SHOW SHARED MEMORY INTERFACES

Syntax:

SHOW [SHARED] MEMORY [INTERFACE[S]] <program> [ ,<program> ]...

Function:

This command shows the variables which are used to transfer data into and out of the named programs through shared memory.

FPT is run on a suite of programs which share COMMON blocks. Read and write access to the variables in the COMMON blocks is analysed, and the flow of data is reported. FPT takes EQUIVALENCE relationships into account when making the analysis.

Where to use this command:

Operating system command line	Yes
Configuration file, config.fsp	Yes
Specification (FSP) files, *.fsp	Yes
Interactively, to FPT> prompt:	Yes
Interactive command files	Yes
Embedded in the Fortran code	No

Example:

FPT is used to analyse a suite of programs which share COMMON blocks through reflective memory. The command:

FPT> show shared memory datlog

generates the report:
