The ABINIT Users Mailing List ( CLOSED )

[prendergast2@llnl.gov]

Hi Nichols,

I ran into this problem before. If you look for my name in the Mailing List 
archives you should find a posting on this.

Basically, compilers don't like it if you put an exit statement in the middle 
of a loop that is expected to be parallelized using OPENMP, since if one 
processor exits the loop, the others won't know and the processes will no 
longer be synchronized for communication at the end of the loop.

I had to edit all the files with OMP directives that contained exit 
statements. This involved some 'grep'ing for OMP and exit. After that the 
program managed to compile. 

*However*, I could never get abinip (compiled with OMP on an Intel 
architecture) to run without a segmentation fault anyway. I think this is a 
more fundamental problem either with the code or the compiler. I've only ever 
managed to compile abinip with OMP directives on a DEC/Alpha, where it works 
very well.

Please let me know if you get the code to compile and run on your Intel 
architecture. And how efficient this is.

Good luck,

David.

Hi,

I'm trying to compile ABINIT 4.2.4 for use with OPENMP on Intel Cluster.
I am using version 8.0 of the Intel Fortran Compiler. Has anyone run
into this error?
