.SH NAME
.LP
\fBmakeflow\fP - workflow engine for executing distributed workflows

.SH SYNOPSIS
.LP
\FC\fBmakeflow [options] <dagfile>\fP\FT

.SH DESCRIPTION
.LP

\fBMakeflow\fP is a workflow engine for distributed computing. It accepts a
specification of a large amount of work to be performed, and runs it on remote
machines in parallel where possible. In addition, \fBMakeflow\fP is
fault-tolerant, so you can use it to coordinate very large tasks that may run
for days or weeks in the face of failures. \fBMakeflow\fP is designed to be
similar to Make, so if you can write a Makefile, then you can write a
\fBMakeflow\fP.

.PP

You can run a \fBMakeflow\fP on your local machine to test it out. If you have
a multi-core machine, then you can run multiple tasks simultaneously. If you
have a Condor pool or a Sun Grid Engine batch system, then you can send your
jobs there to run. If you don't already have a batch system, \fBMakeflow\fP
comes with a system called Work Queue that will let you distribute the load
across any collection of machines, large or small.  \fBMakeflow\fP also
supports execution in a Docker container, regardless of the batch system
used.

.PP

.SH OPTIONS
.LP
When \FCmakeflow\FT is ran without arguments, it will attempt to execute the
workflow specified by the \fBMakeflow\fP dagfile using the \FClocal\FT
execution engine.

.SH DRYRUN MODE
.LP

When the batch system is set to \fB-T\fP <dryrun>, Makeflow runs as usual
but does not actually execute jobs or modify the system. This is useful to
check that wrappers and substitutions are applied as expected. In addition,
Makeflow will write an equivalent shell script to the batch system log
specified by \fB-L\fP <logfile>. This script will run the commands in
serial that Makeflow would have run. This shell script format may be useful
for archival purposes, since it does not depend on Makeflow.

.SH ENVIRONMENT VARIABLES
.LP

The following environment variables will affect the execution of your
\fBMakeflow\fP:
.SS BATCH_OPTIONS
.LP

This corresponds to the \fB-B\fP <options> parameter and will pass extra
batch options to the underlying execution engine.

.SS MAKEFLOW_MAX_LOCAL_JOBS
.LP
This corresponds to the \fB-j\fP <#> parameter and will set the maximum
number of local batch jobs.  If a \fB-j\fP <#> parameter is specified, the
minimum of the argument and the environment variable is used.

.SS MAKEFLOW_MAX_REMOTE_JOBS
.LP
This corresponds to the \fB-J\fP <#> parameter and will set the maximum
number of local batch jobs.  If a \fB-J\fP <#> parameter is specified, the
minimum of the argument and the environment variable is used.
.PP
Note that variables defined in your \fBMakeflow\fP are exported to the
environment.

.SS TCP_LOW_PORT
.LP
Inclusive low port in range used with \FC-p 0\FT.

.SS TCP_HIGH_PORT
.LP)
Inclusive high port in range used with \FC-p 0\FT.

.SH EXIT STATUS
.LP
On success, returns zero.  On failure, returns non-zero.
