    9898**Attention:** As of 16.10.2019, there is no support for GPUDirect over EXTOLL. As a temporary workaround, this version of ParaStationMPI automatically performs device-to-host, host-to-host and host-to-device copies transparently to the user, so it can be used to run applications requiring a CUDA-aware MPI implementation (with limited data transfer performance). Support for GPUDirect will be provided by EXTOLL in the near future.

     100**Extoll:** As of 12.12.2019, the first half of the DAM node has Ethernet network (partition=dp-dam,nodeslist=dp-dam[01-16]), the second half has Extoll interconnect (partition=dp-dam-ext,nodeslist=dp-dam[09-16]).
