Copy the tar file to a directory with write access and change to that directory.
cd

Extract the files and executable from the tar file with the following command:
tar -xzvf ESSL-4.4.1-1.tar.gz

Change directory to the correct operating system (that is, SLES).

Type the following command and then press Enter.

ON SLES10:
./installptf_essl4411 [-d rpmpath] [-links43 | -links44]

ON SLES11:
./installptf_essl4411 [-d rpmpath]

ON RHEL5:
./installptf_essl4411 [-d rpmpath] [-links43 | -links44] [-selinux | -noselinux]

where:

OPTIONAL:
-d RPMPATH specifies the full path to the directory that contains the ESSL Version 4.4.1 RPMs. If not specified, it is assumed that ESSL 4.4.1-1 RPMs are located in the current working directory.

[-links43 | -links44 ]
-links43
Indicates that, if ESSL 4.3.x is already installed, you would like to select ESSL 4.3.x as your default environment.

-links43
Indicates that you would like to select ESSL 4.4.x as your default environment-links43

For more information, see Appendix B, "Maintaining both ESSL 4.3.x and ESSL 4.4 on SLES10 (non Blue Gene users only) or RHEL5", in the ESSL for Linux on POWER, Version 4 Release 4.1 Installation Guide.

[-selinux | -noselinux]
is an optional flag (available only on RHEL5) indicating whether or not you want the installation script to add the required permissions to the default RHEL5 Security Enhanced Linux (SELinux) policy, so that SELinux will allow the ESSL 64-bit libraries to be loaded.

Note: If SELinux has been enabled on your RHEL5 system and you do not specify either -selinux or -noselinux when you upgrade ESSL, the permissions will be added by default.

-selinux indicates that you want the installation script to add the required permissions to the default SELinux policy. This is the default value (if SELinux has been enabled on your RHEL5 system).

-noselinux indicates that you do not want the installation script to add the required permissions to the default SELinux policy.

For more information, see Appendix C, "Configuring RHEL5 SELinux to allow ESSL 64-bit libraries to load," in the ESSL for Linux on POWER, Version 4 Release 4.1 Installation Guide.

The installptf_essl script is the preferred way of installing this update. However, the RPMs may be installed manually using the following commands:

rpm -e --nodeps essl.common-4.4.1
rpm -e --nodeps essl.rte-4.4.1
rpm -ivh essl.common-4.4.1-1.ppc64.rpm
rpm -ivh essl.rte-4.4.1-1.ppc64.rpm

Note: If the ESSL product is not installed in the default directory of /opt/ibmmath, then you must specify the directory using the --prefix parameter on the "rpm -ivh" command.

Example:
rpm -ivh essl.common-4.4.1-1.ppc64.rpm --prefix=essl_path

For additional information, refer to the ESSL for Linux on POWER, Version 4 Release 4.1 Installation Guide.

ESSL performs computations using high-performance algorithms.

ESSL provides these run-time libraries:

ESSL Symmetric Multi-Processing (SMP) Library
ESSL Serial Library

How to build C or C++ programs that call ESSL if you only have the XL Fortran run-time environment installed instead of the XL Fortran compiler.

After you install the XL Fortran run time environment, run the esslxlfrtelnk script once to set up the required symbolic links to the Fortran libraries. Copy the sample esslxlfrtelnk script provided on this page.

To execute issue:

dos2unix esslxlfrtelnk
esslxlfrtelnk
