similar to: Running R on a 64 bit processor

Hey all, I was planning on getting a new computer for the new year to help with my dissertation research, and recently had an opportunity to compare the performance of my 1.6 GHz Pentium M laptop, and a 2.8 GHz dual-core Pentium processor (both running WinXP professional 32-bit). I run a lot of long simulations, so I was hoping to get something that would speed them up. I ran a few quick

Dear All, I was wondering will there be any problems or changes that I will need to do to compile the current Asterisk(1.2.7)/Zaptel(1.2.5)/Libpri(1.2.2) source from www.asterisk.org into a 64-bit binaries? I am currently using the following hardware for my new server. CPU: Pentium D 930 3.0 GHz Mobo: Intel D945PSN Motherboard RAM: 512MB 533MHz DDR-2 Drive: SATA II Seagate 160GB Card: TE406

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

After doing some reading about 64-bit systems and software I am still somewhat uncertain about some things. I have a Dell Dimension XPS 400 with a dual core Intel Pentium D 940 (3.2 GHz) and 4 Gb of memory. I currently dual boot the system with XP Professional and Ubuntu 8.04 (32 bit). If I simply install Ubuntu 8.04 (64 bit) on this system will it run the 64 bit linux version of R? I would

Dear gurus, Three DELL SC430s were purchased by my company a few months back and I've been told that when they spoke with the DELL representatives, they were informed that these servers were fully RHEL 4.0 compatible. Specs of the servers:- - Pentium 4 - 2.8 GHz - 1 GB RAM - 2x 250GB SATA HDDs I tried installing CentOS 4.0 on it but it doesn't seem to be able to detect any hard

Dear R Users, I hope that there is someone who has an experience with a problem that I describe below and will help me. I must buy new desktop computer and I'm wondering which processor to choose if my only aim is to speed up R. I would like to reduce a simulation time - sometimes it takes days. I consider buying one of them (I'm working under Win XP 32 bit): 1. Intel Core2 Duo E6700

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

Hi I have a new ASUS A6Tc laptop with 1.6 GHz AMD Turion dual core processor. I get a strange error: <4>0000:00:0b.0 OHCI: BIOS handoff failed (BIOS bug ?) 000007b4 <4>0000:00:0b.1 EHCI: BIOS handoff failed (BIOS bug ?) 01010001 This only occurs when booting into the xen kernel, not without xen. Can someone tell me why and how it can be fixed? Art

Hi i'm planning to migrate a callcenter to asterisk and VOIP, the call center can have up to 25 cuncurrents agents logged in. I'll have some simplty IVR business logic and the some queues. Can a normal server with 1 GB ram 100 GB HDD Pentium 4 3.6 Ghz CPU Ethernet 10/100/1000 Support this? Would you suggest me a particular products? The server and the agents will be in the same LAN,

Hi all, i'm going to install asterisk with a 4 BRI (HFC chipset) on a Celeron at 2.6 GHz I don't known Celeron performance, but i listen that is not very good. Could I have some performance isuue with this kind of processor ? Thanks for all Giordano -------------- next part -------------- An HTML attachment was scrubbed... URL:

Good morning, The tuning page says worker_processes should be at least the number of CPU cores on a dedicated server. In the case of hyper-threading, should this be the number of cores or the number of threads? For example the Intel Core i7-2600 Quadcore[1] has 4 cores and 8 threads. Would I start my worker_processes at 4 or 8? Finally, would the same apply to Nginx worker processes? Many

reg2mem does not eliminate phi nodes the way codegen does, it just converts ssa values to non-ssa values. It's not the same thing.

Hi, Daniel I want to profile load/store operations, in order to reduce the overhead of profiling, I try to instrument the optimized llvm ir, which has phi nodes. BTW, when the value of some load/store operations may have multi-source, then the load will be translated into phi nodes, and all phi nodes are placed in the front of BB. Sometimes, the position is not where the load happens, is there

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

From RHEL docs: "The default implementation of LUKS in Red Hat Enterprise Linux is AES 128 with a SHA256 hashing. Ciphers that are available are: AES - Advanced Encryption Standard - FIPS PUB 197 Twofish (A 128-bit Block Cipher) Serpent cast5 - RFC 2144 cast6 - RFC 2612" My question is: What will be the performance impact on my Celeron 1.73 GHz CPU and/or hdd

Hi ! I have installed R-2.7.0 64-bits on a computer where the new Ubuntu version (8.04) was installed. This computer is a 3.2 GHz Dual-core with 2 Gb of RAM. To test how fast (I though !) this machine is, I compared two simple matrix manipulations between Ubuntu and my laptop (a MacBook Pro 2.2 GHz with also 2 Gb of RAM under Mac OS X 10.5.2). By the way, I install the normal version of R

Hi, Is FFT implemented in R takes advantage of multi-processors? I ran this benchmark from from http://www.sciviews.org, and AMD Opteron 2.2 GHz performs better than AMD Opteron 1.8 GHz on all test cases, except FFT operation. Both machines run same OSs (RedHat WS 3) and 2.2 GHz has more memory (2 GB RAM) than 1.8 GHz (1 GB RAM). The only difference is that 1.8 GHz is a dual-processor
