Whats the difference between 32bit and 64bit OS's or applications. I understand it a little but its just not clicking the way the teacher explained to me
thanks, any info would be much appreciated (1 Reply)
when using the command :
cat /proc/cpuinfo I get some basic info back on the cpu..
but it doesn't tell me if I am using a 64 or 32 bit processor ..
a) is this the right command to find this ?
b) if it is not what is ? and how do I get that information..
thanx moxxx68 (2 Replies)
Hi,
We are porting our application from 32bit to 64bit.
We tried -xarch=v9, -xarc=v9a and -xport64=full options so that compiler to issue 64bit porting warnings.
But we are not getting any porting warninings
WE are using CC 5.5 compiler on sparc-solaris m/c.
Please tell us some powerful... (0 Replies)
Where can I get a list that maps the each Linux version to corresponding 32/64 bits model?
e.g.
OS -> Model (ILP32, LP64, ...)
RHLE3 -> ?
RHLE4 -> ?
RHLE5 -> ?
...
It would be better if there is such a list that contains most of current UNIX OS versions.

Is there an 'easy' way to convert 32Bit code to 64Bit code. I have this benchmark i need to run on different machines and it would be nice if i could run it on the 64 bit machines ass wel.
The output when compiling(1) and running(2) are the following:

To make a programming language you need a compiler, so what was the first programming language and how was is created if you need the compiler first?
The compiler itself is considered as a high language comparing to the machine! since the compiler is not created in 1's and 0's...

i have solaris 10 x86 64bit installed on my pc (dell 3100). i then decided to move my hard drive to another pc (dell 4600). I noticed that each time i boot up, the OS show as 32 bit (instead of 64bit) and i can't even get past this stage to the login page.
when i moved it back to dell 3100 it... (13 Replies)
I have an application which builds and executes without error on a 32bit implementation of Linux. When I transferred the code to a new project on a 64bit implementation, the code will build without error, but the pthread functions, such as pthread_attr_setschedparam() return an 'Invalid Argument'...

Hi,
I have a C code which builds and works fine on 32bit linux machine.
Now i want to convert that code to build and run on 64 bit linux machine. I dont want to maintain two separate sources for 32 and 64 bit build. Same source should get build on 32 as well as 64 bit machine (when a... (2 Replies)

siop
SIOP(4) BSD Kernel Interfaces Manual SIOP(4)NAME
siop -- Symbios Logic/NCR 53c8xx SCSI driver
SYNOPSIS
hp700
siop* at mainbus? irq 3
siop* at phatomas? irq 3
PCI
siop* at pci? dev ? function ?
options SIOP_SYMLED
scsibus* at siop?
DESCRIPTION
The siop driver provides support for the Symbios Logic/NCR 53x8xx series of SCSI controller chips:
- 53c810, 53c810a and 53c815 (Fast SCSI)
- 53c820, 53c825 and 53c825a (Fast-Wide SCSI)
- 53c860 (Ultra SCSI)
- 53c875 and 53c875j (Ultra-Wide SCSI)
- 53c876 (Dual Ultra-Wide SCSI)
- 53c885 (Ultra-Wide SCSI and Ethernet)
- 53c895 (Ultra2-Wide SCSI)
- 53c896 (PCI 64bit, dual Ultra2-Wide SCSI)
- 53c1010-33 (PCI 64bit, dual Ultra160 SCSI)
- 53c1510d (PCI 64bit, dual Ultra2-wide SCSI)
The SIOP_SYMLED option causes the driver to report SCSI activity on the GPIO pin 1, which is connected to the activity LED on some adapters.
At this time only the 53c895 based Symbios and Tekram adapters are known to require this.
If both siop and the esiop(4) drivers are compiled, esiop(4) will take precedence for controllers it supports.
SEE ALSO cd(4), ch(4), esiop(4), intro(4), pci(4), scsi(4), sd(4), st(4), uk(4)HISTORY
The siop driver first appeared in NetBSD 1.5.
AUTHORS
The siop driver was written by Manuel Bouyer <Manuel.Bouyer@lip6.fr> for NetBSD.
BUGS
siop supports the 53c1010-33 in Ultra2-wide mode only. Use esiop(4) for Ultra160 support.
