Hello,

I compiled charm++ with support for fast message-logging protocol:

./build charm++ net-linux-x86_64 mlogft


And then I tried to execute the example 'jacobi3d' located in:

net-linux-x86_64-mlogft/tests/charm++/jacobi3d/

using the following line:

./charmrun ++p 16 ++nodelist /root/nodelist ./jacobi3d 512 512 256 64 64 64

arg_read_pes 16 arg_requested_pes 16
Charmrun> started all node programs in 6.788 seconds.

The application hangs when performing the first checkpoint.
I dont have any problem when I used 'syncft'
I have this problem with version 6.6.0 of charm and with the current version from the git repository.

Any ideas about what I'm doing wrong? Should I add more options when compiling?

Thank you
