Estimating computing resources for the simulation
by Volodymyr Derzhko 13 Dec '11

Dear Mr. Troyer, I want to estimate how much memory and CPU time the program need to run fulldiag and sparcediag. 1) As I understood, in fulldiag, the main limitation is memory, which have to store the matrix, which is diagonalized. Am I right? 2) What about sparcediag? Does the program also store the matrix, or just generate its elements? Do you think it is possible to find few lowest eigenvalues for the Hubbard model on the 18 sites, with 9 particles (say 4 spins up and 5 down)? 3) Is it possible to have a degeneracy of eigenvalue in sparcediag? 4) How to extract column of eigenvalues from h5-file after running fulldiag? Thank you in advance, Volodymyr Derzhko

Compilation error related to boost_mpi

Hi! I would like to build ALPS 2.0.2 on my Debian Linux system which has Boost++ 1.46 libraries installed. However, I get the build error shown below. I have attached CMakeCache.txt. The cmake command was generated by the Debian build system applied to the old alps_2.0.0~rc4 Debian package (but with the updated 2.0.2 source of course) available at: http://alps.comp-phys.org/static/software/debian/sid/ The cmake command was: cmake /home/tmac/src/alps/alps-2.0.2-r5790-src/alps/. -DCMAKE_INSTALL_PREFIX="/usr" -DCMAKE_C_COMPILER:FILEPATH="cc" -DCMAKE_CXX_COMPILER:FILEPATH="g++" -DCMAKE_C_FLAGS="-g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security -Werror=format-security -Wall" -DCMAKE_CXX_FLAGS="-g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security -Werror=format-security -Wall" -DCMAKE_SKIP_RPATH=ON -DCMAKE_VERBOSE_MAKEFILE=ON -DALPS_BUILD_APPLICATIONS:BOOL=ON -DALPS_ENABLE_OPENMP:BOOL=ON -DALPS_BUILD_FORTRAN:BOOL=ON -DCMAKE_Fortran_FLAGS:STRING=-fopenmp -DCMAKE_SHARED_LINKER_FLAGS="-Wl,--as-needed" -DCMAKE_MODULE_LINKER_FLAGS="-Wl,--as-needed" -DCMAKE_EXE_LINKER_FLAGS="-Wl,--as-needed" As seen here, the boost library files in question are present: $ ls -l /usr/lib/*boost*mpi* -rw-r--r-- 1 root root 3127528 Nov 11 16:37 /usr/lib/libboost_mpi.a lrwxrwxrwx 1 root root 14 Nov 11 16:37 /usr/lib/libboost_mpi-mt.a -> libboost_mpi.a lrwxrwxrwx 1 root root 22 Nov 11 16:37 /usr/lib/libboost_mpi-mt.so -> libboost_mpi.so.1.46.1 lrwxrwxrwx 1 root root 22 Nov 11 16:37 /usr/lib/libboost_mpi.so -> libboost_mpi.so.1.46.1 -rw-r--r-- 1 root root 184496 Nov 11 16:37 /usr/lib/libboost_mpi.so.1.46.1 Here is the build error: [ 28%] Building CXX object tool/CMakeFiles/archive.dir/archive_xml.cpp.o cd /home/tmac/src/alps/alps-2.0.2-r5790-src/alps/obj-x86_64-linux-gnu/tool && /usr/bin/g++ -DBIND_FORTRAN_LOWERCASE_UNDERSCORE -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security -Werror=format-security -Wall -fopenmp -O3 -DNDEBUG -I/usr/include/mpich2 -I/usr/lib/pymodules/python2.7/numpy/core/include -I/usr/include/python2.7 -I/home/tmac/src/alps/alps-2.0.2-r5790-src/alps/obj-x86_64-linux-gnu/src -I/home/tmac/src/alps/alps-2.0.2-r5790-src/alps/src -o CMakeFiles/archive.dir/archive_xml.cpp.o -c /home/tmac/src/alps/alps-2.0.2-r5790-src/alps/tool/archive_xml.cpp Linking CXX executable archive cd /home/tmac/src/alps/alps-2.0.2-r5790-src/alps/obj-x86_64-linux-gnu/tool && /usr/bin/cmake -E cmake_link_script CMakeFiles/archive.dir/link.txt --verbose=1 /usr/bin/g++ -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security -Werror=format-security -Wall -fopenmp -O3 -DNDEBUG -Wl,--as-needed CMakeFiles/archive.dir/archive.cpp.o CMakeFiles/archive.dir/archive_index.cpp.o CMakeFiles/archive.dir/archive_node.cpp.o CMakeFiles/archive.dir/archive_plot.cpp.o CMakeFiles/archive.dir/archive_sqlite.cpp.o CMakeFiles/archive.dir/archive_xml.cpp.o -o archive -rdynamic -lz ../src/alps/libalps.so.2.0.2 -lsqlite3 -lz -lboost_mpi-mt -lboost_date_time-mt -lboost_filesystem-mt -lboost_program_options-mt -lboost_python -lboost_regex-mt -lboost_system-mt -lboost_serialization-mt -lboost_thread-mt -lpthread -lboost_mpi-mt -lboost_date_time-mt -lboost_filesystem-mt -lboost_program_options-mt -lboost_python -lboost_regex-mt -lboost_system-mt -lboost_serialization-mt -lboost_thread-mt -lpthread -lhdf5 -lhdf5_hl -lhdf5 -lhdf5_hl /usr/lib/python2.7/config/libpython2.7.so -lssl -lcrypto -lssl -lcrypto -L/usr/lib -lz -lpthread -ldl -lutil -lmpichcxx -lmpich -lopa -lmpl -lrt -lcr -lpthread -lmpich -lopa -lmpl -lrt -lcr -lpthread ../src/alps/libalps.so.2.0.2: undefined reference to `boost::mpi::communicator::communicator(int const&, boost::mpi::comm_create_kind)' ../src/alps/libalps.so.2.0.2: undefined reference to `boost::mpi::communicator::operator int() const' collect2: ld returned 1 exit status make[3]: *** [tool/archive] Error 1 make[3]: Leaving directory `/home/tmac/src/alps/alps-2.0.2-r5790-src/alps/obj-x86_64-linux-gnu' make[2]: *** [tool/CMakeFiles/archive.dir/all] Error 2 make[2]: Leaving directory `/home/tmac/src/alps/alps-2.0.2-r5790-src/alps/obj-x86_64-linux-gnu' make[1]: *** [all] Error 2 make[1]: Leaving directory `/home/tmac/src/alps/alps-2.0.2-r5790-src/alps/obj-x86_64-linux-gnu' make: *** [debian/stamp-makefile-build] Error 2 Any idea?

