Running Java Examples

The Java examples support all the C and C++ compilers that Intel MKL does. The makefile intended to run the examples also needs the make utility, which is typically provided with the Linux* OS distribution.

To run Java examples, the JDK* developer toolkit is required for compiling and running Java code. A Java implementation must be installed on the computer or available via the network. You may download the JDK from the vendor website.

The examples should work for all versions of JDK. However, they were tested only with the following Java implementation s for all the supported architectures:

J2SE* SDK 1.4.2, JDK 5.0 and 6.0 from Sun Microsystems, Inc. (http://sun.com/).
JRockit* JDK 1.4.2 and 5.0 from Oracle Corporation (http://oracle.com/).

Note that the Java run-time environment* (JRE*) system, which may be pre-installed on your computer, is not enough. You need the JDK* developer toolkit that supports the following set of tools:

java
javac
javah
javadoc

To make these tools available for the examples makefile, set the JAVA_HOME environment variable and add the JDK binaries directory to the system PATH, for example , using thebash shell:

export JAVA_HOME=/home/<user name>/jdk1.5.0_09

export PATH=${JAVA_HOME}/bin:${PATH}

You may also need to clear the JDK_HOME environment variable, if it is assigned a value:

unset JDK_HOME

To start the examples, use the makefile found in the Intel MKL Java examples directory:

make {soia32|sointel64|libia32|libintel64} [function=...] [compiler=...]

If you type the make command and omit the target (for example, soia32), the makefile prints the help info, which explains the targets and parameters.

For the examples list, see the examples.lst file in the Java examples directory.

Optimization Notice
Intel® compilers, associated libraries and associated development tools may include or utilize options that optimize for instruction sets that are available in both Intel® and non-Intel microprocessors (for example SIMD instruction sets), but do not optimize equally for non-Intel microprocessors. In addition, certain compiler options for Intel compilers, including some that are not specific to Intel micro-architecture, are reserved for Intel microprocessors. For a detailed description of Intel compiler options, including the instruction sets and specific microprocessors they implicate, please refer to the "Intel® Compiler User and Reference Guides" under "Compiler Options". Many library routines that are part of Intel® compiler products are more highly optimized for Intel microprocessors than for other microprocessors. While the compilers and libraries in Intel® compiler products offer optimizations for both Intel and Intel-compatible microprocessors, depending on the options you select, your code and other factors, you likely will get extra performance on Intel microprocessors. Intel® compilers, associated libraries and associated development tools may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include Intel® Streaming SIMD Extensions 2 (Intel® SSE2), Intel® Streaming SIMD Extensions 3 (Intel® SSE3), and Supplemental Streaming SIMD Extensions 3 (Intel® SSSE3) instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. While Intel believes our compilers and libraries are excellent choices to assist in obtaining the best performance on Intel® and non-Intel microprocessors, Intel recommends that you evaluate other compilers and libraries to determine which best meet your requirements. We hope to win your business by striving to offer the best performance of any compiler or library; please let us know if you find we do not. Notice revision #20110307
