I own an Athlon II X4, with 4 physical cores, and opensuse 11.4 x86_64 is only recognizing 1 of them. Although, when i disable ACPI from the BIOS, i get all 4 cores showing on cpuinfo.

I have a command line OCR program called OCR Shop XTR (Vividata corp) that I am using on a system with a 6-core AMD chip. I changed the bios so that the 6-cores were activated, but htop shows me that while the program is running, I am only getting activity on one core (the program maxes out the one core with consistent usage between 97% and 100%).
I have read that many programs are not written to take advantage of multiple core cpu's. However, I am just hoping that there is some way to get this program to take advantage of the extra cores. Does anyone know of a way to invoke programs from the command line which would spread the workload out among additional cores?

It's known that with previous iterations, up to and including 11.2, with certain motherboards ( I can only speak for Asus/Abit ) a quad ( or duo ) core cpu can only be installed with acpi-off or similar options; this leads to only one core running in OpenSUSE, although the board itself declares 4 cores run.And this seems to mean that various other unimportant ( for a desktop ) acpi functions are affected, including the os system clock.
Typing top or cat /proc/cpuinfo always shows only one core, and although the computer is fine, it seems a pointless state of affairs. Googling shows various suggestions, including removing acpi=off or noapic in the boot options and substituting pci=nommconf, or changing the kernel to an SMP kernel ( which is probably out-of-date as advice now ); still, I can live with it in 11.2: I just wondered if 11.3 addresses this installation problem. Or will any future editions address it ?Whilst one can live with it, the initial impossibility of installing ( with no clue as to why it shan't install ) must have put off a deal of people from even going forward with OpenSUSE ( or any similarly affected distro ).
OpenSUSE 11.2 installation DVD has many many applications that are installed by default.How can I install just the minimum for a working system. As an excercise I am trying to build a Nas system which I can install into our Windows Active Directory at work and have user access controlled via an Active Directory user group. I have no need therefore for so many of the applications available. I have tried uninstalling some applications and have managed to remove some features that I infact needed to keep.just a minor thing like the Gnome interface (gee!). Is there a list available of core applications required to function etc. that would help me to streamline my build?

I own a MB with H55 Chipset and a Core i3 540 with openSuse 11.2.I tried kernel 2.6.32 and 2.6.34 and the newest Xorg delete the xorg.conf and got a fine picture on the screen (same with xorg.conf and device "intel") Even HD MKV is possible. But in KDE I can only open one programm. If I try to open a second programm the desktop disappear and I get the KDM screen and have to login again and the former started programm is gone. Only if I start the programms via an open Terminal window the programms will run. I tried to delete all .kde(x) directories, but it�s the same after restart.Only if I use driver "fbdev" in the xorg.conf I get no problem. But then the screen is very slow.

I am trying to update Flash-player and yast2-core as prompted by today's update icon.
I am now faced with a loop that goes like this:
1) click on icon
2) window pops up, "2 packages selected"
3) click on apply, subwindow pops up
4) click on continue, "waiting for authentication"
5) after minutes of waiting, click on cancel, nothing happens
6) click on icon killing subwindow
7) now back to 2)
Aborting the process, starting at 1) again, same mess
Conclusions:
a) No idea what was going on
b) Use Yast instead of clicking update icon

With both 11.2 and 11.3 KDE Live CDs I get no graphical display when I attempt to boot into the Live system. VESA mode does not help either, only text mode works. So I installed the system in text mode but during the first boot the screen went blank again.
One peculiar thing is that 11.1 installs and boots fine, what gives? Is this even supported or I shouldn't even try to bother getting this setup to work? Has anyone been able to run opensuse 11.3 on a Core i7 integrated Intel graphics system with X system working?

System Monitor, Gkrellm and lscpu show just one when prior to the new install the old Wheezy showed both CPU's. I have put the hard drive into two other computers with dual core CPU's and all show just one CPU.
Interestingly System Profiler and Benchmark (hardinfo?) > Devices > Processors now show a large amount of processor infomation when with the old Wheezy I would only see both CPU's listed and nothing else.

I recently read in a forum that by default the Linux kernel only activates one of two cores in a dual core processor. Searching online gave one option to find out and that was the mpstat command. I therefore ran the command and got the following output.As the result says, it shows only 1 cpu. I was wondering what I could do to activate both cores in my machine, and whether doing so was going to cause me any problems.

