Number of processors

maricanis

Hi,

Is there a way to get number of processors with Ruby in Sketchup.
I've found on internet solutions like this

require 'win32ole'
wmi = WIN32OLE.connect("winmgmts;//")
num = wmi.ExecQuery("select * from Win32_ComputerSystem").NumberOfProcessors

problem is when I run this in Sketchup I get error

- unknown property or method `NumberOfProcessors'
    HRESULT error code;0x80020006
      Unknown name.
Error; #<WIN32OLERuntimeError; unknown property or method `NumberOfProcessors'
    HRESULT error code;0x80020006
      Unknown name.>

I'm using win32ole posted here: [Plugin Library] Win32API and Win32OLE so files

Is this any help?

# Returns the number of processor for Linux, OS X or Windows.
def number_of_processors
  if RUBY_PLATFORM =~ /linux/
    return `cat /proc/cpuinfo | grep processor | wc -l`.to_i
  elsif RUBY_PLATFORM =~ /darwin/
    return `sysctl -n hw.logicalcpu`.to_i
  elsif RUBY_PLATFORM =~ /win32/
    # this works for windows 2000 or greater
    require 'win32ole'
    wmi = WIN32OLE.connect("winmgmts;//")
    wmi.ExecQuery("select * from Win32_ComputerSystem").each do |system| 
      begin
        processors = system.NumberOfLogicalProcessors
      rescue
        processors = 0
      end
      return [system.NumberOfProcessors, processors].max
    end
  end
  raise "can't determine 'number_of_processors' for '#{RUBY_PLATFORM}'"
end

On Windows, an environment var is set for the number of processors:

num = ENV['NUMBER_OF_PROCESSORS'].to_i

num = ENV['NUMBER_OF_PROCESSORS'].to_i is much easier than the other way and should be fine unless you want to have a cross-platform solution... We don't know if MAC has the same ENV variable 0 - some references are similar to PC, while others can be the same ??
