[gmx-users] Compile Gromacs with OpenCL for MacBook Pro with AMD Radeon Pro 560 GPU

[Michael Williams]

Hi Roland,

Thank you for the reply. The file (nbnxn_ocl_kernel_pruneonly.clh) does exist in that folder, so I’m not sure why it isn’t being located. I’ve downloaded the latest versions of Gromacs, and I will try building them as soon as I can. 

Is there any reason to specify -DGMX_OCL_NB_CLUSTER_SIZE=4 as mentioned in the install manual for Intel GPUs? Based on the output below, Gromacs seems to recognize the AMD GPU, although the laptop does also have an integrated Intel graphics chip. Thanks again,


Mike
