Compiling the kernel for a specific GPU
- Windows 7 or up
- Catalyst 14.6, 14.7, 14.9, 14.12 (those are confirmed to work)
- AMD Radeon gfx with GCN chip (HD7xxx and up)
- sgminer 5.1
Step 1: Download HetPas??????_Groestl.zip! The latest version can be found in the [Download Area] on the MenuHeader of this blog.
Step 2: Unpack it to a folder that has write access (UAC let it to write there).
Step 3: Turn off DEP for HetPas.exe. (If you don’t know what is this and HetPas.exe wont start -> google “Turn off DEP”)
Step 4: Open HetPas.exe and load [F3] the “groestl/groestl_isa.hpas” program.
Step 6: Run “sgminer.exe -k groestlcoin (…your usual command-line comes here)” and then stop it in order to precompile the original groestlcoin.cl opencl kernel.
Step 7: Look for the precompiled binary file that just have been created in the same path as sgminer.exe. The name of the file is something like this: “groestlcoinXXXXgw256l4.bin“. To the place of XXXX your graphics chip’s name will go. In my case it is “groestlcoinCapeverdegw256l4.bin”.
Step 9: Run sgminer.exe but now with the new binary!
