parallel processing with MPI

[dkkim]

Hi~
I'm a graduate student in SNU, Korea.

I have researched about soil-structure interaction...
By the way, It takes too much time to analyze it.

so I complied the OpenSees program(ver 1.7.1) to a MPI machine in my univ.

It works in serial processing.
But It does not run in parallel processing.

Do I have to add another source file to use opensees with MPI?
or make a souce file to split the original file?

Would you teach me about that??? ^^;;

Thank you.

you might want to wait until Frank's back at the end of the month.

Try our implementation of PDD available at:
http://sokocalo.engr.ucdavis.edu/~jeremic/PDD/
and see files, and documents in there

in the sequential version make sure you are using a sparse solver if the problem is large.
for our interests you might also try describing your model, e.g. number of elements and nodes, 2 or 3d, material types. if you could also profile the execution of a few steps so that we can see where the time is being spent.

if you need to build the parallel version on an mpich machine you need to change the Makefile.def. have a look at the Makefile.def.UNIX_CLUSTER in the MAKES directory.

Dear all,
I am trying to build the parallel version. Where can I find the libraries listed below? I dont have any of them in the OpenSeesMPI directory.
FE_LIBRARY = $(HOME)/MPIlib/libOpenSees.a
NDARRAY_LIBRARY = $(HOME)/MPIlib/libndarray.a # BJ_UCD jeremic@ucdavis.edu
MATMOD_LIBRARY = $(HOME)/MPIlib/libmatmod.a # BJ_UCD jeremic@ucdavis.edu
BJMISC_LIBRARY = $(HOME)/MPIlib/libBJmisc.a # BJ_UCD jeremic@ucdavis.edu
SUPERLU_LIBRARY = $(HOME)/MPIlib/libSuperLU.a
FEDEAS_LIB = $(HOME)/MPIlib/libFedeas.a

Ok, I have understanded, I have to create the folder and the lib files are made automatically...
Thanks

why i can't obtain the .o files named KinematicHardening.o, TclKinematicHardening.o, and TclNewUniaxialMaterial.o

the compile information like these:
Unknown target KinematicHardening.o, try: make help
Unknown target TclKinematicHardening.o, try: make help

Unknown target TclNewUniaxialMaterial.o, try: make help

when the make procedure in the uniaxial directry.

can you help me, please?
