I have intel 2500k processor yet winsdk installed amd64 version for me. I can't seem to find a way to download intel64 version anywhere nor change the installation option. What should I do?
amd64 is the 64bit version of x86. IA64 is the Itanium version. You want the amd64 version for a 2500K.
Read this to learn why AMD64, Intel64, x64 are compatible terms.

I have installed intel compiler on my Ubuntu 18.04 machine through the following link: https://www.intel.com/content/www/us/en/developer/articles/tool/oneapi-standalone-components.html#dpcpp-cpp
I specifically installed Intel® DPC++/C++ Compiler for Linux.
I am trying to run some benchmarks and they require to source the path <icc_installdir>/bin/compilervars.sh but I can not find this file.
The installation says that Intel compiler was installed in /opt/intel/oneapi but I looked up this directory and there is no bin folder or compilervars.sh. Does anyone know how can I install this file?
Could you please try using the below command to initialize/source the Intel® DPC++/C++ Compiler for Linux?
source /opt/intel/oneapi/compiler/latest/env/vars.sh
And also, to confirm whether it is initialized you can check the version of DPCPP compiler by using the below command.
dpcpp --version

Does anyone know if it is possible to install lustre client software on a linux machine that has kernel 4+? From what I have experimented so far, all the working examples are on kernel 3.10. And if I try to install kmod-luster-client on 4+ machine, it fails with:
rpm -ivh kmod-lustre-client-2.10.5-1.el7.x86_64.rpm
error: Failed dependencies:
kernel < 3.10.0-863 is needed by kmod-lustre-client-2.10.5-1.el7.x86_64
kernel(PDE_DATA) = 0x44f0d59d is needed by kmod-lustre-client-2.10.5-1.el7.x86_64
According to lustre/ChangeLog in the b2_10 branch, it works with kernels at least 4.4.133-94.33 (SLES12SP3) and 4.4.0-131 (Ubuntu 16.04).
If you are using a newer kernel, you also need to use a newer version of Lustre. The lustre/ChangeLog on the tip of master (almost 2.12 release) reports support for kernels 4.15.0-32 (Ubuntu 18.04).
It looks like you are trying to install a binary kernel module RPM built for the RHEL7 kernel on a non-RHEL kernel. That is never going to work. You need to either get the right RPMs/Debs for your kernel from https://lustre.org/download/ or download the source and rebuild it for your kernel.
The 2.10.x kernels are currently the LTS maintained releases (bugfixes backported to that release), while 2.11.0 is a feature release that does not have bugfixes backported.
I have Red Hat Linux (Red Hat Enterprise Linux Server release 6.5 (Santiago) ) and yum in not working with message
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
No module named yum
Please install a package which provides this module, or
verify that the module is installed correctly.
It's possible that the above module doesn't match the
current version of Python, which is:
2.7.8 (default, Nov 7 2014, 11:45:08)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-11)]
If you cannot solve this problem yourself, please go to
the yum faq at:
http://yum.baseurl.org/wiki/Faq
Current version of python is 2.7.8
Any help is appreciated.
CentOS 6 ships with python 2.6. Someone installed an incompatible version of python system-wide and that has broken things. That should not have been done.
You need to find out how the 2.7 version of python was installed and fix that (by removing the incorrect package or by removing the source-installed python or by fixing the $PATH or whatever else is appropriate).
To help figure out what the problem is exactly we need the output from the following commands (as a start).
What does rpm -qa python\* say?
What does which -a python say?
First of all I want to note that I am booting CentOS from a flash drive (if it matters).
Now I am trying to install Nvidia drivers for my GPU but the problem is that I must update kernel-devel first. I did the following:
yum update
yum install kernel-devel kernel-headers gcc make
yum -y upgrade kernel kernel-devel
After that I checked which kernel I am using:
uname -r
Which gave me this: 2.6.32-431.el6.x86_64
Then I did: rpm -q kernel-devel , with the following result: kernel-devel-2.6.32-504.el6.x86_64
I tried to upgrade again, but it said "No Packages marked for Update
"
When I tried to install the kernel again, it said that I already have installed the latest version:
Package kernel-devel-2.6.32-504.el6.x86_64 already installed and latest version
Package kernel-headers-2.6.32-504.el6.x86_64 already installed and latest version
Package gcc-4.4.7-11.el6.x86_64 already installed and latest version
Package 1:make-3.81-20.el6.x86_64 already installed and latest version
Nothing to do
I am confused and I don't know how to make the lates kernel active, so I can install my Nvidia drivers.
Usually which kernel to use is selected via grub at boot time. If you have both installed its most likely that grub is still starting the older kernel.
You can look at /etc/grub.conf to make sure "default" is set to what you would expect. Default is 0 keyed off the "Title" entry.
Did you reboot? most of the time the latest kernel is set to default in grub.conf and a reboot is all you need.
Also https://serverfault.com/a/623755 might be the answer.
what is different between the following type i get qemu-kvm ? boths are use centos 6.4.
yum install qemu-kvm ,then show the version:
[root#centos6 qemu-kvm]# /usr/local/bin/qemu-system-x86_64 --version
QEMU emulator version 1.2.50 (qemu-kvm-devel), Copyright (c) 2003-2008 Fabrice Bellard
get the source code and build it by gcc.
[root#centos6 qemu-kvm]# /usr/libexec/qemu-kvm --version
QEMU PC emulator version 0.12.1 (qemu-kvm-0.12.1.2), Copyright (c) 2003-2008 Fabrice Bellard
Qemu uses 2 kinds of cpu virtualization, TCG (tiny code generator) and KVM. TCG emulates all instruction of guest code with plain c code, it translates guest code to host code in real-time. While KVM lets the host directly runs guest code, KVM requires the guest and the host to have the same instruction set (basically, the same cpu), not every cpu can do this, for intel cpus, it requires VMX feature. Which I assume you have understood these.
Qemu-kvm is obsolete, KVM comes with QEMU now if you download the latest code, you just have to compile it with "--enable-kvm" option. Your QEMU source code is very old, the latest version of QEMU is AFAIK, 1.7.
Your yum source provide 1.2.50 version of qemu. Try "yum install qemu", and try running with -enable-kvm if you don't want to build from source code (I haven't tried though)..
Qemu is Hypervisor.
KVM isn't. It is an accelerator(linux module which does the code translation fast) and used with Qemu, because Qemu when used with TCG is slow.
