[Help] Radioss with Nvidia CUDA 10

Hello everyone:

Me and my team works with radioss for quite long time, recently we want to start to use GPU accelerated computing to enhance our performance.

I want to ask for some guide about implementing Intel mpi on a single work station with centos which works with Nvidia CUDA.

The workstation uses fully functioning centOS 7.6 latest release, Nvidia CUDA 10 with 410.48 driver

CPU: Intel® Xeon® Platinum 8168 Processor

GPU: NVIDIA Quadro P4000

RAM: 96 Gb DDR4 2666

I already installed Intel MPI 2018.0.128.

I followed the advanced installation guide of Altair Hyperworks 2017.

When I try to use terminal to run a mpi test:

$ [root@localhost ~]# 2017/altair/scripts/radioss -testmpi

The system gives this error:

 

***************************************

[root@localhost ~]# 2017/altair/scripts/radioss -testmpi

ERROR in hwsolver script execution:
 No useful executable found in:
    /root/2017/altair/hwsolvers/common/bin/linux64
***************************************

 

The advanced guide is not very in detail, which gives me a lot of problem to understand.

    Hi shuang_XU

     

    It seems like some executables are missing from your install directory.

    Check whether you have installed the complete package which includes all the executables. Also, confirm the reachability of the executables as mentioned in the image below.

    Hi,

    Unfortunately, GPU calculation is not supported for Radioss explicit.    In older versions of Radioss implicit, the GPU could be used but it is no longer supported.

     

    It is best to use multiple CPU cores to reduce the run time of your simulation.  The Intel MPI is included in Radioss 2017 installation so you should be able to use the

    <install directory>/altair/scripts/radioss -np # input_0000.rad where # is the number of cores you want to use to run your model. 

     

    Thanks,

    Andy
