+  DBCSR is a library designed to efficiently perform sparse 
+matrix-matrix multiplication, among other operations. 
+  It is MPI and OpenMP parallel and can exploit Nvidia and AMD GPUs via 
+CUDA and HIP.
+  DBCSR was developed as a part of CP2K, where it provides core 
+functionality for linear scaling electronic structure theory. It is 
+now released as a standalone library for integration in other projects.
+
+This requires a MPI implementation, however the package isn't working
+with mpich. Use openmpi instead.
+
+* HIP and OpenCL still experimental

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
