fatal internal in brackting...

#1 Post by Danny » Mon Oct 22, 2007 4:16 pm

I'm running some tests to time my vasp executables(different ways of compiling version 4.6.31) and see how they respond to different combinations of processors and threads.
All goes well for all combinations I try except 1 cpu 4threads and 1 cpu 8threads(1 cpu 2 threads, works nicely and N cpu 4&8 threads, N>1 also does alright) in this case the job crashes with the error:

Code: Select all

ZBRENT: fatal internal in brackting
             system-shutdown; contact gK immediatly
With all the versions I tried already only for the combinations stated above the job goes bad.
(all vasp parameters are exactly the same)

Are there any suggestions I could implement in my compilation to solve this problem or are they not related to the vasp compilation completely?

thx
Danny

the error messsage says that the geometry optimization cannot find a reasonable next geometry by BRENT's algorithm (root bisectioning). This has nothing to do with the hardware or the code itself, but is due to the ionic optimization "history" of your system.
please check
1)( best to do in XDATCAR ): did the system converge into an unreasonable geometry? if yes: set POTIM to a smaller value (default=0.5) and/or change the optimization algorithm (IBRION)
2) check EDIFFG: a calculation can be regarded as converged if the maximum remaining forces are not larger that 0.01eV/Ã…. (EDIFFG = -0.01). if a much higher precision is afforded, you may have to set IBRION=1; ADDGRID=.True.
3) please in any case also check if each ionic step is converged electronically (ie the forces are calculated after the EDIFF-criterium is matched, not because the electronic convergence is not reached after 60 el. steps and vasp therefore breaks the electronic scf iterations for this geometry. If the latter is the case, the calculated forces (and therefore the next ionic configuration) are unreasonable.

if this has nothing to do with the hardware nor the code then doing exactly the same calculation(i.e. same input files) should give the same error? Am I correct?
If so, then why does the same calculation run on 16 CPU's run perfectly, and when I run it on 16CPU's each running 4 threads or 8CPU's running 2 threads each, the calculations gives the above error?
All of them should fail if it were only a geometry problem.

(same goes for more than 4 threads...but when I run the job on say 4 cpu's, 4 threads or 8 threads /cpu it works perfectly again.)

As can be seen from the last posts, geometry can't really be the cause, because then the job should crash in all cases given here.

any thoughts what could be the cause and how it could be resolved?

thx

Hi,

I'm still interested in what might be causing this problem with VASP.

thanx

Hi,

I'm still interested in what could cause this problem, since it is clear from the above examples that it has no connection to the actual geometry of the system.

Or should I direct my question elsewhere?
I really want to understand the cause of this problem.

thanx
Danny

maybe the reason is the following: some compilers automatically support OPEN_MP if several processes are running. This should NOT be done, because all parallelization is done explicitely in the vasp code itself. (the errors at the first mixing step after the pre-conditioning electronic steps may be due to some parallelization-related problem)

Therefore please add a line
export OMP_NUM_THREADS=1
in your .bashrc file to suppress any additional parallelization which is not encoded in vasp itself.

Thank you for the confirmation. I already suspected something like this, but I was told MPI and the Open_MP(done by the compiler) would not clash ...it seems they do, and thus it is a code-related problem.

well, in VASP all reasonable parallelization is hard-coded, all that has to be done is to tell the compiler to do no additional Open-MPI parallelization (this behaviour is compiler-dependent), or to set the environment-variables such that any additional parallelization is suppressed.

Does the default MKL_DYNAMIC in MKL 10.1 detect the optimal threading and solve the parallelization inefficiency for VASP?
http://software.intel.com/en-us/article ... threading/

I have Intel E5410 8 cores per node (2 quads). When it's using 4 cores on the node, VASP will be threaded to 120-150% CPU for all 4 VASP processes. And with 8 processes, it comes back to 100% CPU per process.

I optimize a H2 molecule for VASP benchmarking. Within the same node, ppn=1 as 100% walltime:
ppn=2: 0.70
ppn=3: 0.54
ppn=4: 0.52
ppn=5: 0.45
ppn=6: 0.62
ppn=7: 0.81
ppn=8: 0.60

Is this normal for an 8-core node?
Should I use a bigger system as benchmark?
Or use OMP_NUM_THREADS = 1?

Thanks in advance for your help.

Here is a ppt presentation by Intel:
MKL PPT

On page 11 they state that if the thread count is larger than physical core count, it will be automatically reduced to the latter.

Thoughts ?!
