Subject: [ALPS-users] MPI problem
Hello,
I met the problem on my CENTOS 7 installed on station with 24 threads. After:

~/opt/bin/cmake  -D Boost_ROOT_DIR:PATH=~/alps-2.2.b4-src-with-boost/boost/ -D MPI_C_LIBRARIES=/usr/lib64/openmpi/libmpi.so -D MPI_C_INCLUDE_PATH=/usr/lib64/openmpi/include/ -D MPI_CXX_INCLUDE_PATH=/usr/lib64/openmpi/include -D LPSolve_LIBRARY=/usr/lib64/liblpsolve55.so -D LPSolve_INCLUDE_DIR=/usr/include/lpsolve/ -D HDF5_LIBRARIES=~/opt/lib/libhdf5.so -D HDF5_INCLUDE_DIR=~/opt/include/ -D SZIP_LIBRARIES=/usr/lib64/lib/libsz.so -D SZIP_INCLUDE_DIRS=/usr/lib64/include/  ~/alps-2.2.b4-src-with-boost/alps/

I receive:

in ccmake I see MPI ON.  make and make tests (all passed) go smoothly. In tutorial runs I see however mess with MPI=24 while everything goes OK with MPI=1. 
Is something wrong in my HDF5? 

In docker hub I found dolfim/alps but could not run probably because of some path problems. Anyone did it successfully?
Regards

Subject: Re: [ALPS-users] MPI problem
The configuration seems fine and the hdf5 message are not related to the MPI execution.

Can you clarify a bit what you mean by “see a mess”? How do you run the mpi application?

​When I run ​e.g. tutorial7a.py :
..........................
#pyalps.runApplication('spinmc',input_file,Tmin=5)
# use the following instead if you have MPI
pyalps.runApplication('spinmc',input_file,Tmin=5,MPI=24)

pyalps.evaluateSpinMC(pyalps.getResultFiles(prefix='parm7a'))
.................................
result is different when MPI=1, 2, 8, 12, 24.
I figured out that some temperatures are missed in result file. For temperatures well done all tasks have: ...out.run1 while the missed have more (run1, run2 and so on ). Finally while magnetization is collected from all temperatures, susceptibility and specific heat and Binder cumulants only from those which have only run1. Only MPI=1 gives full result.
BTW it seems that for linear chain problem does not exist (Ising, Heisenberg, spinmc, loop).
