I installed sage 7.1 from source codes, and now it works perfectly.
Thanks very much!

well, you might try Sage 7.1 binary, perhaps it would work better...

I think I downloaded the binaries. Thanks for your suggestions. I will try
it.

Have you built Sage from source? If not, it could happen, in principle,
that lapack/atlas/blas shipped
do not quite work on your system...
If you built it from source, did you do anything special to build Atlas in
particular?
You can also try building csdp completely separately from Sage, usin
Yes, it still works on many other graphs.

It does work on some graphs, still, right?
It's a high-end relatively new CPU, perhaps Atlas and/or gcc has a problem
with it?
Can you post the output of 'ldd theta', i.e.

I just did what you suggested, and it didn't work. I got those messages:
(sage-sh) shhu@shhu-ee-tau:~$ theta 2k2

save it to a file named, say, 2k2, fire up "sage -sh"
and run
theta 2k2
I get

all this works for me just fine:

Can you try the following:

What is your L[68] ?
This is probably something like a graph without edges...

Thanks for the comments.
I have installed package 'csdp' before. I got this error after I installed
it.

The error you get is quite strange. On my computer with sage-7.1 I got
sage: graphs.CycleGraph(7).lovasz_theta()

Hi guys,
When I try to compute the lovasz theta number of some graph, it says that

for s in V.subsets():
