Modifying input in the DMRG program
by Christopher Brust 16 Feb '07

16 Feb '07

Hi. I'm a student doing research on Heisenberg spin chains, and I'm attempting to get ground state energies for longer chains than my group has done before. I've been running the DMRG program included with ALPS (not the 'simple' one) with a parameter file that looks something like: MODEL = "spin" LATTICE = "chain lattice" LATTICE_LIBRARY = "../lattices.xml" MODEL_LIBRARY = "../models.xml" CONSERVED_QUANTUMNUMBERS = "Sz" local_S = 1/2 J = 1 V = 0 SWEEPS = 30 MAXSTATES = 60 OUTPUT_LEVEL = 1 {L = 30} I've been able to successfully run the program, though I'm not entirely sure that all the parameters I've specified are the right ones (and that it's not just reverting to the defaults). I've been unable to find any documentation on how this particular implementation of the program works, so can anyone tell me if I'm off to the right start? In addition, I'd like to be able to run this program with site-dependent interaction coefficients (such as J = 3*k) or so, but after much tinkering, I've been unable to find the variable 'k' that represents position on the lattice. My question is is this even possible? If so, how? Should I instead be trying to modify the source code for the program and recompile it? Thanks for your time.

Run-time errors in simple_dmrg
by Christopher Dawson 18 Jan '07

18 Jan '07

Hi there, I recently compiled alps-1.3b3 (and the applications) with boost version 1.33.1. On running simple_dmrg < parm1, as in the tutorial, I get the following error EXCEPTION: bad lexical cast: source type value could not be interpreted as target I can't figure out where this exception is being thrown, has anyone experienced this error before? Kind regards. Chris

A question about installing the libraries.
by Javier Vijande 15 Jan '07

15 Jan '07

Hi. I am trying to compile for the first time the libraries and program of ALPS, so probably this is a very silly question. I am having difficulties making the program to recognize the BLAS and LAPACK libraries. I install the BLAS and LAPACK libraries that are in http://www.netlib.org/blas/ http://www.netlib.org/lapack/ These are f77 libraries I normally use, so I am quite sure they are properly installed (at least they never were a problem until now). After they are installed I copy the .a file into the usual /usr/lib and also to be sure into the ~/home/vijande/ALPS/lib folder and I try to make the instalation of the .configure tool of the instalation with the following options: ./configure --prefix=/home/vijande/ALPS --with-lp_solve=/home/vijande/Fortran/BEC/lp_solve_4.0 --with-blas-lib=/home/vijande/ALPS/lib --with-blas=-lblas --with-lapack-dir=/home/vijande/ALPS/lib --with-lapack=-llapack and I obtain the following error message: configure: checking for ESSL on IBM AIX checking for dgemm_ in -lessl... no configure: checking for ATLAS Library checking for dgemm_ in -latlas... no checking for dgemm_ in -L/home/vijande/ALPS/lib -latlas... no checking for dgemm_ in -L/usr/local/lib -latlas... no checking for dgemm_ in -lf77blas -latlas... no checking for dgemm_ in -L/home/vijande/ALPS/lib -lf77blas -latlas... no checking for dgemm_ in -L/usr/local/lib -lf77blas -latlas... no checking for dgemm_ in -lf77blas -latlas -lg2c... no checking for dgemm_ in -L/home/vijande/ALPS/lib -lf77blas -latlas -lg2c... no checking for dgemm_ in -L/usr/local/lib -lf77blas -latlas -lg2c... no checking for dgemm_ in -lf77blas -latlas -lI77 -lF77... no checking for dgemm_ in -L/home/vijande/ALPS/lib -lf77blas -latlas -lI77 -lF77... no checking for dgemm_ in -L/usr/local/lib -lf77blas -latlas -lI77 -lF77... no configure: checking for BLAS Library checking for dgemm_ in -lblas... no checking for dgemm_ in -lblas... no checking for dgemm_ in -L/home/vijande/ALPS/lib -lblas... no checking for dgemm_ in -L/usr/local/lib -lblas... no checking for dgemm_ in -lblas -lf2c... no checking for dgemm_ in -L/home/vijande/ALPS/lib -lblas -lf2c... no checking for dgemm_ in -L/usr/local/lib -lblas -lf2c... no checking for dgemm_ in -lblas -lg2c... no checking for dgemm_ in -L/home/vijande/ALPS/lib -lblas -lg2c... no checking for dgemm_ in -L/usr/local/lib -lblas -lg2c... no checking for dgemm_ in -lblas -lpgftnrtl -lpgc... no checking for dgemm_ in -L/home/vijande/ALPS/lib -lblas -lpgftnrtl -lpgc... no checking for dgemm_ in -L/usr/local/lib -lblas -lpgftnrtl -lpgc... no configure: disabling BLAS support configure: disabling LAPACK support configure: LAPACK library not found. diag/fulldiag will not be built. configure: LAPACK library not found. diag/sparsediag will not be built. configure: LAPACK library not found. dmrg/particle_in_box will not be built. configure: LAPACK library not found. dmrg/interacting will not be built. configure: LAPACK library not found. qmc/looper will not be built.

make install for ALPS-1.3b3

I'm having trouble with make install for ALPS-1.3b3. I'm running OS X 10.4.8 on a PowerPC Powerbook. ALPS is in HOME/alps-1.3b3. Boost (version 1.33.1) is in HOME/ alps-1.3b3/boost.

