Parallel R for dummies (on hpc)
Hi,
I had access to an hpc cluster, and wanted to parallelize some of my R code. I looked at the snow,nws, rscalapack documentation but was unable to make out how I should submit my job to the hpc, and how I should code a simple program. For example, if I had 10 matrices, and 10 processor how should I write the R (and the hpc submit code) so that I run the calculations (e.g. rowsums) for each

How to charge for Asterisk installations and ongoing support?
Hi,
I'm just wondering how other people cost/charge for * boxes they have installed
in small businesses?
Asterisk is such a complex beast and is capable of so much it seems
equally complex to figure out a charging model!?
I'm contemplating installing a pair of servers at a small company with
two separate locations, one main aim is to provide a IAX link between
the two but I'm sure

Still a lot better than trying to run your own hodge-podge of nightmares on
Linux.

Confused setting up a "Virtual Server Hosting" config
Hi list,
Can anyone advise me on the correct/best set up for Virtual Server Hosting?

one public IP. I installed KVM on it and a guest. (both Ubuntu 18.04
LTS server edition). I am struggling to get the networking right.

Preparing for multi-core CPUs and parallel processing applications
Hello
I am fortunate (or in really big trouble) in that the research group I work
with will soon be receiving several high end dual quad core machines. We
will use the Ubuntu OS on these. We intend to use this cluster for some
extensive modeling applications. Our programming guru has demonstrated the
ability to link much simpler machines to share CPUs and we purchased the

Xen License
Hi Everyone,
This is going to sound silly but...
I''m just off the phone with a Microsoft SPLA reseller. They sell licenses to run Microsoft software in a hosted environment. I was asking about obtaining Windows licenses to run on my Xen VPS hosting solution.
Maybe there is a big misunderstanding, but I''m faily sure she said that it was illegial for me to rent out Xen

simultaneous computing
Hello,
which possibilities are available in R for simultaneous or parallel
computing?
I only could find biopara
(http://cran.r-project.org/src/contrib/Descriptions/biopara.html)
Are there other possibilities?
Are there special groups working on simultaneous computing with R?
Thanks

Problem with C extension
Hello,
I try to write an extension in C, to get a faster functions.
Therefore I have to add an element (vector) to a vector. The command in
R is very simple: x = c(x,a)
But in C I have the problem to reallocate my vector for getting more
space. Everything I tried, I get a "Segmentation fault".
So, how can I combine two vectors in C and give the result back to R
(return(x))?
Thanks

GUI that supports virtual PBX's/users
A friend of mine runs a small office building, 10-15 tenants. Each have
their own company, their own thing, renting space from him. His main PBX
is getting dated and his tenants are complaining. I was telling him about
Asterisk but his main concern is he doesn't want to have to always be the
one to add/remove extensions, or change the IVR hours or whatever.
Does anybody know of a free or

Rmpi and C Code, where to get the communicator

I try to write parts of my code in C to accelerate the for-loops. But
basic operations I want to do in R (e.g. start cluster). My R code looks

HP Proliant ML150 : how do I access disks ?
Hi,
Up until now, I've only installed Linux either on "desktop" hardware,
meaning one of the desktop PCs in the LAN acted as a server machine for
the network, or I rented some dedicated server somewhere in a datacenter.
Last week I bought some server hardware, a used HP Proliant ML150. It's
the first time I am dealing with this sort of hardware. The hardware was

SIP, IAX2 and ISDN ISUP data
Hi all,
I'm looking at my options for getting access to ISDN ISUP fields from
DDI numbers, when connecting to a 3rd party Asterisk server. This is for
a custom voicemail solution, and at this stage I want to avoid renting a
PRI.
The information I need to capture is:
- Calling Number
- Called Number (e.g. the DDI handling the call)
- Redirecting Number (e.g. the device diverting to the
