similar to: Speed up R

I am looking at getting a new Thinkpad with an i5 processor. I was curious to what extent this would speed up developing a Ruby on Rails app. I am guessing that this depends to what extent multi-threading is utilized, but I am not sure---hence the question :^) If it is not that significant, my other choice would be to get a used Thinkpad or Mac Pro, duo-core. So is there a significant

I have been using a laptop computer of Pentium III 1.13 Ghz. I heard that AMD's Athlon has excellent floating point capacity. So I bought a Athlon 2200+ laptop yesterday. I expected that new Athlon 2200+ will be twice as fast as the P III 1.13 GB. I ran a R simulation program and the new computer is only 30% faster, in fact slightly slower than a Celeron 1.50 GB laptop. I am very disappointed

Hi all! I''ve decided to take the "big jump" and build a ZFS home filer (although it might also do "other work" like caching DNS, mail, usenet, bittorent and so forth). YAY! I wonder if anyone can shed some light on how long a pool scrub would take on a fairly decent rig. These are the specs as-ordered: Asus P5Q-EM mainboard Core2 Quad 2.83 GHZ 8GB DDR2/80 OS: 2 x

G?ran, thanks for the update, I'm just about to install it! Just wanted to drop you a short line about performance (as you once requested): aftreg takes ages on my windows machine to calculate a small set of 7 observations which are not even grouped together by "id". To be a bit more precise, it takes 2:40 mins on my Intel T9300 Core2 Duo @ 2.5 GHz. Bigger samples with about 700

Thanks for all the replies. Looking at the specs for the processor it does not seem to have the vmx features in /proc/cpuinfo: http://www.notebookcheck.net/Intel-Core-2-Duo-T6400-Notebook-Processor.35100.0.html and the output from grep -E ?vmx|svm? /proc/cpuinfo is empty. /lib/modules/3.10.0-229.7.2.el7.x86_64/kernel/arch/x86/kvm [keith.roberts at acer-centos kvm]$ ls kvm-amd.ko kvm-intel.ko

Okay, so I've done the requisite searching around, and I'm either missing something unbelievably simple, or something funny is going on here. I'm attempting to run a couple of simple games under Wine 0.9.57 in Gutsy on my new System76 laptop. When I attempt to run either of them, the loading graphic comes up, but the moment they attempt to change to fullscreen, X crashes. No warnings,

Hi R users Having both a faster CPU and more memory will boost computing power. I was wondering if only adding more memory (1GB -> 2GB) will significantly reduce R computation time?

I know this is a bit OT, but the subject of CPU speed came up here and I was (and have been for some time) curious: What is the actual speed of an AMD CPU? E.g., I have a Athlon 64 X2 "4200+" but my /proc/cpuinfo shows 1005.164 MHz for the two cores. What do those mean? Is there a reference for this (huge) discrepancy? Also, is there a way (and what) to tell what the actuall running

Dear, "Xenoppix-x86-64(Xen3.0.2+KNOPPIX-x86_64-5.0.1) CD size" is released. http://unit.aist.go.jp/itri/knoppix/xen/index-en.html Xenoppix-x86-64 exploits latest CPU (Intel Core2 Duo and AMD Athlon64). * Xenoppix-x86-64 boots both X86 and X86_64 linux kernel on HVM of Xen. * Xenoppix-x86-64 looks like KNOPPIX but all packages are replaced for X86_64. * Xenoppix-x86-64 also

lvm 3.7.0 treats pentium dual core ( cpu family 6 model 23 ) as "penryn" cpu, which triggers a serious bug : - crashs in openGL programs when llvm is used by mesa package, llvm will produces binary code with SSE4 instructions, which is not compatible with pentium dual core, because this CPU doesn't support SSE4 instructions ( bad cpu opcodes ), with llvm 3.6.2 this bug doesn't

I just recently purchased a Macbook Pro, Intel Core Duo 2GHz, 512 MB RAM. After looking through several articles in this forum I found the link to the R Mac Wiki. I am not that tech-savy but it appeared to me that this link, http://wiki.urbanek.info/index.cgi?IntelMacR describes how to install R on a Intel Mac Core Duo to utilise the two cores. I have also downloaded and installed the

Dear helpers, I am using R version 2.5.1 to estimate a multinomial logit model using my own maximum likelihood function (I work with share data and the default function of R cannot deal with that). However, the computer (I have an Athlon XP 3200+ with 512 GB ram) takes quite a while to estimate the model. With 3 categories, 5 explanatory variables and roughly 5000 observations it takes 2-3 min.

http://dovecot.org/tmp/concurrency.c I'd want to know what results this program gives with different systems. Please test and reply (but don't bother if someone already replied with the same OS+result). I expect it to print: - SMP kernels: "page size cut" once in a while - UP (uniprocessor) kernels: Nothing - The most important thing is that it never prints "broken

Hi again, I measured my fragment reconstructions against the compiler output from GCC and well - the new codes perform better, so I brushed up my gcc inline assembler skills and made a port. Code is here: http://torus.untergrund.net/code/mmxfrag.c All routines perform much better now. Inter2 alone got a speedup of factor 5 on Pentium-M. Athlon CPU's execute roughly 3 times faster.

Hi, I''m currently trying to use a Linovo R61 Thinkpad equipped w/ Core2 Duo for HVM Virtualization. BIOS shows CPU/Virtualization->enabled. Xen 3.2.0 shows (Xeo) VMX disabled by BIOS Does someone knows any problems with R61 Thinkpads?

Hello List Mates, I don't know if here is the right place for this question if it's not I will appreciate it if you can point me to the right mailing list. I have successfully installed KVM on my x86_64 laptop, however I am getting the following error when I try to connect "QEMU" from the Virtual Machine Manager Error polling connection 'qemu:///system': internal error

Hello, as said in the subject; I am having problems with ifcpu.c32 and ifcpu64.c32 detecting a Athlon II X4 CPU correctly as a 64Bit capable CPU. Ifcpu64.c32 does not detect PAE capabilities, also. Both boot the last (32Bit, non-PAE) entry. On two other Core2-based machines I have here, everything works. Can someone tell me what exactly these modules are looking for? Maybe I can compare that

Today I've got first video clips made by the camera and compressed "on the fly" - 1280x1024x30fps. Image quality is far from perfect - I don't have yet any way to preview images, and a single acquisition still requires a bunch of commands. So I'm really close to have a camera that will be able to serve the Ogg/Theora streams, now but will it be possible to play it on a PC? I

Chip Clock HT Cache Bus Speed --------------------------------------------------------- 5080 3.7 GHz YES 2MB 1066 MHz 5160 3.0 GHz NO 4MB 1333 MHz Does the .7 GHz and HT worth more then 4MB cache and higher bus speed? The application is VoIP so there is not a lot of IO so I would not think Bus Speed would matter. I am finding mixed information on HT, some say it is great, others say it
