OpenVMS,
OpenVMS Alpha, (VMS) |
References to OpenVMS (formerly VMS®), and OpenVMS Alpha refer to the OpenVMS Alpha operating system. |
|
Compaq Fortran
(DIGITAL Fortran 90) |
References to Compaq Fortran (formerly DIGITAL Fortran 90) refer to the Compaq Fortran compiler, which fully supports the Fortran 90 and Fortran 95 standards (as well as Compaq Fortran extensions). |
|
Compaq Fortran 77
(DIGITAL Fortran 77) (DEC Fortran) |
The term Compaq Fortran 77 (formerly DEC Fortran and DIGITAL Fortran 77) refers to the Compaq Fortran 77 compiler, which supports the FORTRAN-77 standard (as well as Compaq Fortran 77 extensions). |
In this manual, some version numbers are given as "Vn.n". When you install Compaq Fortran, the actual version numbers appear on your screen.
For this release of Compaq Fortran, Compaq provides two separate compilers (Compaq Fortran and Compaq Fortran 77) under one license and one name (Compaq Fortran). You can choose to install and/or use either compiler or both compilers.
By default, the FORTRAN command invokes the Compaq Fortran compiler, which supports the Fortran 90 and 95 standards as well as older versions of the Fortran language. If you choose to also install the older Compaq Fortran 77 compiler, programmers can request the Compaq Fortran 77 compiler by using the /OLD_F77 qualifier on the FORTRAN command line.
You can install the Compaq Extended Math Library (CXML) separately from Compaq Fortran, which allows you to call the CXML routines from either Compaq Fortran or Compaq Fortran 77.
You can install CXML either before or after you install Compaq Fortran. When installing Compaq Fortran, you must install the Compaq Fortran Run-Time Library (RTL) before Compaq Fortran (see Chapter 2).
Before starting the installation procedure in Chapter 2, you should complete the preparations explained in this chapter. This chapter includes the following sections:
The OpenVMS Alpha Software Product Library CD-ROM (media CD-ROM) set provides the following files:
To determine whether the appropriate media CD-ROM is already mounted on your system, contact the appropriate system manager.
Compaq Fortran provides online release notes and an online "read first" cover letter:
For information about using the CDMENU utility and locating the appropriate media CD-ROM and directory that contains the Compaq Fortran cover letter, see the first few steps in Chapter 2.
Once the appropriate media CD-ROM has been mounted and the appropriate Compaq Fortran documentation directory located, do one of the following:
For information about reading the online release notes before installation, use the PRODUCT EXTRACT RELEASE_NOTES command described in Section 2.1 (step 6).
Compaq strongly recommends that you read the release notes and the cover letter before installing Compaq Fortran. They contain information about changes to the installation and use of Compaq Fortran, such as the minimum version of the OpenVMS Alpha operating system required for this release of Compaq Fortran.
After Compaq Fortran installation, the release notes are installed in:
SYS$HELP:FORTRAN.RELEASE_NOTES |
The release notes are also provided in PostScript form after installation in the following file:
SYS$HELP:FORTRAN_RELEASE_NOTES.PS |
Release notes for CXML are provided separately. After installing CXML, the CXML release notes are installed in:
SYS$HELP:CXML-*NOTES.TXT |
The CXML release notes and the CXML Reference Guide are also provided
in PostScript form in the SYS$HELP directory.
1.2 Required Operating System Components
Compaq Fortran Version 7.3 requires the OpenVMS Alpha operating system Version 7.1 or higher.
Future Compaq Fortran releases may require higher versions of the operating system, as described in the online release notes or the Read Before Installing or Using Compaq Fortran Version n.n for OpenVMS Alpha Systems (cover) letter.
The OpenVMS Alpha operating system comes with a variety of support options (or components). To use Compaq Fortran, your system should be running a version of the OpenVMS Alpha operating system that includes the base component and the following other components:
For a complete list of the required components, see Compaq Fortran
Software Product Description (SPD) on the media CD-ROM.
1.3 License Registration
Before you install and run Compaq Fortran Version 7.3 on a newly-licensed node (or cluster), you must first register a License Product Authorization Key (License PAK), using the License Management Facility (LMF). CXML does not require a License PAK. The specific LMF product names used by Compaq Fortran are listed in Table 1-1:
| LMF Product Name | Use |
|---|---|
|
FORTRAN
FORTRAN90 |
Unlimited or Personal-Use License |
|
FORTRAN-USER
FORTRAN90-USER |
Concurrent-Use License |
The Compaq Fortran and Compaq Fortran 77 compilers will each accept either a FORTRAN(-USER) or FORTRAN90(-USER) PAK. It is not required that PAKs for both product names of a given license type be loaded.
The License PAK may be shipped along with the kit if you ordered the license and media together; otherwise, it is shipped separately to a location based on your license order. If you are installing Compaq Fortran as an update on a node or cluster already licensed for this software, you have already completed the License PAK registration requirements.
If you are installing prerequisite or optional software along with Compaq Fortran, review the PAK status and install the PAKs for any prerequisite or optional software before you install Compaq Fortran.
