Core parallelization and GPU porting
by degliesposti 03 Dec '10

03 Dec '10

Dear ALPS users, I wonder if some of you is experienced and could give us recent insights about these two points: i) core parallelization with ALPS: which parallel environment is better (OpenMP, MPICH, ...) ii) are there any porting/tests of ALPS on GPU's ? Thanks for your time, Cristian Degli Esposti Boschi

Questions regarding DMRG
by Chong You Quan 03 Dec '10

03 Dec '10

Hi, I'm using ALPS 1.3.5 on Linux currently. I'm new to ALPS and DMRG and I'd just like to clarify a few questions:1. For full DMRG application with verbose = 1 using the Heisenberg (spin) model, what is the basis of the RHO's eigenvalues in the output? DMRG truncates the density matrix, so, the basis of the density matrix is that of the spin sites is it? For example, L = 2, then the basis would be |00>, |01>, |10>, |11>.. is it correct? What about the basis of the matrix after truncation? Also, if I would like to get the full wavefunction in the basis of the sites, what should I do? Also if I specify that N is conserved, what is the default value of N? Or does it try all possible N to give the lowest energy state?2. I can see that ALPS can be integrated into C++ but I tried googling for examples and documentation to no avail.. Is it in the Trac wiki? If so, must one register for it in order to view the documentation? The default documentation seems to specify what the input valu es represent but don't describe much of the output or how to integrate ALPS into C++.. Am I missing out on some way I can find the documentation for ALPS and how to integrate it in C++?3. I noticed there were some .dat files after running the DMRG application.. Are those temporary files stored during calculation or are those actual output files? I didn't seem to be able to extract any form of data from those files.. Is it that all the useful output for the DMRG is written to the screen?4. I'm not sure why but my parameter2xml does not seem to work on any of the example parameter files.. I'm currently just typing out the xml file by hand. Maybe I'm just missing out on something.. Does parameter2xml output to a specific directory or something?5. Almost all of the files on http://www.comp-phys.org/lugano04/Talks.html seem to be broken.. Is it that the links are outdated or something? I'm sorry if some of these questions sound too amateur but this seems to be the best place I can find an answer to these questions.Thanks in advance. Regards,YQ

Re: [ALPS-users] ALPS linux binary packages in repositories?

ALPS linux binary packages in repositories?
by Krunoslav Prsa 30 Nov '10

30 Nov '10

Dear ALPS developers, I have a simple question. Are ALPS binary packages available for download/automatic update through standard Ubuntu/Debian repositories? This appears to be the main argument of the clusters' system administrators against requests to install alps libraries and applications. They claim that it is not possible and that it involves extra work for them to update it manually (which they are not paid for). I also cannot seem to find it in packages.debian.org and packages.ubuntu.com. There are only some old binaries for Ubuntu 6.06 Dapper Drake. The manual installation of ALPS on a cluster without administration privileges is difficult. This needs to be said, although I understand that you are continuously doing steps to make it easier. I think that many end users would appreciate having a standardized way of installing and updating the packages through the repositories. Please note that all this is written bona fide (from a happy ALPS user) and assuming, of course, that this issue is not already resolved. Best wishes and thanks in advance, Kruno ------------------------------------------------- Dr. Krunoslav Prsa, Postdoc Dynamics of strongly correlated materials Lab. for Solid State Physics Building/Office: HPF/E15.1 Schafmattstrasse 16, ETH Zürich Hönggerberg, CH-8093 Switzerland.

ALPS 2.0.0rc2 binary packages for Debian (amd64)
by Ryo IGARASHI 25 Nov '10

25 Nov '10

Hi, I have created binary packages of ALPS 2.0.0rc2 for Debian GNU/Linux (primary for sid(unstable), but should work also on squeeze(testing)). The apt line is as follows: deb http://alps.comp-phys.org/static/software/debian/sid ./ deb-src http://alps.comp-phys.org/static/software/debian/sid ./ Currently, I have only compiled amd64 packages. I can run python-based tutorials with these binary packages[1][2], but if you find any bugs related to debian packaging, please open the trac ticket and assign to me(rigarash) or just report to the ML. [1] Since all binaries/scripts are installed system-wide, use 'python' instead of 'alpspython'. [2] This package does not contain dirloop-sse binary because of the incompatibility of lpsolve library.

"fulldiag": Can it handle magnetic field coupled to a non-conserved quantity?
by Itamar Kimchi 24 Nov '10

24 Nov '10

Hi all, I'm new to ALPS, but before I try to learn how to use it, I wanted to resolve an ambiguity in the documentation to figure out whether it's applicable to my problem. I want to find the magnetic susceptibility for a spin system, where the magnetic field h couples to Sz_tot as usual. However, I wish to use a Hamiltonian that does not commute with Sz_tot, hence does not leave it conserved. In the fulldiag "documentation" file http://alps.comp-phys.org/mediawiki/index.php/Documentation:FullDiagonaliza… there is a red warning claiming that I cannot use fulldiag if Sz_tot is not conserved. However, this documentation looks like it's two years old. The new tutorial, at http://alps.comp-phys.org/mediawiki/index.php/ALPS_2_Tutorials:ED-06_FullDi… has no such warning, but it only gives an example for calculating the susceptibility for a Heisenberg Hamiltonian, which conserves Sz_tot. Do you know if I can use fulldiag (or anything else) if my Sz_tot is not conserved? Thanks! Itamar

asking for help
by Xiao Quan Yu 23 Nov '10

23 Nov '10

Dear ALPS community, We are trying to use SSE to study 3D BoseGlass, our input file is the following: LATTICE_LIBRARY="lattices.xml"; LATTICE="inhomogeneous simple cubic lattice"; L=2; W=2; H=2; MODEL_LIBRARY="models.xml"; MODEL="hardcore boson"; t = 1.0; T = 0.2; SWEEPS=500000; THERMALIZATION=10000; {DISORDERSEED = 34275; mu=delta*2*(random()-0.5);} {delta=0.0} {delta=1.0} {delta=2.0} {delta=3.0} {delta=4.0} {delta=5.0} . The "parameter2xml input" step is fine, but after doing "dirloop_sse ", it says"too many positional options". We do know how to solve this problem. We also tried the example of 2D BoseGlass model in the ALPS wiki webpage, the code of worm algorithm is LATTICE_LIBRARY="../lattices.xml"; LATTICE="inhomogeneous square lattice"; L=4; MODEL_LIBRARY="../models.xml"; MODEL="boson Hubbard"; NONLOCAL=0; U = 1.0; Nmax = 2; t = 1.0; T = 0.1; delta = 5.0; SWEEPS=500000; THERMALIZATION=10000; { DISORDERSEED = 34275; mu=delta*2*(random()-0.5); } { DISORDERSEED = 49802; mu=delta*2*(random()-0.5); } { DISORDERSEED = 82529; mu=delta*2*(random()-0.5); } , we just use the same code but for SSE, and meet the same "too many positional options" problem. It seems one should modify the input file, but we don't know how. Thank you in advance.
