Making the scheduler switch tasks, obtaining MPI rank
by Peter Bröcker 19 Sep '13

19 Sep '13

Hello, I am using the ALPS libraries for scheduling and observable handling. I typically have more tasks than cores, especially when debugging on my personal computer. Is it possible to make the scheduler start say the first four jobs and when it's time to write a checkpoint switch to the next four instead of continuing with the first until they are finished? Also for debugging purposes, I print out some messages along the way and it would help to know which process printed them. Is the MPI rank saved somewhere or do I have to obtain it myself? Best regards, Peter

Re: [ALPS-users] Time propagation in TEBD stops prematurely
by Joseph Prentice 18 Sep '13

18 Sep '13

Hi Michael, Unfortunately, the fix you suggested, deleting one of my quenches, only worked for a little bit (although I had to change it a little, by making POW 1 instead of 0 - otherwise the quench did not occur at all). As I've increased Chi up to around 800, I've encountered the same issue as before - namely that the program just stops at around t=5 in the real time propagation when it should continue to t=15, with no error message at all. The parameters of my new Python script, incorporating the suggestion from before is below. Is there anything else I can do? I'm running on a Linux cluster. Any help would be brilliant. Thank you very much, Joseph Python script parameters: parms = [ { 'L' : 128, 'MODEL' : 'spin', 'local_S' : 0.5, 'CONSERVED_QUANTUMNUMBERS' : 'Sz', 'Sz' : 0, 'Jxy' : 1, 'Jz' : 3.0, 'ITP_CHIS' : [80, 80], 'ITP_DTS' : [0.05, 0.025], 'ITP_CONVS' : [1E-10, 1E-11], 'INITIAL_STATE' : 'ground', 'CHI_LIMIT' : 800, 'TRUNC_LIMIT' : 1E-12, 'NUM_THREADS' : 1, 'TAUS' : [15.0], 'POWS' : [1.0], 'GS' : ['Jz'], 'GIS' : [6.0], 'GFS' : [6.0], 'NUMSTEPS' : [625], 'STEPSFORSTORE' : [10], 'VERBOSE' : 'true' } ] On 22 Aug 2013, at 11:00, <comp-phys-alps-users-request(a)lists.phys.ethz.ch> <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.

Hi Michael, sorry I've been slow on the reply, I didn't see this response. Thank you very much, this seems to have worked! My code had worked for lower Chi values, but when I increased the Chi value beyond a certain point, I experienced the problem I mentioned. Thank you for solving it!

[ALPS-user] Simulate fermion Hubbard using dirloop_sse
by Tao Ying 08 Sep '13

08 Sep '13

Dear developers, I want to simulate the fermion Hubbard model using dirloop_sse, how can I write the parameter file? I did the following: LATTICE="square lattice"; L=8; W=8; MODEL="fermion Hubbard"; U = 5.0; V = 0.0; t = 1.0; T = 0.05; SWEEPS=2000; THERMALIZATION=5000; { mu=0.0; } Then an error occured: Cannot convert fermionic operator to a bosonic matrix. What's wrong with it? If I want to measure the structure factor or correlation function, do I need to add the following in the parameter file? REPRESENTATION="SSE"; MEASURE[Correlations]=true; MEASURE[Structure Factor]=true; MEASURE[Green Function]=true; Best, TaoYing -- Tao Ying, Ph.D candidate, Physics department Harbin Institute of Technology

Parallel ALPS (using python) jobs via SLURM
by Scott Garland 05 Sep '13

05 Sep '13

I'm attempting to execute tutorial3a.py in the mc-03-magnetization directory using MPI. I'm using a cluster running Ubuntu Server 12.04 LTS and using the SLURM queue manager. I have run it successfully in serial by submitting it to nodes via SLURM. I have also successfully run it in serial without SLURM. When running in serial, I find the following line of code inside the .py file. res = pyalps.runApplication('dirloop_sse',input_file,Tmin=5,writexml=True) According to the ALPS tutorial webpage, the simulation can be run in parallel by simply changing the line above to res = pyalps.runApplication('dirloop_sse',input_file,Tmin=5,writexml=True,MPI=4) All I have done is appended "MPI=4" as an argument. This generates the following output when run with or without SLURM: parsing task files ... Creating a new simulation: 1 on 1 processes Created run 1 locally All processes have been assigned NUMBER_OF_WORMS_PER_SWEEP: 39 Checking if Simulation 1 is finished: Finished Halted Simulation 1 WARNING: Unclosed tag: SIMULATION! boost::filesystem::rename: No such file or directory: "/home/sgarland/moreTutorials/alps/mc-03-magnetization/outputFolder/output.task1.out.run1.h5.bak", "/home/sgarland/moreTutorials/alps/mc-03-magnetization/outputFolder/output.task1.out.run1.h5" -------------------------------------------------------------------------- MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD with errorcode -2. NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes. You may or may not see output from other processes, depending on exactly when Open MPI kills them. Does anyone have any suggestions regarding this issue? I have tried both defining and not defining the number of cores for SLURM to allocate, but haven't had any luck. Thanks! Chad Garland

problem with ngs.py
by Borghi Giovanni 02 Sep '13

02 Sep '13

Dear Alps staff, I downloaded Alps in order to use the maximum entropy code for some analytic continuations, and wanted to start understanding it by using the script by Pruschke, found in a previous post, https://lists.phys.ethz.ch/pipermail/comp-phys-alps-users/2013/001978.html So after installing alps from source, using package alps-2.1.1-r6176-src-with-boost and following the instructions (I installed it on a linux machine with Ubuntu)... .. I performed the tutorial dmft-04-mott/tutorial4a.py, to produce a sample imaginary time Green's function data, and afterwards, from ipython, tried to follow some of the instructions of Pruschke's script, quoting from that script: "from pyalps.ngs import h5ar # hdf5 interface" this produced the error message: >/opt/alps/lib/pyalps/ngs.py in <module>() > 29 import types > 30 >---> 31 from pyngsparams_c import * > 32 params.__bases__ = (MutableMapping, ) + params.__bases__ > 33 ImportError: No module named pyngsparams_c And indeed I could not find any such module in the source. My question is: what is going on? Did I miss to install some pre-requisite? Note that the tutorial simulation for the hubbard model works fine till the end, same thing can be said for all tests which I ran before installing the code in its /opt/alps path. Thank you in advance for your help, Giovanni

Thanks for looking into it! I tried the newest SVN version 6991 and except for one thing everything went smoothly. My last problem is resolved now. I encountered the following error on compilation: During cmake, I got: CMake Error at applications/qmc/dwa/CMakeLists.txt:27 (install): install TARGETS given target "worldlines_c.so" which does not exist in this directory. I commented out the lines mentioned above, since I don't need it and compilation continued successfully. best wishes, Steffen > Steffen, > > it seems that the hybridization3 code was not deemed important enough to > make it into the 2.1 branch.

Do I have to change something in my parm.h5 input file for this new version? Thanks for your help. Best wishes, Steffen
