[gmx-developers] Is there any hip version of gromacs?

[Benson Muite]

Hi Zhang,

This is interesting, though  maintaining a large number of accelerated 
versions may be challenging. OpenCL is more portable than HIP, Vulkan 
looks like a possible well supported accelerator API. Is your code 
openly available?
