Hello, Sometimes QMC worm code (used on Bose-Hubbard) terminates with the following error: here come first earlier succesful simulations then ... Created run 85 remote on Host ID: 84 Created run 86 remote on Host ID: 85 Created run 87 remote on Host ID: 86 Created run 88 remote on Host ID: 87 All processes have been assigned Checking if Simulation 1 is finished: not yet, next check in 120 seconds ( 0% done). q = -0 state1 = 0 state2 = 0 bond_type = 0 zero matrix element in remove_jump application called MPI_Abort(MPI_COMM_WORLD, -2) - process 67 Could somebody advice what I can do?

Problem in ALPS 2.0b4 which does not occur in ALPS 1.3.3
by Urs Gerber ITP 25 Oct '10

25 Oct '10

**I am using ALPS 2.0b4 by simulating bilayer spin-1/2 Heisenberg model in an uniform magnetic field on the square lattice using dirloop_sse. It is strange that some runs are killed automatically without producing any output file. For example, for lattice size L = 12, the run with \beta = 24 goes smoothly to the end, but the run using \beta = 48 is killed. This also happens for other lattice sizes when beta gets too large. I will be grateful if anyone can help me with this. U.G.

Example of how to run ALPS applications from Maple
by Andriy Zhugayevych 25 Oct '10

25 Oct '10

On my web-page http://zhugayevych.me/maple/index.htm you will find a Maple worksheet example of sparse diagonalization in ALPS 2.0 for Windows. The direct links are: http://zhugayevych.me/maple/ALPS_example.mw (Maple worksheet only) and http://zhugayevych.me/maple/ALPS.zip (whole working folder). If you will find an easier or more efficient way to run ALPS applications from Maple, please, let me know. Best regards, Andriy Zhugayevych

ALPS 2 compilation on AIX

21 Oct '10

Dear Matthias, we've made again some progress with ALPS 2 b 3 compilation. Now it stops on test compilation with the following messages, it looks like a compiler bug similar to the previous one found for examples, so I'm going to turn off building tests, too. Is it OK ? Let me know please if you need the log files. Thank you again for your help Best Jessica These are the messages: [ 72%] Building CXX object test/alea/CMakeFiles/detailedbinning.dir/detailedbinning.C.o cd /gpfs/scratch/userinternal/cin8337a/build/alps-2.0.0b3-r4750-src-with-boost/test/alea && /usr/bin/mpCC_r -+ -DBOOST_ALL_NO_LIB=1 -DBOOST_ALL_DYN_LINK=1 -qmaxmem=-1 -DBIND_FORTRAN_LOWERCASE -qsmp -O -DNDEBUG -I/cineca/prod/libraries/hdf5/1.8.4_ser/xl--10.1/include -I/gpfs/scratch/userinternal/cin8337a/build/alps-2.0.0b3-r4750-src-with-boost/src -I/gpfs/scratch/userinternal/cin8337a/build/alps-2.0.0b3-r4750-src-with-boost/alps/src -I/gpfs/scratch/userinternal/cin8337a/build/alps-2.0.0b3-r4750-src-with-boost/boost -o CMakeFiles/detailedbinning.dir/detailedbinning.C.o -c /gpfs/scratch/userinternal/cin8337a/build/alps-2.0.0b3-r4750-src-with-boost/alps/test/alea/detailedbinning.C make[2]: Leaving directory `/gpfs/scratch/userinternal/cin8337a/build/alps-2.0.0b3-r4750-src-with-boost' make[1]: Leaving directory `/gpfs/scratch/userinternal/cin8337a/build/alps-2.0.0b3-r4750-src-with-boost' the reported error is: "/gpfs/scratch/userinternal/cin8337a/build/alps-2.0.0b3-r4750-src-with-boost/alps/test/alea/detailedbinning.C", line 91.27: 1540-1228 (I) Argument number 2 is an lvalue of type "alps::RealObsevaluator".

successful ALPS 2 beta 3 on AIX
by jessica.alfonsi＠unipd.it 21 Oct '10

21 Oct '10

Dear Matthias, I'd like to inform you that we've just had a successful installation of ALPS 2 beta 3 on AIX after turning off examples. At the moment the build of applications is turned off, since I needed a very basic configuration for compiling my code. We're going to try soon with build applications on and I'll let you know if there are any issues again. Then we'll try more recent revisions of ALPS. Thank you very much again for your support. Best regards Jessica

Dear Jessica, Once it works I would like to collect all the changes you needed to make to the sources, so that we can include them directly in the final ALPS 2.0 release Matthias On 14 Oct 2010, at 00:43, jessica.alfonsi(a)unipd.it wrote: > Thank you very much Prof. Troyer, you're simply the best !! > Jessica > On Gio, 14 Ottobre 2010 9:40 am, Matthias Troyer wrote: >> Hi Jessica, >> >> These are functions in the Fortran runtime libraries that need to be >> linked to Lapack.

problem with worm algorithm
by Jakub Kolasinski 18 Oct '10

18 Oct '10

Hi, I have encountered problem with worm algorithm, and I would be very grateful for help. I'm using ALPS 1.3.4, and the problem is as follows. In low temperatures (around 0.05 with U=1) and hopping parameter around 0.2 simulation runs normally and then just stops - but there is no error. So it seems to be everything ok, simulation status is "running" - but there is no progress. If I rerun the simulation on the same parameters few times, it eventually works to the end. Problem intesifies with growing hopping parameter J - for J=0.1 this problem happens very rarely to me. I would really appreciate any help. Best regards Jakub Kolasinski

Hello, after trying your last suggestion there are new error messages related to xlf stuff. I've sent you an e-mail with the attached log and CMakeCache.txt files for inspection. Could you please have a look at it ? Thank you. Sincerely, Jessica

Dear Prof. Troyer, did you receive the log file of the make VERBOSE=ON related to the Lapack linking problem of ALPS 2 on AIX ? Do you have any solution for that ? Is there some compiler option which I could try ? Thank you for your help. Best Jessica
