How to set up R for Macbook Pro Intel Core Duo
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

rails hyperthreading on Quad core
Hi, my video sharing website (politube.org) that I developed with rails,
runs on lighttpd/fcgi (I know it is obsolete by now) and is severely
under load and regularly blocks because the lighttpd process chews up
50% of RAM (1GB).
So now I want to move the system to a new server with 8GB, 64bit ,
Quad core processor (intel i7 920) but I am not sure if hyperthreading
will really do anything better.

Question regarding digital card TE412p
Hi,
I was able to implement T122p one port PRI and was able to call out, but I
am planning to use TE412p (includes echo cancellation) 4 port digital card
(PRI), I wanted to know can asterisk support 3 four port PRI cards (12 PRI
connections) with proper hardware like dual core quadcore processor and 8gb
RAM in one server?
Also I was planning to implement using 64 bit architecture with Asterisk:

vcpus higher than real cpus possible?
Hello, i have just migrated machine to xen server where only 2 cpus are
available. I have copied config from machine where domU was located before.
That machine had 4 CPUS (QUADCORE), current machine has 2 CPUS (1 XEON
2cores).
I have forgot to change vcpus from 4 to 2 in config, but .. what really
surprised me ... machine started . How it is possible? It was really slow

Use of processor by R 32bit on a 64bit machine
Dear all,
I've recently purchased a new 64bit system with an intel i7 quadcore
processor. As I understood (maybe wrongly) that to date the 32bit
version of R is more stable than the 64bit, I installed the 32bit
version and am happily using it ever since. Now I'm running a whole
lot of models, which goes smoothly, and I thought out of curiosity to
check how much processor I'm using. I

Number of worker processes on hyperthreaded processor
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?

More Cores or more CPU Speed
Hi Guys,
in next week i plan to upgrade my Asterisk Server. To buy the optimal Hardware i have a question.
What is better more cores (eg. 2x quadcore) or more CPU speed for a server that handle a lot of of Meetme Concerences with hundreds of concurrent G711 alaw Channels (no transcoding) ?
in my opinion, more cores are better, because Asterisk ist multithreded and each channel has a good

HW experience
Hi,
we would like to establish a small Lustre instance and for the OST
planning to use standard Dell PE1950 servers (2x QuadCore + 16 GB Ram) and
for the disk a JBOD (MD1000) steered by the PE1950 internal Raid controller
(Raid-6). Any experience (good or bad) with such a config ?

Ubuntu vs Mac OS X
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

Too much init_sam_from_ldap...
Hi !
I'm working in a educational administration, i've made a domain with
a Samba 3.4.1 PDC with a LDAP backend. When a user log into an XP
Workstation, i see in the log file a lot of "init_sam_from_ldap". In
fact, instead of scanning only the user who try to connect, a lot of
them are scanned. I've got about 600 account into the LDAP so the time

Hallo list,
i am testing a Dell M610 with two quadcore Intel Nehalem CPUs at the
moment, so with Hyper-Threading 16 cores in total. As mentioned in the
subject I am using Ubuntu 8.04 64Bit and Xen 3.2 from Ubuntu package.
During these tests I hit on some issues, which are not clear to me. I

Estimado Javier Marcuzzi,
Francamente desconozco mucho de lo que me explica, no soy ingeniero, soy economista y tengo poca experiencia en R y sobretodo utilizando Mac. Tengo apenas 2 semanas con esta computadora.
Agradezco mucho su tiempo, seguiré investigando.
Saludos.

MacBook Pro Yonah (Intel Core Duo)
Dear all;
Has anyone tried the new CPU (codename Yonah) produced by Apple? I heard
from the engineer of Apple that MacBook Pro is already reachable, although
it is not distributed to the public until February. If anyone has some
information, I would like to buy it to enlarge the frontier.
-- Does Yonah demand xen/i86 or xen/ppc? Or we need brand-new source code?
That is the problem. Is

Using readBin to read binary "unformatted" output files from Fortran?
Hello,
I'm wondering if I can get some help with reading Fortran binary "unformatted" output files into R.
The Fortran output files were generated in Ubuntu 10.04 LTS using gfortran4.4, on a 32bit Intel Core 2 Duo 3.16 GHz machine, with little-endian and record marker lengths equal to 4.
The machine I'm currently trying to read this Fortran output file is a Macbook Pro
