Is it possible to use both 64 bit and 32 bit instructions in the same executable in 64 bit Linux?
A 64 bit CPU (amd64) supports 32 bit Intel instructions in the compatibility mode. Also, a 64 bit Linux installation allows running ELFs containing 32 bit instructions if the ELF header says it is a 32 bit executable. I was wondering if it is possible to put some assembly instructions inside the ELF which swi…
Kubernetes on 32 bit machine
While I was running kubectl command in my ubuntu 16.04 os which is a 32 bit machine, I was getting cannot execute binary file: Exec format error Can some one tell me whether Kubernetes works on 32 bit machine or not ? Answer Currently there are no ready-made binaries for 32bit systems at: https://github.com/k…
Compiling for 32 bit on a 64 bit DMD
I am using xubuntu 16.04 amd64, and use the D Language. I used to use DMD i386 on a 32 bit machine (ubuntu 14.04), but now, for some reason, I can’t (or don’t want to) install DMD_i386 on my system, so I installed the one for amd64. All of my projects were written on a 32 bit machine, and I
select() fails when adding m32 flag to Makefile
i have the following code, which simply creates udp socket to listen to a multicast group. I’m compiling it using gcc, with -c -g flags, on x64 machine. When adding -m32 flag to linking & compiling phases in Makefile, select() call is failing with Invalid Argument. After debugging a little bit with …
What is the systematic way when I want my code (client and server ) work on various scenarios?
I developed in on 64-bit MAC. And I wish it would work under two scenarios: 64 bit server and 64 bit client 32 bit server and 64 bit client ONLY DEALING *NIX NOW Between the communication of server A and client B, I would exchange a linked list of struct, which is of the following type: both size of char
32-bit to 64-bit jvm migration – jboss web application & linux server
We are migrating our Java EE / JBoss web application currently running on 32-bit linux box & 32-bit JVM to 64-bit linux box & 64-bit JVM. We analyzed & changed the JVM heap, permgen, stack etc., sizes appropriately. Is that enough or should we consider any other parameters/ make any other changes …
java.lang.NoClassDefFoundError: Could not initialize class java.awt.Toolkit
I’m working on XUbuntu 13.04 and developing swing applications. As I just wanted to try that application I ran into java.lang.NoClassDefFoundError: Could not initialize class java.awt.Toolkit on startup. I’ve found several questions about server/client vms and noticed that I have a server VM and t…
Allocate more than 2GB on the heap using c++ on a 32bit linux kernel
This seems to be a very common problem, but still I haven’t found a definite answer. I have access to a server which runs linux, has 16 GB of RAM and a 16-core (64bit) CPU (/proc/cpuinfo gives “Intel(R) Xeon(R) CPU E5520 @ 2.27GHz”). However, the kernel is 32bit (uname -m gives i686). Of cou…
32-bit process’s address space on 64-bit linux
In this answer author states: With the 64-bit x86_64 kernel, a 32-bit process can use the entire 4GB address space, except for a couple pages (8KB) at the end of the 4GB address space which are managed by the kernel. What is the purpose of this kernel-managed memory? Shouldn’t it be in the kernel space, to pr…
