#-------------------  BIRCH PLATFORM -----------------------
# This section provides several alternative ways for 
# setting $BIRCH_PLATFORM, which tells the os-hardware
# combination for the system to which you are currently
# logged in. 
#


    #Method 1: automatic detection of the platform 
    #If possible, use this method

    #Find out the following platform parameters:
    #  operating system
    #  processor family

    #Operating system
#   set OS = `uname -s`
#   switch ($OS)
#      case SunOS:   
#       set OS = solaris
#       breaksw
#     case linux:  
#      set OS = linux
#       breaksw
#     case Darwin:  
#      set OS = Darwin
#       breaksw
#    default
#      set OS = linux  
#      breaksw 
#   endsw

    #Processor family
#   set PROC = `uname -p`
#   switch ($PROC)
#      case sparc:
#       set PROC = sparc
#   	breaksw
#     case i686:
#      set PROC = intel
#       breaksw
#     case i386:
#      set PROC = intel
#       breaksw
#     case i86pc:
#      set PROC = intel
#       breaksw
#     case x86_64:
#      set PROC = x86_64
#       breaksw
#     case arm64 | aarch64:
#      set PROC = arm64
#       breaksw
#    default
#      set PROC = intel 
#      breaksw 
#   endsw


   # Map the result to supported BIRCH platforms
#   if ($OS == solaris) then
#      switch ($PROC)
#   	case sparc:
#   	  setenv BIRCH_PLATFORM 'solaris-sparc'
#   	  breaksw
#   	case intel:
#   	 setenv BIRCH_PLATFORM 'solaris-amd64'
#   	 breaksw
#       default
#   	 setenv BIRCH_PLATFORM 'solaris-sparc' 
#   	 breaksw 
#      endsw
#      else
#         if ($OS == linux) then
#   	 switch ($PROC)
#   	   case intel:
#   	    setenv BIRCH_PLATFORM 'linux-intel'
#   	     breaksw
#   	   case x86_64:
#   	    setenv BIRCH_PLATFORM 'linux-x86_64'
#   	     breaksw
#   	  default
#   	    setenv BIRCH_PLATFORM 'linux-x86_64' 
#   	    breaksw 
#   	 endsw
#        endif
#      else
#         if ($OS == Darwin) then
#   	 switch ($PROC)
#   	   case intel:
#   	    setenv BIRCH_PLATFORM 'osx-x86_64'
#   	     breaksw
#   	   case arm64 | aarch64:
#   	    setenv BIRCH_PLATFORM 'macos-arm64'
#   	     breaksw
#   	   case x86_64:

#   	 endsw
#        endif
#      else
#         setenv BIRCH_PLATFORM 'linux-intel'  
#      endif


   # Method 2: single platform. This will work if you only
   # run BIRCH on one platform.
   # Uncomment a line if you only use a single platform
   #setenv BIRCH_PLATFORM linux-intel
   #setenv BIRCH_PLATFORM linux-x86_64
   #setenv BIRCH_PLATFORM linux-arm64

   #setenv BIRCH_PLATFORM macos-arm64
   #setenv BIRCH_PLATFORM winxp-32
   #setenv BIRCH_PLATFORM win7-64
   
   # Method 3: determine platform from HOSTNAME
   # This section lets you choose the operating system
   # based on host name. Method 1 is preferable to Method 3.
   # Platform-specific syntax is chosen based on BIRCH_PLATFORM.
   # (default = solaris-amd64)
