ALPHABET-GRID(1)					      ALPHABET-GRID(1)

NAME
       grid - peer-to-peer data distribution

SYNOPSIS
       load alphabet
       typeset /grid
       type /grid/endpoint

DESCRIPTION
       Grid  is	 a  typeset  for  alphabet  (see sh-alphabet(1)) which enables
       allows direct interconnection of remote	and  local  processing	compo‐
       nents.  It  defines one new type, endpoint, which represents a place in
       the network to which two parties can connect and exchange data.

       In the following descriptions, if a type is  not	 endpoint  or  a  type
       defined in the root typeset (see alphabet-main(1)), it is assumed to be
       of type /string.

       Modules currently provided within the /grid typeset include:

       farm [-lnkavA] endpoint addr tasktype [arg...] -> endpoint
		 Farm connects to a grid labour exchange (see scheduler(4)) at
		 addr,	starts	a new job of type workflow, and passes all the
		 data read from endpoint to  be	 processed  by	the  currently
		 available  labour.   The data is split into records, each one
		 of which will be processed on a worker node by tasktype, with
		 its  associated  arguments.   Other  than -A, which specifies
		 unauthenticated access to the scheduler, the various  options
		 are  all  passed  verbatim to workflow: -l causes it to split
		 its input on newline-separated records; -n specifies that  no
		 record	 separation  is necessary on output; -k specifies that
		 intermediate data for failed tasks should be kept around;  -a
		 specifies that intermediate data for all tasks should be kept
		 around, and -v specifies that workflow should produce a wordy
		 description of what it is doing.

       local endpoint -> /fd
		 Local reads everything from endpoint, and writes it to fd.

       remote [-a addr] fd -> endpoint
		 Remote	 is  the  inverse  of local: it reads data from fd and
		 writes it to a newly created endpoint.	 If -a is given,  addr
		 specifies  the network address of an endpoint server on which
		 to create the new endpoint.

       rexec [-A] endpoint addr cmd -> endpoint
		 Rexec connects to a remote execution server  at  addr	(unau‐
		 thenticated  if -A is specified), and arranges to execute the
		 alphabet expression cmd there. The expression should be  com‐
		 patible with usage fd -> fd.  Data from the argument endpoint
		 will be piped through this expression, and made available  as
		 the resulting endpoint endpoint.

EXAMPLES
       The  examples below that a local endpoint is available, and the follow‐
       ing alphabet declarations:
	    load alphabet
	    typeset /grid
	    type /string /endpoint /fd
	    import /grid/local /grid/remote
	    autoconvert fd endpoint remote
       Set up a rendering pipeline:
	    -{/read /tmp/somedata |
		 remote |
		 rexec tcp!node1!rexec "{(/fd); /filter $1 "{os render_stage1}} |
		 rexec tcp!node2!rexec "{(/fd); /filter $1 "{os render_stage2}} |
		 /create /tmp/somedata.result
	    }
