Hi All,

I have been evaluating which ARMCI_NTEWORK most suitable for a socket-based KNL Cluster; the processor type is KNL 7210 @ 1.30GHz, and each node has 192GB memory, OS is RedHat 7.3.

ARMCI_NETWORK=MPI-PR, OpenIB and ARMCI-MPI+CASPER have been evaluated. All 3 copies of NWChem were compiled using the same set of environmental variable, the script is given the the bottom part of this thread. Intel Compiler v17.0.1 and Intel MPI Version 2017 Update 1 Build 20161016 were used for the compilation.

Initially I would like to evaluate the performance for a TCE:CCSD(T) calculation of a pentacene molecule taken which have been used for NWChem the benchmark (http://www.nwchem-sw.org/images/Pentacene_ccsdt.nw), however the SCF timing result for the ARMCI-MPI+Casper is too slow compared with other ARMCI network, so I would like to check if any part of my compilation or runtime variable are not correct before going further to CCSD level:


For MPI-PR
            iter       energy          gnorm     gmax       time
----- ------------------- --------- --------- --------
1 -841.3354871523 2.54D-03 3.19D-04 49.8
2 -841.3354832032 1.14D-03 1.43D-04 89.9
3 -841.3354832406 1.57D-06 2.64D-07 113.7
Time for solution = 111.5s

For OpenIB
           iter       energy          gnorm     gmax       time
----- ------------------- --------- --------- --------
1 -841.3354871523 2.54D-03 3.19D-04 53.4
2 -841.3354832032 1.14D-03 1.43D-04 95.9
3 -841.3354832406 1.57D-06 2.64D-07 121.1
Time for solution = 116.4s

For ARMCI-MPI
           iter       energy          gnorm     gmax       time
----- ------------------- --------- --------- --------
1 -841.3354871523 2.54D-03 3.19D-04 236.9
2 -841.3354832032 1.14D-03 1.43D-04 923.4
3 -841.3354832406 1.58D-06 2.64D-07 1211.7
Time for solution = 1263.4s


Thanks!

Thanks a lot for your feedback
You might want to try the following variables for MPI-PR, since moving as much MPI communication as possible to the eager protocol should decrease latency.

setenv I_MPI_EAGER_THRESHOLD 32768
setenv I_MPI_DAPL_DIRECT_COPY_THRESHOLD 32768

Thank you Edo,

(1) What is the suitable combinations of OMP_NUM_THREADS and MKL_NUM_THREADS on a 64 cores KML systems? I believe thread based parallelization is used by SCF through MKL, and based on my observation, if I assign 1 MPI rank (for OpenIB), or 2 MPI ranks (for MPI-PR), on each node, it will not be used for more than 20 cores regardless the setting of MKL_NUM_THREADS (I set it 60). In other words, I have to assign more MPI rank on each MKLnode to fully utilize all 64 cores...

Update: I assign 5+1 MPI ranks on each node, and it roughly speeds up by 5 times in SCF. Am I suppose to run 60 MPI ranks on each node?

(2) For ARMCI-MPI+CASPER, I observed that SCF (and subsequent integral transformation for CCSD calculation) was run only 1 thread on each node, that's the reason why it is 4 times slower than OpenIB and MPI-PR. how do I enable the multi threads parallelization for AMRCI-MPI+Casper?


(3) For OpenIB and MPI-PR, the SCF and CCSD calculations are finished in half an hours on 20 KNL nodes, but it was stuck in the (T) calculation, it could not finish in 20 hours.


 Iterations converged
CCSD correlation energy / hartree = -2.916922299620284
CCSD total energy / hartree = -844.252405540227414

Using sliced CCSD(T) code

If I disable the sliced (T) algorithm, there will be a "ccsd_t: MA error sgl 17596287801", I believe it is due to insufficient of local memory.

3 weeks ago, Thomas Dunning has presented the NWChemEX project at a Singapore conference, and he mentioned that they have achieved 1 PF/s on 20K nodes in Blue Water with a more efficient (T) algorithm, has this been implemented to the current version of NWChem?

Thanks!

CCSD can be calculated fairly efficiently on KNL, but there is no way to get the (T) calculation complete, does anyone has the same problem?

The CCSD(T) results that Dunning presented likely correspond to http://pubs.acs.org/doi/abs/10.1021/ct500404c and I think they used the semidirect module rather than TCE.

I don't know what the issue with ARMCI-MPI+Casper is, but you should just use whatever works best. ARMCI-MPI exists as an alternative for cases where ARMCI isn't working well. If ARMCI works well, there is no reason not to use it. My guess is there is something wrong in the usage/configuration of ARMCI-MPI, Casper, or MPI, but I don't have time to debug it right now.

"mpirun -perhost 1 -genv CSP_NG 1" runs one MPI rank per node, does it not? I don't know how Casper even functions in that case. You need to launch N+G processes per node, where N is the number of application processes per node, and CSP_NG=G.

Thanks Jeff!
However, I believe the main reason why my copy of ARMCI-MPi+CASPER is much slower because it is only running in single thread while other copies using at least 3 - 4 threads on each MPI rank; I don't know why OpenMP and MKL thread is not running in this case.

Thanks for Edo's help, I managed to get the (T) calculation completed using the source code downloaded from the developer trunk (in which setting USE_F90_ALLOCATABLE=T and USE_KNL=y, which defines DINTEL_64ALIGN in the compilation)
