If you have installed multicore (for unix/mac), you can find the
number of cores by /*multicore:::detectCores()*/

In windows try this:
Sys.getenv('NUMBER_OF_PROCESSORS')

If no-one replies with a better way, here's a way: under
POSIX-compliant systems, you can write a small C function and wrap it
in an R function.
The C program would be something like
#include
void nProcessors(int & n)
{
#ifdef _SC_NPROCESSORS_ONLN
long nProcessorsOnline = sysconf(_SC_NPROCESSO
windows and ubuntu linux are my OS
intent is to use them in the snow makecluster statement so I am not sure
what I need cores,cpus,real,virtual
basically the max amount of clusters i can create on my machine
2) if I have a workgroup on windows - can i detect cores/cpus on the network
using the d
Without knowing your OS, there is no way anyone can tell you. And you
probably want to know 'cores' rather than CPUs. And for some specific
OSes, you will find answers in the archives.
Beware that this is not a well-defined question: are these
physical or virtual cores?, and having them in th

Sorry if this question seems very basic.
Is there a function to pro grammatically find number of processors in
my system _ I want to pass this as a parameter to snow in some serial
code to parallel code functions
