Error using more than 1 processor

macarojaime · Post by **macarojaime** » Mon Oct 13, 2008 4:32 pm

Hello,

I have installed and configured all the files so I can make use of OpenSeesSP. I followed very carefully all the steps in doing this.

Whenever I try to run (for instance):

mpiexec -np 2 OpenSeesSP.exe C:\model.tcl

I get the following error text:

Slave Process Running 1

FEM_ObjectBrokerAllClasses::getNewElement - - no Element type exists for class tag 7003
FEM_ObjectBrokerAllClasses::getNewElement - - no Element type exists for class tag 7003
FEM_ObjectBrokerAllClasses::getNewElement - - no Element type exists for class tag 7003
FEM_ObjectBrokerAllClasses::getNewElement - - no Element type exists for class tag 7003
FEM_ObjectBrokerAllClasses::getNewElement - - no Element type exists for class tag 7003

Now, when I change the np to 1 (instead of 2), the interpreter works perfectly, giving me the same results as if I were using single computing, and taking the same time to process my model.

My system is Windows Vista, and I am working in a laptop computer with AMD Turion X2 processor. I am assuming I have 2 CPUs (duo-processor). Am I wrong?

Thank you.

To be more precise, my processor is an AMD Turion™ 64 X2 Dual-Core.

the element you are using could not send/recvSelf .. i have updated the element .. can you send me the materials you are using so i can ensure they have the needed routines before i post a new .exe

I appreciate it Frank. Does it mean I have to download a newer version of the binary and try it again?

I am using nDMaterial NewTemplate3Dep (from UCDavis). Please let me know if I should change something.

Thank you.

what options are you using to build the template material with.

Frank, I did download the binary again and tried to run my model, obtaining the following NEW error log in the DOS shell:

i have not updated the working element yet .. it looks like i have to add some code to the NewTemplate as well .. just want to get the options you pass into the material so i get them all.

can you send me the file .. i don't have any example to test and your variables are not defined fmckenna AT berkeley DOT edu

Frank,

I am running into some inconsistencies in the results (stress calculations) after trying modelling a looser soil layer on top of a denser one. I believe there might be a bug in the code. I am still running with 1 processor, eventhough the commands are setup for parallel computing. This was working fine for a uniform soil mass but not anymore for non-uniform soils. I will try to solve this by contacting the author and then I'll get back to you.

Thanks for your time.

Maria

Hi Frank,

I'm going to email you the file of the script I'm using right now.

I am using Brick20N_u_p_U elements and nDMaterial NewTemplate3Dep material model.

This is the error message I recently got:

WARNING MumpsParallelSolver::solve(void)- Error -10 returned in substitution dmumps()

WARNING KrylovNewton::solveCurrentStep() -the LinearSysOfEqn failed in solve()
ERROR 1 during ass_niv1 140 223

WARNING MumpsParallelSolver::solve(void)- Error -8 returned in substitution dmumps()

WARNING KrylovNewton::solveCurrentStep() -the LinearSysOfEqn failed in solve()
ERROR 1 during ass_niv1 140 223

The 3rd and 4th warnings are repeated over and over again.

I will appreciate you helping me with this one.

Thanks,

Maria

I changed the system from Mumps to UmfPack, thinking that my initial problem was the parallel interpreter, so I ran it in the sequential OpenSees.exe.

I got similar error messages with the sequential interpreter as well, so now I believe my problem is in the actual solving of each element. By the way, I am only applying a gravity force by means of BrickW element load.

Before, I was using 8-node elements without this type of problem in the solution. These error messages appeared since I tried to implement 20-node elements.

These are the error messages running in the sequential interpreter:

UMD2FA: matrix is singular. Only 908 pivots found.

WARNING UmfpackGenLinSolver::solve(void)- 4 returned in factorization UMD2FA()

WARNING KrylovNewton::solveCurrentStep() -the LinearSysOfEqn failed in solve()

Please help.

I am trying to run OpenseesSP on my intel laptop which am sure has more than 1 processor, it seems to run when I use mpiexec -np 2 Opensees.exe ex1.tcl but it will not run when I use mpiexec -np 2 Opensees.exe ex1.tcl

The OpenSees Community

Sequential does not work either
