MODULE module_wrf_quilt 
(docs) 19
!<DESCRIPTION>
!<PRE>
! This module contains WRF-specific I/O quilt routines called by both
! client (compute) and server (I/O quilt) tasks. I/O quilt servers are
! a run-time optimization that allow I/O operations, executed on the I/O
! quilt server tasks, to be overlapped with useful computation, executed on
! the compute tasks. Since I/O operations are often quite slow compared to
! computation, this performance optimization can increase parallel
! efficiency.
!
! Currently, one group of I/O servers can be specified at run-time. Namelist
! variable "nio_tasks_per_group" is used to specify the number of I/O server
! tasks in this group. In most cases, parallel efficiency is optimized when
! the minimum number of I/O server tasks are used. If memory needed to cache
! I/O operations fits on a single processor, then set nio_tasks_per_group=1.
! If not, increase the number of I/O server tasks until I/O operations fit in
! memory. In the future, multiple groups of I/O server tasks will be
! supported. The number of groups will be specified by namelist variable
! "nio_groups". For now, nio_groups must be set to 1. Currently, I/O servers
! only support overlap of output operations with computation. Also, only I/O
! packages that do no support native parallel I/O may be used with I/O server
! tasks. This excludes PHDF5 and MCEL.
!
! In this module, the I/O quilt server tasks call package-dependent
! WRF-specific I/O interfaces to perform I/O operations requested by the
! client (compute) tasks. All of these calls occur inside subroutine
! quilt().
!
! The client (compute) tasks call package-independent WRF-specific "quilt I/O"
! interfaces that send requests to the I/O quilt servers. All of these calls
! are made from module_io.F.
!
! These routines have the same names and (roughly) the same arguments as those
! specified in the WRF I/O API except that:
! - "Quilt I/O" routines defined in this file and called by routines in
! module_io.F have the "wrf_quilt_" prefix.
! - Package-dependent routines called from routines in this file are defined
! in the external I/O packages and have the "ext_" prefix.
!
! Both client (compute) and server tasks call routine init_module_wrf_quilt()
! which then calls setup_quilt_servers() determine which tasks are compute
! tasks and which are server tasks. Before the end of init_module_wrf_quilt()
! server tasks call routine quilt() and remain there for the rest of the model
! run. Compute tasks return from init_module_wrf_quilt() to perform model
! computations.
!
! See http://www.mmm.ucar.edu/wrf/WG2/software_2.0/IOAPI.doc for the latest
! version of the WRF I/O API. This document includes detailed descriptions
! of subroutines and their arguments that are not duplicated here.

!<DESCRIPTION>
! Both client (compute) and server tasks call this routine to
! determine which tasks are compute tasks and which are I/O server tasks.
!
! Module variables MPI_COMM_LOCAL and MPI_COMM_IO_GROUPS(:) are set up to
! contain MPI communicators as follows:
!
! MPI_COMM_LOCAL is the Communicator for the local groups of tasks. For the
! compute tasks it is the group of compute tasks; for a server group it the
! communicator of tasks in the server group.
!
! Elements of MPI_COMM_IO_GROUPS are communicators that each contain one or
! more compute tasks and a single I/O server assigned to those compute tasks.
! The I/O server tasks is always the last task in these communicators.
! On a compute task, which has a single associate in each of the server
! groups, MPI_COMM_IO_GROUPS is treated as an array; each element corresponds
! to a different server group.
! On a server task only the first element of MPI_COMM_IO_GROUPS is used
! because each server task is part of only one io_group.
!
! I/O server tasks in each I/O server group are divided among compute tasks as
! evenly as possible.
!
! When multiple I/O server groups are used, each must have the same number of
! tasks. When the total number of extra I/O tasks does not divide evenly by
! the number of io server groups requested, the remainder tasks are not used
! (wasted).
!
! For example, communicator membership for 18 tasks with nio_groups=2 and
! nio_tasks_per_group=3 is shown below:
!
!<PRE>
! Membership for MPI_COMM_LOCAL communicators:
! COMPUTE TASKS: 0 1 2 3 4 5 6 7 8 9 10 11

! 2ND I/O SERVER GROUP: 15 16 17

! This logic and the logic in the loop below is used to determine whether
! to send a noop records sent by the compute processes to allow to go
! through. The purpose is to make sure that the communications between this
! server and the other servers in this quilt group stay synchronized in
! the collection loop below, even when the servers are serving different
! numbers of clients. Here are some conditions:
!
! 1. The number of compute clients served will not differ by more than 1
! 2. The servers with +1 number of compute clients begin with task 0
! of mpi_comm_local, the commicator shared by this group of servers
!
! 3. For each collective field or metadata output from the compute tasks,
! there will be one record sent to the associated i/o server task. The
! i/o server task collects these records and stores them contiguously
! in a buffer (obuf) using collect_on_comm above. Thus, obuf on this
! server task will contain one record from each associated compute
! task, in order.
!
! 4. In the case of replicated output from the compute tasks
! (e.g. put_dom_ti records and control records like
! open_for_write_commit type records), compute task 0 is the only
! one that sends the record. The other compute tasks send noop
! records. Thus, obuf on server task zero will contain the output
! record from task 0 followed by noop records from the rest of the
! compute tasks associated with task 0. Obuf on the other server
! tasks will contain nothing but noop records.
!
! 5. The logic below will not allow any noop records from server task 0.
! It allows only one noop record from each of the other server tasks
! in the i/o group. This way, for replicated output, when the records
! are collected on one server task below, using collect_on_comm on
! mpi_comm_local, each task will provide exactly one record for each
! call to collect_on_comm: 1 bona fide output record from server task
! 0 and noops from the rest.

! int_local_output_buffer to their I/O quilt server. This communication is
! done in subroutine send_to_io_quilt_servers(). After the I/O quilt servers
! receive this data, they will write all accumulated fields to disk.
!
! Significant time may be required for the I/O quilt servers to organize
! fields and write them to disk. Therefore, the "iosync" request should be
! sent only when the compute tasks are ready to run for a while without
! needing to communicate with the servers. Otherwise, the compute tasks
! will end up waiting for the servers to finish writing to disk, thus wasting

! During a "training" write this routine accumulates number and sizes of

! (client) task.
!
! During a "real" write, this routine begins by allocating
! int_local_output_buffer if it has not already been allocated. Sizes
! accumulated during "training" are used to determine how big
! int_local_output_buffer must be. This routine then stores "int_field"
! headers and associated field data in int_local_output_buffer. The contents
! of int_local_output_buffer are actually sent to the I/O quilt server in
! routine wrf_quilt_iosync(). This scheme allows output of multiple variables
! to be aggregated into a single "iosync" operation.
! This routine is called only by client (compute) tasks.