Question about failed tests (example3, example4, example8)

Dear ALPS users, I'm trying to get started with ALPS, and I would like to ask if you have a suggestion concerning the following two test failures I encountered. I have a hunch they may be related to my particular choice of Linux/Compilers but maybe you have seen them before. My setup: $ more /etc/fedora-release Fedora Core release 5 (Bordeaux) $ uname -a Linux caiman 2.6.15-1.2054_FC5 #1 SMP Tue Mar 14 15:48:20 EST 2006 x86_64 x86_64 x86_64 GNU/Linux $ which icc /opt/intel/cce/9.1.044/bin/icc $ ls -l /opt/intel/mkl/8.1.1/lib/em64t/libmkl_lapack.a -r--r--r-- 1 root root 14955956 Aug 11 08:34 /opt/intel/mkl/8.1.1/lib/em64t/libmkl_lapack.a Now I get the following: $ cd ./alps-1.3b3/test/model/ $ ./example3 HHardcoreBosonSite = *** glibc detected *** /home/jeschke/alps-1.3b3/test/model/.libs/lt-example3: double free or corruption (out): 0x00002ab9377db010 *** ======= Backtrace: ========= /lib64/libc.so.6[0x3af126d7a3] /lib64/libc.so.6(__libc_free+0x84)[0x3af126d924] /home/jeschke/alps-1.3b3/test/model/.libs/lt-example3[0x421c2e] /home/jeschke/alps-1.3b3/test/model/.libs/lt-example3(__gxx_personality_v0+0x2a4)[0x41129c] /lib64/libc.so.6(__libc_start_main+0xf4)[0x3af121d084] /home/jeschke/alps-1.3b3/test/model/.libs/lt-example3(_ZNSt8ios_base4InitD1Ev+0x41)[0x411099] ======= Memory map: ======== [if helpful I can send the memory map also.] I compiled a version of example3 with -g and ran it in idb; I then get a signal SEGV in /home/jeschke/alps-1.3b3/src/alps/model/siteoperator.h line 180 mat[i][j].second=false; with i=1 and j=32781 which is called from the same file, line 130 boost::multi_array<T,2> matrix(boost::extents[f_matrix.shape()[0]][f_matrix.shape()[1]]); which is called from example3.C line 50 std::cout << "HHardcoreBosonSite =\n" << alps::get_matrix(Expression_(),lib.get_hamiltonian("hardcore boson",p,true).site_term(), lib.get_hamiltonian("hardcore boson").basis().site_basis()) << "\n"; The other problem (identical for example4 and example8): $ ./example4 HHardcoreBoson = Caught exception: St9bad_alloc This seems to occur in example4.C line 79 std::cout << "HHardcoreBoson = \n" << bondmatrix(lib,"hardcore boson") << "\n\n"; but I haven't been able to trace it further.

Plot file problems
by Austen Lamacraft 06 Dec '06

06 Dec '06

An elementary question from a beginner user... I can't get the simplest plot file examples given in the ToolsHOWTO or Tutorial:ClassicalMCSimulations to work. While extracttext, extractxmgr and direct evaluation using xsltproc all work without complaining , no points are extracted e.g. from the task files produced by the one-dimensional Heisenberg simulation in Tutorial:ClassicalMCSimulations. Thus although the plots produced by extractxmgr plot.xml parm2a.task*.out.xml > result.xmgr are correctly labeled, there are no points. Any ideas? Thanks, Austen

Hamiltonian Matrix Elements
by Jeff Hammond 04 Dec '06

04 Dec '06

Dear ALPS friends, I'm trying to generate Hamiltonian matrix elements for lattice models using the kitchen sink of symmetries in ALPS. Unfortunately, I can't figure out where I can get them by reading the source code. Specifically, I'm looking for the quantity M(i,j,k,l) which defines the Hamiltonian H = sum(i,j,k,l) M(i,j,k,l) c(i)+ c(j)+ c(l) c(k). I doubt it is ever stored complete in memory, but I just want to read it out element-by-element in sparse format into an external file. If no part of this quantity ever exists but can be obtained by some modifying the code, that works, too. If someone can point me to the right place and make a suggestion for what to do, that would be fantastic. If this is not a simple request at all, but someone still wants to help me, I can give a much more detailed explanation of what I'm trying to do. Jeff Hammond The University of Chicago
