Thank you for your reply. I'm using a cluster. In that I've to submit the job in queue. I think PBS is there. below is the output which I got when I submitted a job to the cluster

........................../Abhi/............ 82 > acuSub -pb AB35_2 -np 60 -ppn 12 -q acusim -time 4320

So, which command should I use to submit the job ?

the path posted above at 12:08 (today) seems to be correct.

xvfb needs to be installed on the cluster, since the VWT automation calls AcuConslole in the background to setup the case.

Thank you for your reply.

path_to_acuVwt/ ??acuVwt /acuVwt.sh ?? path_to_working_directory parfile_prefix sub num_processors(np) num_processors_per_node(ppn) -q ??acusim?? -time 4320

I've to use acuVwt (or) acuVwt.sh & at the end -q acusim -time xxxx is needed or not ?

I'm getting error If i execute the following commands :

/soft/usr/acusim/HyperWorks/V12.0.310/altair/acusolve/linux64/plugins/bin/acuVwt.sh /soft/scratch/Abhi/BusM1-1/ Bus-M-1 sub -np 48 -ppn 12

/soft/usr/acusim/HyperWorks/V12.0.310/altair/acusolve/linux64/plugins/bin/acuVwt.sh: Command not found.

Also getting error if i try with AcuVwt command instead of AcuVwt.sh

/soft/usr/.../V12.0.310/altair/.../bin/acuVwt /soft/scratch/Abhi/BusM1-1/ Bus-M-1 sub -np 48 -ppn 12

Error 1 Executing: '/soft/.../acusolve/linux64/plugins/bin/acuVwtScript' '/soft/scratch/Abhi/BusM1-1/' Bus-M-1 sub -np 48

What to do ?

instead of '-np 48 -ppn 12' just use '48 12'.

I am getting the same error

I am unable to find the acuVwt.sh

The shell we are using is : /usr/bin/csh

Could anyone help ?

Also, request the URL to a manual where i can find the commands and their arguments ( there is no help given upon using --help or -help after the scripts or the commands )

AcuSolve commands have a help, that can be called by using '-h' option.

Eg. acuVwt -h

Usage: /soft/usr/hw12.0.1/altair/acusolve/linux64/plugins/bin/acuVwt working_directory par_file_prefix

I am bit skeptical about number_of_proc=10 and proc_per_node=10 in the arguments you are using.

Are you using a cluster with job scheduler like PBS or is it a standalone Linux workstation?

What version of AcuSolve and VWT are you using? Is it AcuSolve 12.0 or 12.0.311? You could check using 'acuRun -h'

AcuSolve commands and their arguments are listed in AcuSolve-Programs-Reference-Manual.pdf

Check for a path similiar to this in your installation. It would PDF documents for help.

C:\HW12\acusolve\win64\doc

Alternatively, these manuals are available via Resource Library:

Each node has 20 CPU cores (2 sockets per node, each socket CPU has 10 CPU cores) and there are 8 nodes.

My question is :

number_of_proc refers to CPU sockets or number of processor cores

proc_per_node : refers to CPU sockets or number or processor cores

Request to construct a command requesting 4 nodes (totaling 80 cores)

Thank you

np & ppn were misisng from the first command.

Try starting with following. That would be the easiest way to get started and reduce number of error source.s

/altair/hw/12.0/altair/acusolve/linux64/plugins/bin/acuVwtScript /stage/adarshp/vwtest vwtAnalysis 4 4

It seems Xvfb might not be installed or running.

To see if Xvfb is running: ps -ef | grep -i xvfb

To check if Xvfb is installed: rpm -qa | grep -i xvfb (this is for a RHEL based Linux)