View 5 Replies View RelatedI have created a virtual machine of a system running Fedora Core 4 and I need to upgrade it to Fedora Core 10. Based on what I have read, it iis possible so I started theupgrade process. I get an error message saying that /dev/hda6 (my root paritition does not exist) even though it does.
Does the installer need to read a label from /etc/fstab? I executed tune2fs -L / /dev/hda6 amd ,and added LABEL=/ for the corresponding entry for fstab. but the FEDORA CORE 10 is still giving the same problems for the installation process. Should I upgrade to an intermediate verson like Fedora Core 7 first?
I've a program that launches new processes, and wait for them to die before it exits. So, for example, my program is a process, and it launches 3 more processes, and when the 3 child processes end, it will exit.
As you see, at end of the example, the program used a total number of 4 processes.
1 - Now, I'm running this program in a CPU with 4 cores. This means that the program used each core for each process?
2 - How can I know which core the program used?

The installation shouldn't be a problem but I wonder how I can upgrade to kde 4.4, since opensuse 11.2 will have 4.3 by default? I saw in the documentation to add these repos:
# Core packages: http://download.opensuse.org/reposit.../openSUSE_11.2

whats the difference between core, community and playground? And isnt there "stable" repos for the KDE 4.4 release? And are there a repo with amarok 2.3 Beta?

I was bugging around with my nvidia driver and while reading README.txt I saw the following:
"NVIDIA has noted that in some distibutions, i2c support is enabled. However, the Linux kernel module i2c-core.o (2.4) or i2c-core.ko (2.6), which provides the export infrastructure, was not shipped. In this case, you will need to build the i2c support module. For directions on how to build and install your kernel's i2c support, refer to your distribution's documentation for configuring, building, and installing the kernel and associated modules."
So I checked if I have i2c-core.ko and I saw that it is not present as a built module, but only as a source code. So, my question is, is there any reason that the module is not shipped with openSUSE 11.3 x86_64 (I use the kernel HEAD repository)? Actually, does it make sense to use this module if I want to monitor the temperature of my GPU with sensors? How can I compile only that module and install it?
I want to generate core dump files from my program when it crashes. Its a pretty big process and has about 10-11 threads in it.I have followed the documentation to enable core dump by setting ulimit to unlimited etc. I quickly tried "A demo program creating a core dump" from the following webpage, which succeeds in Segfault and dumping a core file in the directory that I configured.However, I tried running my original program and caused it to crash. I did this by making calls to kill(), raise() or the same null pointer access as shown in the webpage above. In each case, my program crashed but did not generate a core dump file. Am I missing something?My program is in C++ and my environment is Redhat 9.0 (kernel 2.4.20)
Going through the "Why do I NOT get a core dump?" section on the same webpage as above, I can see two potential problems. One - there are issues with the suid/sgid (bullet # 6). I am not able to change any settings with suid because my system does not contain either /proc/sys/fs/suid_dumpable or /proc/sys/kernel/suid_dumpableTwo, my program has threads in it and the bullet # 8 is the problem.
We have a small cluster of 20 HP systems, all running CentOS 5.3 in an NFS-root environment. Half are quad-socket, quad-core Xeon E7340 @ 2.40GHz (total 16 cores), the other half are 8-socket, quad-core Opteron 8354 (total 32 cores). All systems have a Mellanox Infiniband adapter ("Mellanox Technologies MT25418 [ConnectX VPI PCIe 2.0 2.5GT/s - IB DDR / 10GigE] (rev a0)")
With kernel 2.6.18-128.1.6.el5, infiniband works fine on all systems.
With the update to kernel 2.6.18-164.11.1.el5 (and both types of node running the same NFS-root image), the 16-core Xeons still work fine. Infiniband no longer works on the 32-core Opterons. Specifically, either the ib0 interface fails to appear, or it does appear but when configured with an IP address, doesn't actually work. In either case, loading the IB kernel modules takes a long time, but I haven't instrumented the load script yet to see which module, if any, is at fault. More errors listed below.
However, if I tweak the BIOS of the 32-core systems to reduce the per-socket core count to 2 (so effectively 8-socket, dual-core, down to a total of 16 available cores), Infiniband starts working again. Putting it back to 32-cores makes it fail. Booting the older kernel makes it work again. In summary: old kernel, IB works on all systems. Newer kernel, IB only works on 16-core systems.
Updating the IB firmware from 2.5.0 to 2.7.0 (latest available) doesn't help. I also did a full 'yum update' to make sure that libmlx4, openibd all other associated packages were up-to-date. Doesn't help either.
Some errors that appear on 32-core nodes:
ib_query_port failed (-16) for mlx4_0
ib_query_port failed (-16) for mlx4_0
mlx4_core 0000:04:00.0: SW2HW_MPT failed (-16)
