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. !</PRE> !</DESCRIPTION> USE module_internal_header_util USE module_timing INTEGER, PARAMETER :: int_num_handles = 99 INTEGER, PARAMETER :: max_servers = int_num_handles+1 ! why +1?

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: !

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.
