[gmx-users] Error: not enough memory

[Sun Iba]

Dear Gromacs users

I am doing an mm_pbsa analysis of my protein-ligand complex. I installed
and it was nicely running on my workstation Z820. However, on a similar
system, i installed using same steps but it is giving following error:


*Not enough memory. Failed to calloc -1082130432 elements of size 4 for
grps[j].nm_ind(called from file
/home/rajendra/software/gromacs_source/gromacs-5.0.5/src/gromacs/fileio/tpxio.c,
line 2510)*

When i checked the memory of system it is enough i believe:




*sggswu at sggswu:~/Documents/suniba2$ free -m              total
used        free       shared   buffers     cachedMem:         15971
6594       9377         14         66       5401-/+ buffers/cache:
1125      14845Swap:        16306          0         16306*

Please help me with error. Is this some gromacs error or shall i post this
problem in mmpbsa mailing forum?

WIth Regards
