Build OpenSSL for Intel Xeon Phi on Windows

Building OpenSSL for Intel Xeon Phi on Windows involves several steps, and it's a complex process. The Xeon Phi architecture is designed for high-performance computing and is typically used with Linux clusters. Building software for Xeon Phi on Windows might require specific toolchains and configurations. Below is a general outline of the process, but be aware that it may need adjustments based on your specific requirements and the version of Xeon Phi you are using:

1. Prerequisites:

   • Intel Parallel Studio XE: This suite includes compilers, libraries, and tools for high-performance computing. Ensure you have the appropriate version for your Xeon Phi.
   • OpenSSL Source Code: Download the OpenSSL source code from the official website.

2. Install Intel Parallel Studio XE:
   Make sure you have the Intel C++ Compiler and other necessary tools installed.

3. OpenSSL Configuration:

   • Open a command prompt in the OpenSSL source code directory.
   • Set environment variables for the Intel compiler:

     arduinoCopy code
     set CC=icl
     
     set CXX=icl
     
     

   • Configure OpenSSL for compilation:

     cssCopy code
     perl Configure --prefix=<install_path> VC-WIN64A
     
     

   • Run perl Configure list to see the available configurations. Choose the appropriate one for your needs.

4. Modify Makefile:
   Edit the Makefile in the OpenSSL source code directory:

   • Change the value of CC and CXX variables to icl.
   • Set CFLAGS and CXXFLAGS as needed for your Xeon Phi architecture.

5. Compilation:
   Run the following commands:

   Copy code
   nmake -f ms\nt.mak
   
   nmake -f ms\nt.mak install
   
   

6. Test:
   After the compilation is complete, test the OpenSSL library to ensure it works as expected.

Please note that building OpenSSL for Xeon Phi on Windows is not a straightforward task and may require a deep understanding of both OpenSSL and the Intel Parallel Studio toolchain. It's recommended to consult the Intel Xeon Phi documentation, OpenSSL documentation, and Intel Parallel Studio documentation for detailed guidance and potential challenges specific to your setup.

Additionally, consider reaching out to the Intel developer community or relevant forums for assistance, as building software for specialized architectures like Xeon Phi can be complex and may require expert-level knowledge.
