Running spinmc application in parallel ALPS (Conda)

Hello. I've installed ALPS with conda, following these instructions: http://alps.comp-phys.org/mediawiki/index.php/Installing_via_Conda_installer Basically I've created the alps environment and installed it with the following command: conda create -n alps -c conda-forge alps It installs alps 2.3.0 py27_blas_openblas_5 and all the dependencies. Well, here the problems started... - Problem number one: When I try to run the tutorial MC-01 Autocorrelations I received a lot of errors related with HDF5, as shown below: Halted Simulation 1 HDF5 error: -1 #0 H5D.c line 145 in H5Dcreate2(): unable to create dataset #1 H5Dint.c line 490 in H5D__create_named(): unable to create and link to dataset #2 H5L.c line 1695 in H5L_link_object(): unable to create new link to object #3 H5L.c line 1939 in H5L_create_real(): can't insert link #4 H5Gtraverse.c line 867 in H5G_traverse(): internal path traversal failed #5 H5Gtraverse.c line 639 in H5G_traverse_real(): traversal operator failed #6 H5L.c line 1731 in H5L_link_cb(): name already exists Well, searching in the conda-forge I was able to check if another version of alps was available... So, I decided to install the alps 2.3.0 py27_blas_openblas_4 and it solved my problem with HDF5. With alps 2.3.0 py27_blas_openblas_4 version installed in the conda environment I can run the MC-01 Autocorrelations tutorial with no errors, but... - Problem number two At the documentation of the MC-01 Autocorrelations tutorial (and others) it says if I want to run in parallel, using MPI, all I need to do is run the following command: mpirun -np 8 spinmc --mpi --Tmin 10 --write-xml parm1a.in.xml But when I try to run (in my case -np 2) it returns the following messages: This program has not been compiled for use with MPI This program has not been compiled for use with MPI When I ran it with the command: spinmc --Tmin 10 --write-xml parm1a.in.xml it says: using the ALPS parallelizing scheduler copyright (c) 1994-2006 by Matthias Troyer <troyer(a)comp-phys.org>. see Lecture Notes in Computer Science, Vol. 1505, p. 191 (1998). But it seems not be the true Remembering, I've installed ALPS with Conda in Ubuntu 20.04 because the C/C++ compiler in my Ubuntu (version 9.3.0) does not compile ALPS sources, it generates a lot of errors. My question... is there a method to really run spinmc in parallel using ALPS Conda installation?

Dear Sharareh Sayyad alps + Z2 symmetry need to compile the source. An installation note can be found in the following page. https://www.jianshu.com/p/ae62c96d3224 I wish this note may be helpful. Good luck.

I have tried to change my compiler by varying "CMAKE_CXX_FLAGS" but couldn't push the installation any further. I have attached the "CMakeCache.txt" for reference. Do you have any suggestions on making changes on either Conda or Port installation so that my code with Z2 symmetry starts working? Best regards, Sharareh Sayyad
