Subject: FullMPI for 1.7.7
john-1.7.7-jumbo-1-fullmpi-9.diff.gz is now uploaded to the wiki. It has
a couple of improvements compared to 1.7.6-fullmpi8.
* -DHAVE_MPI, passing "the sha1sum test" when disabled.
* Do not show any ETA until progress is above 0.00%. NOTE that this
should really be in non-MPI too but it's currently ifdef'ed.
* Incremental mode now has progress status and ETA (note the previous
point about muting though), but not after resuming a job. It's useful
for --inc=alnum or smaller keyspaces and/or very fast formats.
* Incremental mode: the empty string candidate is now only tested on one
node.
* If one node runs out of hashes, it sends an abort to the other nodes
(they would otherwise keep attacking already cracked hashes).
* If a node stops with error (eg. file locking problems because of
flakey NFS) it will send an abort to all other nodes.
* Jobs could not be resumed if some nodes had finished. Now the .rec
file does not get deleted until all nodes are done.
* Mitigated the interleaving of output lines when showing status for a
running job (it doesn't happen if you print everything in one call).
* Higher preference of distributing rules instead of words.
* --mem=0 will force loading of wordfile to memory, regardless of size.
This too could be in non-MPI as well IMO.
* Added some compilation hints to README.mpi.
I also did some tweaking so it applies together with the utf8 patch
without rejecting.
The code has been stable for a long time now. If you get problems, they
are most likely due to NFS problems (for multi-host setup) or using a
buggy MPI version. I recommend using latest stable OpenMPI but mpich2
and even mpich1 is supported.
enjoy!
