The NETWORK Procedure

specifies whether to enforce determinism. By default, DETERMINISTIC=TRUE, which ensures that each invocation (with the same machine configuration and parameter settings) produces the same final result. For more information about determinism, see the section Determinism.

specifies whether the input graph should be considered directed or undirected. You can specify the following values:

By default, DIRECTION=UNDIRECTED. For more information, see the section Graph Input and Output Data.

specifies whether to use a distributed graph. By default, DISTRIBUTED=FALSE, which means that a distributed graph is not used. For more information about the algorithms that support distributed graph computation, see the section Execution Modes and Data Movement.

specifies the in-memory graph to use. This option can be used with any algorithm that supports in-memory execution.

For more information about using the GRAPH= option, see the section Persistent Data Structures (In-Memory Graphs).

specifies the index offset for identifiers in the log and results output data tables. For example, if three cycles are found in cycle enumeration, they are labeled cycles 1, 2, and 3 by default. If INDEXOFFSET=4, they are labeled cycles 4, 5, and 6. The value of number must be an integer greater than or equal to 0. By default, INDEXOFFSET=1.

specifies the input data table that contains the graph link information. CAS-libref.data-table is a two-level name, where CAS-libref refers to the caslib and session identifier, and data-table specifies the name of the input data table. For more information about this two-level name, see the section Using CAS Sessions and CAS Engine Librefs in Chapter 1, Introduction.

For more information about this input table, see the section Links Input Data.

specifies the input data table that contains the graph link information for the query graph. CAS-libref.data-table is a two-level name, where CAS-libref refers to the caslib and session identifier, and data-table specifies the name of the input data table. For more information about this two-level name, see the section Using CAS Sessions and CAS Engine Librefs in Chapter 1, Introduction.

This option is supported only when used in conjunction with the PATTERNMATCH statement. For more information about this input table, see the section Pattern Matching.

controls the frequency (in number of seconds) for displaying iteration logs for some algorithms, where number can be any integer greater than or equal to 1. This option is useful for computationally intensive algorithms. Setting number too low can hurt algorithm performance. This option is ignored for a single-server setup. By default, LOGFREQTIME=5.

controls the amount of information that is displayed in the SAS log. You can specify the following values:

By default, LOGLEVEL=BASIC.

specifies whether to include or aggregate multilinks when an input graph (specified by the LINKS= or LINKSQUERY= option) is read. You can specify the following values:

By default, MULTILINKS=TRUE for algorithms that support multilinks.

For more information about this option, see the section Multigraphs.

specifies the input data table that contains the graph node information. CAS-libref.data-table is a two-level name, where CAS-libref refers to the caslib and session identifier, and data-table specifies the name of the input data table. For more information about this two-level name, see the section Using CAS Sessions and CAS Engine Librefs in Chapter 1, Introduction.

For more information about this input table, see the section Nodes Input Data.

specifies the input data table that contains the graph node information for the query graph. CAS-libref.data-table is a two-level name, where CAS-libref refers to the caslib and session identifier, and data-table specifies the name of the input data table. For more information about this two-level name, see the section Using CAS Sessions and CAS Engine Librefs in Chapter 1, Introduction.

This option is supported only when used in conjunction with the PATTERNMATCH statement. For more information about this input table, see the section Pattern Matching.

specifies the input data table that contains the graph node subset information. CAS-libref.data-table is a two-level name, where CAS-libref refers to the caslib and session identifier, and data-table specifies the name of the input data table. For more information about this two-level name, see the section Using CAS Sessions and CAS Engine Librefs in Chapter 1, Introduction.

For more information about this input table, see the section Nodes Subset Input Data.

specifies the maximum number of threads to use for multithreaded processing. Some of the algorithms can take advantage of multicore machines and can run faster when number is greater than 1 (see Table 6 for a list). Algorithms that cannot take advantage of this option use only one thread even if number is greater than 1. For distributed execution, number specifies the maximum number of threads to use on each machine. The value of number can be any integer between 1 and 1024, inclusive. The default is the number of cores on the machine that executes the process or the number of cores permissible based on your installation (whichever is less). The number of simultaneously active CPUs is limited by your installation and license configuration.

specifies the output data table to contain summary information about in-memory graphs. CAS-libref.data-table is a two-level name, where CAS-libref refers to the caslib and session identifier, and data-table specifies the name of the output data table. For more information about this two-level name, see the section Using CAS Sessions and CAS Engine Librefs in Chapter 1, Introduction.

specifies the output data table to contain the graph link information along with any results from the algorithms that calculate metrics on links. CAS-libref.data-table is a two-level name, where CAS-libref refers to the caslib and session identifier, and data-table specifies the name of the output data table. For more information about this two-level name, see the section Using CAS Sessions and CAS Engine Librefs in Chapter 1, Introduction.
