Perl 3 years 30 weeks ago hi,
I've written a script which basically searches an entire (very extended) database to find matches and then perform some routine algorithms on it (it's a bioinformatics thingie :P)... the script itself works fine; the problem is the CPU Utilisation, or - in better terms - lack of CPU Utilisation...
I have access to a CentOS 6 web server running Apache 2 and MySQL 5 (I can find exact versions if that really makes a difference). This box has dual six core Xeons.
What I find looking over the CPU graphs is that the first two or three cores (0-2) hit 90% usage whilst the other nine are only reaching 30-40% usage.
Well I don't get why you would get a Multi-core processor if it doesn't. If I was using Just Ubuntu would multiple cores really matter as any CPU intensive things (Gaming as an example) that would use multiple cores are non-existent on Ubuntu.
I'm also talking about the Physical Limitations of Linux as a whole. Are there any Programs that use multiple cores?
I have a Dell server with two cpus, each cpu has 6 cores, and each core is hyperthreaded (i.e. should be equivalent to two virtual cores).
I am trying to run my program in more than one core. I have 12 cores in my desktop and want the computer to use 1,2,3,4,......,11,12 one by one and want to test how the program performs in different number of cores. I tried using -t4 or -t 4 after the executable like.
./a.out -t4
but I cannot make sure whether its using exactly 4 or not.
Hi,
I am very new to scripting and I wanted to write a unix shell script which can give me,
1)number of cpu's in a box
2)number of cores per cpu
3)total number of cores in abox (ie multiplying 1&2)
I am also trying to figure out how to check if hyper-threading is enabled in the server and also this check to script.
intially I am looking this to run on linux then wanted to implemen
I have a command to run (in this case is a php5 script) and I would like to know if there is something to run this command and select the core to be runed.
What I want to do is to run 1 command per each core to use the multiple cores of my server.
Any idea? Or I have to rewrite the script in other languages with multicore support and develop the core control directly in the script?
Thanks!
I am a new person here but I want to make an ssh server in Lubuntu on a pretty old computer.
I know that you can log in multiple ssh clients onto one ssh server computer. However, if you are running tasks logged in physically as a user ("George") on the server, then how will it affect the remote clients' logins to the server?
I have SQL Server 2008 Express running on Hyper-V based virtual machine with two vCPU-s. I've just been reading up on SQL Server 2012 Express and noticed that it's CPU is "Limited to lesser of 1 Socket or 4 cores" (http://msdn.microsoft.com/en-us/library/cc645993(v=SQL.110).aspx)
My question is how do the SQL Server 2012 limits on CPUs/Cores translate into vCPU-s?
