Dear Li Qiang,

it seems another guy get the same error(cannot pass gmxtest with
rb1/acetonitrilRF) as me. and it sounds like the compatible problem
between GROMACS 3.3.2 and and UBUNTU 7.10. Both are rather new.

Herein I just suggest and hope others may help to install 3.3.2 on new
ubuntu 7.10 to confirm the problem.


I have just installed 3.3.2 on my (64-bit) Ubuntu 7.10 machine (dual-core Athlon64 4000+, 2GB RAM) and run the serial tests. All the single and double precision tests passed with and without assembly loop optimizations so I guess it's not simply Ubuntu 7.10 that is to blame (unless what you are seeing is a 32-bit distribution-specific problem?).
Quite likely a 32-bit specific problem.

Could anyone install dmalloc and configure gromacs to build with dmalloc and run the test with the new mdrun?

I did mine and found that it was due to one line in mshift.c "srenew(g->edge[0],n); "

mdrun output:
realloc for g->edge[0] (24 bytes, file mshift.c, line 251, g->edge[0]=0x0x 1)


So is this in the rb1 test? I compiled the code with dmalloc on my Mac and it passed all tests (except dec+water due to very small energy differences).

Regards,
Yang Ye


Cheers,

Bruce
