NAME
maria - Modular Reachability Analyzer for high-level Petri nets
SYNOPSIS
maria [options] files...
DESCRIPTION
This manual page documents briefly the maria command. More complete documentation is available in the
GNU Info format; see below.
maria is a program that analyzes models of concurrent systems, described in its input language that is
based on Algebraic System Nets. The formalism was presented by Ekkart Kindler and Hagen Völzer at
ICATPN'98, Flexibility in Algebraic Nets.
Algebraic System Nets is a framework that does not define any data types or algebraic operations. The
data type system and the operations in Maria are designed with high-level programming and specification
languages in mind. Despite that, each Maria model has a finite unfolding.
To ensure interoperability with low-level Petri net tools, Maria translates identifiers in unfolded nets
to strings of alpha-numerical characters and underscores. The filter foldname.pl can be used or adapted
to improve the readability of the identifiers.
OPTIONS
Maria follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A
summary of options is included below. For a complete description, see the Info files.
-a limit, --array-limit=limit
Limit the size of array index types to limit possible values. A limit of 0 disables the checks.
-b model, --breadth-first-search=model
Generate the reachability graph of model using breadth-first search.
-C directory, --compile=directory
Generate C code in directory for evaluating expressions and for the low-level routines of the
transition instance analysis algorithm. When this option is used, evaluation errors are reported
in a slightly different way. The interpreter displays the valuation and expression that caused
the first error in a state; the compiled code displays the number of errors. For performance
reasons, the generated code does not check for overflow errors when adding items to multi-sets.
-c, --no-compile
The opposite of -C. Evaluate all expressions in the built-in interpreter. This is the default
behavior.
-D symbol, --define=symbol
Define the preprocessor symbol symbol.
-d model, --depth-first-search=model
Generate the reachability graph of model using depth-first search.
-E interval, --edges=interval
When generating the reachability graph, report the size of the graph after every interval
generated edges.
-e string, --execute=string
Execute string.
-g graphfile, --graph=graphfile
Load a previously generated reachability graph from graphfile.rgh.
-H h[,f[,t]], --hashes=h[,f[,t]]
Configure the parameters for probabilistic verification (-P). Allocate t universal hash functions
of f elements and corresponding hash tables of h bits each. Both h and f will be rounded up to
next suitable values.
-?, -h, --help
Print a summary of the command-line options to Maria and exit.
-I directory, --include=directory
Append directory to the list of directories searched for include files.
-i columns, --width=columns
Set the right margin of the output to columns. The default is 80.
-j processes, --jobs=processes
When checking safety properties (options -L, -M and -P), use this many worker processes to speed
up the analysis on a multiprocessor computer. See also -k and -Z.
-k port[/host], --connect=port[/host]
Distribute safety model checking (options -L, -M and -P) in a TCP/IP network. For the server,
only port is specified as a 16-bit unsigned integer, usually between 1024 and 65535. For the
worker processes, port/host specifies the port and the address of the server. See also -j.
-L model, --lossless=model
Load model and prepare for analyzing it by constructing a set of reachable states in disk files.
See also -M, -P, -j and -k.
-m model, --model=model
Load model and clear its reachability graph.
-M model, --md5-compacted=model
Load model and prepare for analyzing it by constructing an over-approximation of set of reachable
states in the main memory. See also -P, -L, -j and -k.
-N cregexp, --name=cregexp
Specify the names allowed in context c as the extended regular expression regexp. The context is
identified by the first character of the parameter string; the succeeding characters constitute
the regular expression that allowed names must match.
-n cregexp, --no-name=cregexp
Specify the names not allowed in context c as the extended regular expression regexp.
If both -N and and -n are specified for a context c, then the allowing match takes precedence.
For instance, to require that all user defined type names be terminated with _t, specify -nt
-Nt'_t$'. The quotes in the latter parameter are required to remove the special meaning from $ in
the command line shell you are probably using to invoke Maria.
-P model, --probabilistic=model
Load model and prepare for analyzing it by constructing a set of reachable states in the main
memory by using a technique called bitstate hashing.
-p command, --property-translator=command
Specify the command to use for translating property automata. The command should read a formula
from the standard input and write a corresponding automaton description to the standard output.
The translator lbt is compatible with this option.
-q limit, --quantification-limit=limit
Prevent quantification (multi-set sum) of types having more than limit possible values. A limit
of 0 disables the checks.
-U symbol, --undefine=symbol
Undefine the preprocessor symbol symbol.
-u [a][f[outfile]], --unfold=[a][f[outfile]]
Unfold the net using algorithm a and write it in format f to outfile. If outfile is not
specified, dump the unfolded net to the standard output. Possible formats are m (Maria (human-
readable), default), l (LoLA), p (PEP), and r (PROD). There are two algorithms: traditional
(default) and reduced by constructing a coverable marking (M).
-V, --version
Print the version number of Maria and exit.
-v, --verbose
Display verbose information on different stages of the analysis.
-W, --warnings
Enable warnings about suspicious net constructs. This is the default behavior.
-w, --no-warnings
The opposite of -W. Disable all warnings.
-x numberbase, --radix=numberbase
Specify the number base for diagnostic output. Allowed values for numberbase are oct, octal, 8,
hex, hexadecimal, 16, dec, decimal and 10. The default is to use decimal numbers.
-Y, --compress-hidden
Reduce the set of reachable states by not storing the successor states of transitions instances
for which a hide condition holds. The hidden successors are stored to a separate state set. This
option may save memory (-L or -m) or reduce the probability that states are omitted (-M or -P),
and it may improve the efficiency of parallel analysis (-j or -k), but it may also considerably
increase the processor time requirement. The option also works with liveness model checking, but
there is no guarantee that the truth values of liveness properties remain unchanged. This option
can be combined with -Z.
-y, --no-compress-hidden
The opposite of -Y. This is the default behavior.
-Z, --compress-paths
Reduce the set of reachable states by not storing intermediate states that have at most one
successor. This option may save memory (-L or -m) or reduce the probability that states are
omitted (-M or -P), and it may improve the efficiency of parallel analysis (-j or -k), but it may
also considerably increase the processor time requirement. The option also works with liveness
model checking, but there is no guarantee that the truth values of liveness properties remain
unchanged. This option can be combined with -Y.
-z, --no-compress-paths
The opposite of -Z. This is the default behavior.
