c/c++ Random Number Generators Benchmarks using OpenMP
...r the
different available RNGs, except for the rngOpenMP that is not
instantiable, so I adapted specifically the code.
I included in the benchmark:
- the c implementation used by the R package Rlecuyer
- the (GNU) random_r RNG available on GNU/linux systems and that is
reentrant
- my RcppRandomSFMT,wrapping a modified version of the SIMD-oriented Fast
Mersenne Twister (SFMT) Random Number Generator
provided by http://www.agner.org/random Randomc
- rngOpenMP
I tried to include the rsprng RNG, but could not manage to use it in my
code.
My conclusions:
- all the implementations work, me...

aligned memory allocation in C
...in C.
Does R_alloc return a pointer to aligned memory?
if not how can I do this?
probably no, because R crashes when I succesively R_alloc and
fill_array32 (cf below) on my macbook with R 2.7.1.
Thanks in advance
Kind regards

Voicemail files permission
I'm using asterisk 1.2.14
When asterisk stores voicemail messages in
/var/spool/asterisk/voicemail/default/EXTENSION/INBOX files are created with:

Asterisk as a stand alone voice mail server
I'm sure asterisk would make a great stand alone voice mail server.
Basically I want to get rid of our voice mail system and replace it with
*, but the problem is we use a cisco cluster with skinny clients. So I
was thinking the way to contact a * server, would be through our 3640.
But so far any attempt has failed. I am wondering if anyone has done
something similar. Just want to verify the
