Bug #1156
mdrun -nt > 1 crashes with old tpr
Description
As reported here http://lists.gromacs.org/pipermail/gmx-users/2013-February/078961.html mdrun 4.6 crashes with more than one thread when run with a particular old tpr file. Initial debugging points to initiation of new data structures that are not present in the old tpr file (line 569 below).
567 block_bc(cr, fep->n_lambda);
568 snew_bc(cr, fep->all_lambda, efptNR);
569 nblock_bc(cr, efptNR, fep->all_lambda);
It runs with one thread.

#1 Updated by David van der Spoel over 7 years ago
- Target version set to 4.6.1
#2 Updated by Peter Kasson over 7 years ago
I have also encountered this problem on multiple TPR files FWIW.
#3 Updated by David van der Spoel over 7 years ago
Additional information: the routine
static void do_expandedvals(t_fileio *fio, t_expanded *expand, t_lambda *fepvals, gmx_bool bRead, int file_version)
is only called for new files (tpx_version > 79) therefore the rest will be initialized with NULL or 0.

Looks like it's probably my fault, then. I'll see what I can come up with to fix.

Posted a fix. I believe this only affects tprs with version < 64.

Is this a duplicate of #1131?

Could you send me the patch? I prefer to use gromacs4.6 because it runs slightly faster than 4.5.
Here is my email address: iwnking@gmail.com
Thanks a lot:)
