A metatable can be defined like

local t = setmetatable({}, {
  __tostring = function() return 'custom tostring behavior!' end
})

Here are the metamethods that you can define, and their behavior

Operators

-- split a string
function string:split(delimiter)
  local result = { }
  local from  = 1
  local delim_from, delim_to = string.find( self, delimiter, from  )
  while delim_from do
    table.insert( result, string.sub( self, from , delim_from-1 ) )
    from  = delim_to + 1
    delim_from, delim_to = string.find( self, delimiter, from  )

Demo of how to pass GPU memory managed by pycuda to mpi4py.

Notes
-----
This code can be used to perform peer-to-peer communication of data via
NVIDIA's GPUDirect technology if mpi4py has been built against a
CUDA-enabled MPI implementation.
