Hellow..

I compiled the OS ver 1.7.5 with Mumps solver.

So, I tested it with a parallel example tcl script (ex4.tcl) like below..

# ---------------------------------------------------------------

set pid [getPID]

set np [getNP]

if {$np != 2} {

puts "ONLY WORKS FOR 2 PROCESSORS"

exit

}

model BasicBuilder -ndm 2 -ndf 2

uniaxialMaterial Elastic 1 3000

if {$pid == 0} {

node 1 0.0 0.0

node 4 72.0 96.0

fix 1 1 1

element truss 1 1 4 10.0 1

pattern Plain 1 "Linear" {

load 4 100 -50

}

} else {

node 2 144.0 0.0

node 3 168.0 0.0

node 4 72.0 96.0

fix 2 1 1

fix 3 1 1

element truss 2 2 4 5.0 1

element truss 3 3 4 5.0 1

}

# ------------------------------

# Create the recorders

# ------------------------------

recorder Node -file node4.out.$pid -time -node 4 -dof 1 2 disp

# ------------------------------

# Start of analysis generation

# ------------------------------

# Create the system of equation, a SPD using a band storage scheme

system Mumps

numberer ParallelPlain

constraints Plain

integrator LoadControl 0.1

test NormDispIncr 1.0e-12 3

algorithm Newton

analysis Static

analyze 10

print node 4

# ---------------------------------------------------------------

but there are some errors..

1.

the analysis was done at ONLY PID 1, not at PID 0.

so, ONE recorder(node4.out.1) file was created.

but, the result are zero.

and the Processor 0 goes on, does not stop.

so, I changed the Mumps solver to ParallelProfileSPD.

It created two result files(node4.out.0, node4.out.1) and reasonable values..

I think that it's Mumps problem.

What should I do to fix it?

2.

This is just a question about message.

what does this line mean?

Vector::Vector(int) - size 0 specified <= 0

3.

When I tested my large model, the mumps solver created many lines like below..

Vector::(loc) - loc 3554 outside range [0, 329

Vector::(loc) - loc 3555 outside range [0, 329

Vector::(loc) - loc 3556 outside range [0, 329

.... many lines.....

[3] MPI Abort by user Aborting program !

[3] Aborting program!

what is the problem...?

What I'd like to do is a large scale soil-structure interaction analysis

With UCSD nonlinear soil material , a parallel machine and Mumps solver.

Would you advise me about these things...?
