    8787A release-candidate version of ParaStationMPI with CUDA awareness is also available on the system. It is installed under the GCC stack (run `ml spider ParaStationMPI` to find the relevant installation for CUDA). This version also automatically loads a CUDA-aware installation of `pscom`.

    89 **Attention:** As of 16.10.2019, there is no support for GPUDirect over EXTOLL. As a temporary workaround, this version of ParaStationMPI automatically handles the device-to-host, host-to-host and host-to-device copies transparently to the user and can be used to test the functionality of applications requiring a CUDA-aware MPI implementation. Support for GPUDirect will be provided by EXTOLL in the near future.

    91 **Attention:** As of 16.10.2019, a minor bug in the `pscom/.5.4.0-1-CUDA` module requires the user to explicitly export `PSP_CUDA=1` in order to use the CUDA-aware ParaStationMPI. This bug will be fixed in the next days.
     89**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.
