I am trying to implement GPU computing in the Acoustic analysis.
I have seen some examples in the manual below (chap:9)
but I am unable to understand the exact procedure.
They say keyword gpugp='value' is used but where in the GUI it needs to defines?
Please guide me if you know about this feature.
In general, command line control is done on the Solver Parameters dialog (RMB on the active solution and pick 'Edit Solver Parameters')
Inputs for several command keywords have an explicit setting in the dialog. For example, keyin a value into the memory input on the dialog results in 'mem=value' being written to the command line.
There is an 'Additional Keywords' entry that can be used for specifying any additional command line options. The string that you type into this box will be directly appended to the command line used to launch the solver process.
Per Chapter 9 in the NX Nastran Parallel Processing Guide, "Value" is one of the following:
So, the simplest form to enable the GPU is to specify gpgpu=any in the additional keywords section of the Solver Parameters dialog
Thanks for the reply.
I have used value 'any' and it is compiling now without any error but no change in computation time.
I want to reduce the computation time of the simulation.
GPU Computing benefits are more than marginal with NX Nastran... What type of solution and model size? And equally importantly, what kind of GPU are you trying to use?
In my opinion, a faster scratch file, more mem assign to the solve and/or a larger buffsize would probably more effective...