You must register and load your license for Compaq Fortran before you start the installation in order to run the Installation Verification Procedure (IVP) and use the software.
Log in to a privileged account, such as the system manager's account, SYSTEM. You have a choice of two ways to register a license:
If you plan to use Compaq Fortran on more than one node in a cluster, you will need to perform a license load on the other nodes after you complete this installation. See Section 3.3.
For complete information on using LMF, see the OpenVMS License Management Utility Manual.
1.4 Installation Procedure Requirements
After you have registered and loaded the license PAK and have
previously read the appropriate parts of this installation guide, the
installation takes approximately 2 to 5 minutes, depending on your
system configuration.
1.4.1 Installation Account Privileges and Disk Space
To install Compaq Fortran or CXML, you must be logged in to an account that has at least the following privileges enabled:
Table 1-2 lists Compaq Fortran's requirements for free disk storage space.
| Kit Component | During Installation | After Installation |
|---|---|---|
| Compaq Fortran Compiler | 25,000 blocks | 25,000 blocks |
| Compaq Fortran 77 Compiler | 12,000 blocks | 12,000 blocks |
| Compaq Fortran Run-Time Library | 10,000 blocks | 200 blocks |
| Compaq Fortran Complete kit | 47,000 blocks | 37,200 blocks |
| Compaq Extended Math Library (optional) | 150,000 blocks | 150,000 blocks |
To determine the number of free disk blocks on the current system disk, enter the following DCL command:
$ SHOW DEVICE SYS$SYSDEVICE |
For information on installing 64-bit tools support, see Section 2.3.
1.4.2 System Parameters
Installing Compaq Fortran (both compilers) requires certain system parameter settings.
The minimum number of free global pagelets (512-byte subpage unit) and global sections needed is eleven (11) global sections and approximately 20,000 contiguous free global pagelets, plus a sufficient number of contiguous free global pagelets to contain the file SYS$LIBRARY:DCLTABLES.EXE (see Section 1.4.2.1).
If the optional Compaq Extended Math Library is installed, an additional 18 global sections and 50,000 contiguous free global pagelets are required.
These values represent the number of free global pagelets and global sections required for the installation, not the total number you need to run your system and other software.
If you do not ensure that your system has the necessary global pagelets and global section SYSGEN parameters for the installation, the DCL tables can become corrupted in some situations. |
To install and run Compaq Fortran, you must have sufficient free global pagelets and global sections.
Enter the following DCL command to determine the number of global pagelets required by SYS$LIBRARY:DCLTABLES.EXE:
$ DIRECTORY/SIZE SYS$LIBRARY:DCLTABLES.EXE |
This command returns the size (in blocks) of SYS$LIBRARY:DCLTABLES.EXE. As an approximation, use this figure as the number of global pagelets for the file.
You can use the WRITE command with the F$GETSYI lexical function to find the number of free contiguous global pagelets and free global sections. The following example shows how to get this information at your terminal (the default for SYS$OUTPUT):
$ WRITE SYS$OUTPUT F$GETSYI("CONTIG_GBLPAGES")
15848
$ WRITE SYS$OUTPUT F$GETSYI("FREE_GBLSECTS")
24
|
If the value of free global pagelets or global sections is less than the required value (see Section 1.4.2), you must increase the system parameter setting.
Section 1.4.2.2 describes the procedures for increasing these values using
AUTOGEN.
1.4.2.2 Changing System Parameter Values with AUTOGEN
If you do not have enough free global pagelets or free global sections to install Compaq Fortran, you can use the AUTOGEN command procedure to increase the GBLPAGES or GBLSECTIONS system parameters.
AUTOGEN automatically adjusts values for parameters that are associated with the values you reset manually. To change system parameters with AUTOGEN, edit the following file:
SYS$SYSTEM:MODPARAMS.DAT |
To change a parameter value listed in this file, delete the current value associated with that parameter and enter the new value.
To add a new parameter, add a line to the file that specifies the name of the parameter and its value. To modify incremental parameters such as GBLPAGES and GBLSECTIONS, use the ADD_ prefix.
After you make all your changes, exit from the editor.
When you execute the AUTOGEN procedure to recalculate your system parameters, AUTOGEN uses the information in your MODPARAMS.DAT file and also can automatically adjust some of the SYSGEN parameters based on the consumption of resources since the last reboot.
For information about using AUTOGEN and its command-line parameters,
see the OpenVMS System Manager's Manual: Tuning, Monitoring, and Complex Systems.
1.5 Backing Up Your System Disk
Compaq recommends that you do a system disk backup before installing
any software. Use the backup procedures that are established at your
site. For details on performing a system disk backup, see the
Using VMS BACKUP manual.
1.6 Recovering from Installation Errors
Errors can occur during the installation if any of the following conditions exist:
For descriptions of error messages generated by these and related conditions, see the OpenVMS Alpha documentation on system messages and software installation or the online HELP/MESSAGE command. Take the appropriate action described in the message.
For information on system requirements for installing Compaq Fortran, see Section 1.2.
For a list of problems that can cause an unsuccessful installation, see Section 3.9.
To report a problem to Compaq, see Section 3.10.
