     The only workaround is to not use inter-node GPU-aware MPI.
 
-    For users of CP2K encountering this issue, one can disable the use of COSMA, which uses GPU-aware MPI, by placing the following in the `&GLOBAL`` section of your input file: 
-    ```bash
-    &FM
-    TYPE_OF_MATRIX_MULTIPLICATION SCALAPACK
-    &END FM
