[gmx-developers] gmx 3.3_rc1 - block_tx.c error

[David Bostick]

Hi Erik,

I checked out the current CVS version and tested again.  This time, I 
tested a parallel run on 2 processors, which finished successfully.  
However, when I tried on 4 processors, I get the same block_tx.c error as 
before, except that now the version cited for mdrun is 3.2.9_beta.:

Reading file test.tpr, VERSION 3.3_rc1 (single precision)
-------------------------------------------------------
Program mdrun_mpi, VERSION 3.2.90_beta_20040828
Source code file: block_tx.c, line: 74

Fatal error:
0: size=816, len=840, rx_count=0

-------------------------------------------------------

The tpr file is from a version 3.3 grompp. Is it posssible 
that something in the top branch CVS version is wrong?  Previously, the 
mdrun version cited in the error was 3.3_rc1 as follows:

Reading file test.tpr, VERSION 3.3_rc1 (single precision)
-------------------------------------------------------
Program mdrun_mpi, VERSION 3.3_rc1
Source code file: block_tx.c, line: 74

Fatal error:
0: size=0, len=4, rx_count=0

-------------------------------------------------------
