[petsc-dev] boomerAmg scalability

[Ravi Kannan]

Hi Mark,

 

I downloaded the dev version again. This time, the program crashes even
earlier. Attached is the serial and parallel info outputs.

 

Could you kindly take a look.

 

Thanks,

Ravi.

Hi Mark,

 

Thanks for your efforts.

 

Do I need to do the install from scratch once again? Or some particular
files (check out gamg.c for instance)?

 

Thanks,

Ravi.

I think I found the problem.  You will need to use petsc-dev to get the fix.

Ravi, I forgot but you can just use -ksp_view_binary to output the matrix
data (two files).  You could run it with two procs and a Jacobi solver to
get it past the solve, where it writes the matrix (I believe).

I have attached the verbose+info outputs for both the serial and the
parallel (2 partitions). NOTE: the serial output at some location says
PC=Jacobi! Is it implicitly converting the PC to a Jacobi?

 

Looks like you forgot the attachment.
