Intel® Fortran Compiler 17.0 Developer Guide and Reference
This topic only applies to Intel® Many Integrated Core Architecture (Intel® MIC Architecture).
The Offload Extract tool is a standalone tool that extracts embedded target objects from fat objects and embedded target binaries from fat executables on Windows* and Linux* systems. The tool can be used for Intel® MIC Architecture related offload extraction. For simplicity, in this topic, the Intel® MIC Architecture target objects and executables will be referred to as Intel® MIC target objects and executables.
By default, you cannot use analyzing and debugging tools like objdump and readelf to directly examine offload Intel® MIC objects/binaries because they are embedded in the host object or binary.
Use the Offload Extract tool to extract Intel® MIC object/binary from a fat object/binary on 64-bit Linux* or 64-bit Windows* systems. The extracted object/binary is an ELF object that can be analyzed with objdump or readelf analyzing tools.
To extract the target object files, invoke the offload extract tool as follows:
offload_extract <fat host object>
The Intel® MIC target objects are extracted into object files with the same name as the input object file but with the substring Intel® MIC appended to the filename. Since the target objects are in ELF format the object file name extension will be .o. For example,
offload_extract host.obj => hostMIC.o
To extract the target executables, invoke the offload extract tool as follows:
offload_extract <fat host binary>
TheIntel® MIC target executables are extracted into target executable files with the same name as the input object file but with the file extension Intel® MIC added. For example,
offload_extract host.exe => hostMIC.mic
To extract the target object files from an archived library, you must first extract the individual fat objects from the fat archived library and then invoke the offload extract tool on the individual fat objects. For example:
ar -x libhost.a offload_extract <individual fat host object>
There are two options you can use to fine tune your extraction of offload binaries or executables.
Use the -o option to specify target filename or output directory. The syntax for the option is as follows:
offload_extract <fat host object|binary> [-o <output filename>] offload_extract <fat host object|binary> [–o <output directory>]
When you use the -o option the target output filename and directory are generated without theIntel® MIC substring.
Use the -target option to select specific target Intel® MIC objects/executables to be extracted. The syntax for the option is as follows:
offload_extract <fat host object|binary> [–target mic]
