R and multithread
...ault R
math lib is single core). to compile R and make it use several procs on
the server. I'm not familiar with the different math libs availables
(BLAS,..)
Can i use faster math libraries so that R uses the full procs capacities
of my server ?
I'm running 2.12.2 on an linux server (16cpu with 32Gb ram).
thanks for your tips,

loess function takes long to estimate
Hi,
I have 2 questions regarding using loess function in stats package.
1. I have about 1 million points. I did loess with alpha=0.5 and
degree=1 and 2 regressors. It has run for more than 5 hrs on 64bit
16CPU and 64GB server (with no other process running). I am wondering
if this is usual? And if there is anyway to make it run faster?
2. I noticed a difference in RAM consumption when specifying loess
function differently. The first case is I ran loess(z ~
x+y,data=X,degree=1,alpha=.5) where my X has abo...

Question on trying to build R 2.11.1 on Tru64(aka OSF1) system
Hello,
I am trying to build the R-2.11.1 software for university faculty to use in
research projects on a DEC/Compaq/HP AlphaServer model GS160 16CPU/64GB memory
running Tru64Unix aka OSF1 version 5.1B-5.
Is it known whether it is possible to build the R-2.11.1 software on the
platform I am using?
In my attempts to build the R-2.11.1 software, I first used the native C
and Fortran 77/90/95 components and GNU make version 3.81:

alloc_heap_pages is low efficient with more CPUs
I am confused with a problem:
I have a blade with 64 physical CPUs and 64G physical RAM, and defined only one VM with 1 CPU and 40G RAM.
For the first time I started the VM, it just took 3s, But for the second starting it took 30s.
After studied it by printing log, I have located a place in the hypervisor where cost too much time,
occupied 98% of the whole starting time.
