ConfigurationProperties

Execution-time parameters supported by JavaCL

There are a few parameters which can be supplied to JavaCL when executing your program. You can specify these either by setting the corresponding Java system properties (the -D argument to the java executable) to true or false or by defining the corresponding environment variables as 0 or 1.

|| Java property || Environment variable || Description || Default || || javacl.cacheBinaries || JAVACL_CACHE_BINARIES || If enabled, JavaCL saves the compiled binaries of the OpenCL programs to a temporary folder, and uses these binaries when the same program is needed in the future, avoiding multiple compilations. || Enabled, except on AMD systems (see Issue 39) || || javacl.adjustDoubleExtension || JAVACL_ADJUST_DOUBLE_EXTENSION || Allows JavaCL to change the double extension used by the kernel between cl_khr_fp64 and cl_amd_fp64 if one is supported and the other is not. || Enabled || || javacl.verbose || JAVACL_VERBOSE || Enables logging of additional messages. If you enable it, you should also enable Java assertions. || Disabled ||

Example:

java -Djavacl.cacheBinaries=false -jar yourprogram.jar

# On Bourne-style shells:
JAVACL_ADJUST_DOUBLE_EXTENSION=0 java -jar yourprogram.jar
# On Windows:
set JAVACL_VERBOSE=1 java -ea -jar yourprogram.jar
