Nastran SOL700 shared memory parallel 1

[Zeck]

Hello,
I want to use all cores of my CPU during running SOL 700. SMP command doesn't work.
How?
Thanks for help.

You need and advanced License. With a basic license of Nastran you could use only four core with PARALLEL = 4

I ran SOL 700 using CPU with only two cores and dytran-lsdyna.exe used only 50 % of the CPU (I tried commands parallel=2, smp=2 and nproc=2).
There must be some command or something which forces to use all cores but unfortunately I don't know it.
In the picture is shown usage of the CPU during running SOL 700.
Thanks for help.

The following is an extract from the MSC website on how to run sol700 jobs in parallel on windows platform.

**********
Parallel Processing (SMP) MDR3 Sol700 in WIN/XP

1. Install Microsoft Compute Cluster Pack. This can be installed from the Microsoft web site at the URL:

http://www.microsoft.com/downloadS/...09d-9cb3-02312bc23bfd&displaylang=en#filelist

The file name is sdk_x64.msi (for WIN/XP/Vista/Windows7 64-bit OS)

2. Edit the SOL700 execution control card in the input deck as follows:

SOL 700,129 PATH=3 STOP=1

3. Create a file named sol700.pth in the working directory with the following contents:

C:\MSC.Software\MD_Nastran\md2008\dyna\run_dytran
exe=C:\MSC.Software\MD_Nastran\md2008\dyna\dytran-lsdyna
nproc=2
memory=30m
debug=yes

The typical MD Nastran installation directory is used here.

exe=C:\MSC.Software\MD_Nastran\md2008\dyna\dytran-lsdyna (This line is optional if the default installation of dytran-lsdyna executable is used)


nproc=2 is used for two processors

memory=30m is used for 30MB

The memory and debug lines are also optional.

MD Nastran (MDR3) Sol700 parallel can be now run with this set up.
