz
Memory size: 1024 Megabytes

Is there any better way to check that ?

Code:

/usr/bin/isainfo -kv

Hi czezz,

Ensure the OBP (open boot prompt) is up to the latest version, to find out what the current OBP is you can run the following:

1. At OBP, use the '.version' command. The firmware versions
displayed should be:

ok .version
Firmware CORE Release 1.0.18 created 2002/5/23 18:22
Release 4.0 Version 18 created 2002/05/23 18:22
cPOST version 1.0.18 created 2002/5/23
CORE 1.0.18 2002/05/23 18:22
ok

2. When running Unix, use the prtconf(1M) command. The version
displayed should be:

# prtconf -V
OBP 4.0.18 2002/05/23 18:22
OR

3. # prtdiag -v

(the absolute path is /usr/plat*/`uname -i`/sbin)

To obtain the latest version check out the sun.com web site.

I hope this is of help

If it's an "UltraSPARC", it's 64-bit.

Not to be a pain but the last answer is actually incorrect/misleading.

Not ultra-sparcs run 64 bit necessarily. I had an ultra 1 and a 2 that were running 32 bits. I had to change the jumper to support and run 64 bit.

Of course, solaris 10 does not run 32 bit on the sparc anymore. You can run 32 on x86. But that is a different story.

sun4u architecture (UltraSPARC/SPARC64) supports both 32 bit and 64 bit code. Solaris 10 is only released with a 64 bit kernel on SPARC but can still run 32 bit applications for obvious compatibility reasons.

To determine what kind of binaries your Solaris machine can run, try the following:

eden:/home/cph: isainfo -v
64-bit sparcv9 applications
32-bit sparc applications

You can see that this Solaris machine is capable of running 32-bit as well as 64-bit applications. If isainfo fails, running a 64-bit application on your Sun will generally not be possible, unless of course isainfo is not in your path or has not been installed. You can also use the uname command to glean more information:

eden:/home/cph: uname -a
SunOS eden 5.8 Generic_108528-05 sun4u sparc SUNW,Ultra-5_10

lagrange:/usr/users/cph: uname -a
SunOS lagrange 5.5.1 Generic_103640-29 sun4u sparc SUNW,Ultra-1

SunOS/Solaris versions map to the following:
SunOS SOLARIS
5.3 2.3
5.4 2.4
5.5 2.5
5.5.1 2.5.1
5.6 2.6
5.7 or greater is 64-bit compliant 2.7 or greater is 64-bit compliant

While all UltraSparc processors are capable of 64-bit computing, the OS release level may be the limiting factor. In the above excerpt, 'eden' (SunOS 5.8) is a fully compliant 64-bit platform, and 'lagrange' (SunOS 5.5.1) is a 64-bit UltraSparc limited to 32-bit computing.
