Thanks Constantinos.

I have gone through the site you sent to me, however whenever I want to enable FT, it will not be enabled.

this is what I got.
/openmpi-1.6# ./configure --enable-ft-thread --with-ft=cr --with-blcr=/usr/src/blcr-0.8.2
#FT Checkpoint support: no (checkpoint thread: no)
"FT Checkpoint support: no (checkpoint thread: no)"

Please is there a special way to enable the FT?

I also want test with real application that runs for about 30 mins but I cannot easily lay my hands on any.

Please help.

Thanks in advance.

Regards,
Ifeanyi

Hi,

you may start by looking at http://www.open-mpi.org/faq/?category=ft
which leads you to
https://svn.open-mpi.org/trac/ompi/wiki/ProcessFT_CR
and
http://osl.iu.edu/research/ft/ompi-cr/

The latter is the most up-to-date link and probably what you are looking for.


HTH,

Dear,

I am a new user of open mpi. I have already installed openmpi and build hpl. I want to checkpoint/restart hpl and compare its performance

Please can you point me to a useful link that will guide me through this checkpointing of hpl.

thanks in advance.
