Are there any tools available in openSUSE for evaluating cpu/processor performance. My processor/cpu is under warranty til end of October, will like to know whether I need to get new one or i am good. I am looking for something that can log an event and report. Have tried stress and crashme but they dont show any results.
View 9 RepliesI need evaluate the ext3 file system performance; i need define:
- services provided
- parameters and
- the performance with different parameter values; for example, changin the value of the "data" parameter (journal, ordered, writeback).
I do not know what services ext3 provides. Well, i know intuitively that it provides services to read, write and erase files. But, there are anything more?. Where can i find the API?. Is the ext3 file system POSIX compliant?
I have a multi-threaded app using pThreads that runs great under Windows on my 4 core machine - all four cores get maxed out processing parts of a large file. I recompiled the same code to run on Red Hat linux on a 64 CPU machine - but from I can tell when it runs - it gets stuck on one core. "mpstat -P ALL" shows the cores are barely loaded. I have tried sched_affinity, sched_priority and SCHED_FIFO - nothing has helped. Any ideas on getting more performance?

It's listening on the default nessus port 9390. I am trying to connect to the nessus server instance using Open-VAS Client. I have generated the client and server certificates, I have pointed the client at the User Certificate File, the User Key File and I have a CA cert. I have created a user account on the nessus server. The problem is that when I try and log in from the Open-VAS client it keeps saying it can't connect. Is there anywhere I can check to see if it's being caught in a firewall, or where I can see if the connection is even making it to the server..

View 3 Replies View RelatedHow can i inspect and evaluate the mbr on a disk in a computer?
I'm interested in how to do this in general.
I can use gparted to see the partitions on a disk, but i don't know how to use it, or any other tool, to see just what is in the mbr.
The particular situation i'm in is that i have two disks in my computer. One has ubuntu 10.10 on a single partition, and one has 11.04 on one of 4 partitions.
The 11.04 disk used to be bootable, but somehow i messed up the disk: longer story: i installed another os on another partition, and the other os redid the mbr and installed a different version of grub, and i tried to reinstall grub but ended up with a disk that wouldn't boot. So i put my old 10.10 disk back into the machine so that i could at least boot and look around on the 11.04 disk.
Now, there are probably ways that i could recover the 11.04, but i would like very much to be able to systematically analyze the 11.04 disk to determine its exact current state before modifying it.
Since the disk is not mounted it seems like this should be in reach: i want to be able to (a) capture the mbr from the 11.04 disk [into, say, a file on the 10.10 disk] (b) get an analysis of what the mbr would do (where it points to etc, and what is at where it points to) (c) get any high level information which can easily be determined from (a) and (b).
I'm trying to do something like this:
Code:
#!/bin/bash
cmd1=$(cat /var/log/messages | grep -e 'blocked for more than 120 seconds' | cut -c 55-62)
if $cmd1 != 0; then echo 'okay'; fi
however i'm messing up somewhere... bash attempts to evaluate the elements in cmd1. when I try to run this script it complains saying:
Quote:
test1.sh: line 5: blocked: command not found
I am open to alternatives. My intent is to replace cat /var/log/messages with dmesg, so I can attempt to determine if a problematic application I use encounters a blocked state (unresponsive for more than 120 seconds).
Should I be using a different test condition? I tried something like:
Code:
# this declares cmd1 as an array
cmd1=($(cat /var/log/messages | grep -e 'blocked for more than 120 seconds' | cut -c 55-62))
#attempt to determine if number of elements in array is greater than zero
if ${#cmd1[@]} > 0; then echo okay; fi
But I get the same error... what am I doing wrong?
I just wanted to know if having my laptop set to ondemand, will this affect performance in any way? I realize it increases the clock speed to performance when the CPU is under load, but does the time it take to go from ondemand to performance affect speed? Will there be any noticeable difference between the two setups? I have a dual core intel at 2.2GHz when in performance. When ondemand is set with no load it downclocks to 800Mhz.

View 1 Replies View RelatedAm investigating processor affinity theory and practice, am somewhat surprised at the paucity of information on something that has been a part of many Windows Enterprise type applications for more than a decade and although I haven't investigated would assume is supported by big iron UNIX.What it is Processor Affinity is the *NIX terminology for "soft" assigning a process and its threads to a specific processor core. On multi-tasking machines and particularly those which run heavy loads it can be useful to "advise" the Scheduler to isolate/assign heavy loads to a core separate from other processes. I also have a specific situation where I would like to run more than one instance of a specific app, but cannot when sharing the same processing environment.
What I've found so far By default, any and all processes are assigned an affinity that permits running on any and all available processors.The taskset utility can be used to modify the affinity for any process, which means that once an application/service/process has been launched, only then can the affinity be modified.It seems that the RH platform may also have a utility called tuna which might provide some tuning capabilities in addition to setting affinity but does not seem to be in the SuSE repositories and I cannot find source.Is there a reference or utility that can launch an application with a specified processor affinity?

I never saw something like it, I guess it must be something with the underlying library not working on the new processor. I tried with slower memory speed, newest BIOS etc ...always the same errors. Other wise the system works absolutely stable.
When I compare the generated files with one created on the older system it looks like there are single bits missing in a random number of bites.
I consider building a new computer using a mainboard with support for two processors. I wish to do this to improve performance of course, specifically in regards to audio production. Though, what I would like to know is if anyone has some experience with using such a hardware on an ordinary desktop system and if there are some general implications I should be aware of?

View 7 Replies View RelatedFirst of all, apologies if this is not the correct place to post this. I recently installed openSUSE 11.2 (Gnome, 32bit) on my newish PC. It is an Acer Aspire X3200 (AMD Phenom X4 Quad-Core, 1.8 GHz, 4096 MB, NVIDIA GeForce 8200 Integrated, can provide detailed specifications if needed). I've to say I am very disappointed with the results so far! Sorry to say this but I'm having a whole load of problems that I never had when I had Vista or with current Win 7. Here are the issues:
1. Slow network performance. I've disabled ipv6 but it is still the same. Not only when I use Firefox, it is also slow when I use console based programs. 2. Instability - Gnome system monitor crashed 6 (or more) out of 10 times I use it. System Monitor users more CPU resources than anything else! Also when I started the PC this morning, I only had the desktop wallpaper. No icons, no taskbar, no mouse movements or menus, nothing. I had to force shut down it after a while. I'm sure we all are familiar with this on XP but I've never seen something like that on Linux!
3. Annoying noise coming every time I move mouse (mainly when scrolling) and even if I'm not doing anything. I suspect it is coming from my HDD indicator as it always blink even when nothing is running. This can't be a hardware issue as I've never had this on Vista or Win 7 (it is virtually silent on Vista and XP but not on SuSE) This noise is driving me totally mad.
4. Slow performance in general. No matter what I do, even typing this on this text window, it seems everything is running so slow. I never had this problem when I was running 10.x on my 6 year old PC. CPU is always running around 20%-30%, when I don't run any other applications but just Firefox (I have Foxclocks, Delicious and FEBE as add-ons and I don't have any problem using them on Vista or Win 7). I am using Compiz, not sure if this has got anything to do with that.
