similar to: optimal hardware for computations in R?

Has anybody here taken a HDD configured with an Opteron system, and then put it into an Athlon/64 and had it work? Are they interchangeable, like an Athlon/32 and a P3/P4? -Ben -- "The best way to predict the future is to invent it." - XEROX PARC slogan, circa 1978

I'm only now realizing that we have severe problems with R on our AMD 'Opteron' and 'Athlon64' clients running Redhat Enterprise with all 64-bit libraries (AFAICS). The Lapack problem happens for R-patched and R-devel both on the Opteron and the Athlon64. Here are platform details: o "gcc -v" and "g77 -v" both end with the line gcc version 3.2.3

Dear mailing-list members, In the days of cheap RAM and microarray applications feasting on memory, 64-bit computers become more and more useful - to actually make use of memory beyond the magic 4GB border. I would like to report the success of running 64-bit R on an Intel Xeon EM64T machine under Linux. Just like on an AMD Opteron, R v2.0.0 compiles fine (and out of the box) and is happily

Hey.. Has anyone played around with Asterisk on the Itanium2, Opteron or Athlon64?? Can Asterisk (or Linux for that matter) actually make good use of a 64bit system?? Later..

Hi All, Please for some advice. I have Linux router that do traffic control with HTB , routing and traffic counting. currently machine is with P4 2.2GHZ 1GB RAM. I plan to migrate to dual core CPU. I know well P4 dual core but is it anybody has experience with AMD64 dual core / or single core / for traffic control . I use Deban Linux for my router. Can I expect problems with HTB and iproute 2

From: Maciej ?enczykowski <maze at cela.pl> > That's a good point - does anyone know what the new Intel > Virtualization thingamajig in the new dual core pentium D's is about? It's all speculation at this point. But there are _several_ factors. But I'm sure the first time Intel saw AMD's x86-64/PAE52 presentation, the same thing popped into my mind that popped

I'm putting together a spec for a big(ger) memory x86_64 host, and I hope some of you-all can help. I'm looking for success stories of hardware that folks are using in production environments, preferably with CentOS 4, with more than 4GB of memory per CPU. I know there are lots of mobos out there that can do this, but I'm looking for what folks really have running. Call me

-march for clang and -march for llc do different things unfortunately. -march for clang at least on x86 is the same as -mcpu in llc. Which is an artifact of gcc compatibility. ~Craig On Sat, Mar 23, 2019 at 1:40 PM Doerfert, Johannes via llvm-dev < llvm-dev at lists.llvm.org> wrote: > Oh, my bad. > > > Idk why llc seems to know that architecture but clang does not. > >

Hi all, I want to buy a processor that will be good for gaming in Wine in FreeBSD. I see that many game engines are starting to take advantage of multi-core systems, however it appears that multi-threaded applications are not distributed properly across multiple cores (Ex: Starcraft II - http://appdb.winehq.org/objectManager.php?sClass=version&iId=20882 ). So I'm not sure if I should aim

I am planning to replace our cisco 7200 core router with Linux. We currently serve around 1500 (3/4 DSL - different router) customers with probably half of them being concurrent at any given time. We have a fiber network and customers currently aren''t managed as far as how much bandwidth they can use at anytime. Therefore I have constructed a working tc qdisc Linux router as a test. It

Currently I compile my C code in 2 steps in order to generate .o files clang -emit-llvm -c foo.c -o foo.bc llc -march=XYZ foo.bc -filetype=obj Is there a way to generate either .o or .elf files in just 1 command?

Hello, We have a few systems where udevd seems to failing silently on Opteron based Centos 4 boxes. Has anyone else seen this? -geoff

I'm spec-ing a development server for some Haskell hackers. In particular, they need to be able to build and run the Glasgow Haskell Compiler (ghc), the x86_64 port of which isn't quite there yet. My current thought is to get an Opteron-based system, but load it (initially, at least) with the 32-bit i386 version of CentOS. That buys me near-term ghc compatibility. In the future,

Assuming I have a firewire card with a supported chipset, is there anything special I need to do in order for the kernel to recognize the card? Shouldn't kudzu "wake up" and configure the card when I boot up after installing it? This is a brand spanking new 4.4 system and a supported Agere chipset firewire card. I'm having trouble tickling devices connected to the card.

Hello, I have this problem - I have installation of Xen and Centos 5 (all RPMs are from Centos repositories). I have several DomU virtual machines running on this machine. When I try to copy some bigger amount of data from another physical computer to Dom0/DomU on this machine, the network freezes. The link is still up, I can see that the connection really links on the switch, but nothing is

Hello! I need to purchase a new box, which I would like to optimize for good R performance. For the record, I will run Fedora Core 5 as and OS, and I wanted to know if anyone has experience with how the following affects R performance: - Is there a big advantage to having a 64-bit CPU over having a 32-bit? - Does an Opteron offer any advantages over an Athlon, and if yes, does it justify an