Hi! I'm trying the tutorial examples, but I always get this error message when I attempt to start a simulation. Would this be an error with a known solution?

DEPLETION
by Giuseppe Carleo 06 Dec '11

06 Dec '11

Dear all, I have installed the last stable release of the alps (2.02-r5790) but I have a problem while trying to execute standard applications : for example, when running the tutorial mc-03-magnetization/tutorial3a.py (but also other tutorials) I get the error message parsing task files ... Did not parse to end of string 'DEPLETION' I think that this issue is related to the lattice library, but I have not been able to figure out the exact origin. Any help would be really appreciated! Regards, Giuseppe Carleo

Dear Sir, Thank you very much for the mail. The possible algorithm for generating random structures is 1. Begin with known correlations of ideal crystal 2. Determine good structures to represent ideal crystal 3. Convert lattice into Ising-like model 4. Replace atoms {A,B} with spins, Sigma={-1,+1} 5. Consider a set of “figures” .Define local correlation function as the product of spins 6. Calculate lattice average by summing over symmetrically equivalent figures over all sites Goal: Generate small unit cell that reproduces the correlations found in random alloys using a MC code Thank you Suddhasattwa Ghosh On Sun, Nov 27, 2011 at 4:30 PM, < comp-phys-alps-users-request(a)lists.phys.ethz.ch> wrote: > Send Comp-phys-alps-users mailing list submissions to > comp-phys-alps-users(a)lists.phys.ethz.ch > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.phys.ethz.ch/listinfo/comp-phys-alps-users > or, via email, send a message with subject or body 'help' to > comp-phys-alps-users-request(a)lists.phys.ethz.ch > > You can reach the person managing the list at > comp-phys-alps-users-owner(a)lists.phys.ethz.ch > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Comp-phys-alps-users digest..." > > > Today's Topics: > > 1.
