Dear Alps users
I am trying to do a QMC simulation of the J1-J2-model on the s=1
rectangular lattice using the "dirloop_sse" app. I am fairly new to using
Alps, so I was wondering if someone would verify that my input parameters
are correct. My parameter files contains:

<?xml-stylesheet type="text/xsl" href="ALPS.xsl"?>
<SIMULATION xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Hi,
I am Probal Nag, a research scholar from IISER-Thiruvananthapuram. I am
currently trying to install ALPS on Windows system by following the
document on installing the binary releases on Windows.
I have downloaded alps-2.2.b3 for windows followed by the
required aps-vistrails module from the download page and also Vistrails
2.1.2.
However, after installation, while trying to activate the ALPS module from
the preference, I face an error while enabling alps. I get the error
Critical message:…

Module Tools|MplXYPlotCell in package org.comp-phys.alps (version 2.2.0) is
out-of-date. Please check with the package developer for a new version.
I will be extremely grateful to you if you could help me out.

Dear Alps users
I am completely new to using Alps; I have just tried to run some tutorials
from the wiki page using python. However, even that proved to be more
difficult than expected.
My problem is that the output file(s) from the simulation seem to be empty.
I succeed in setting up the tutorial and it starts running, but crashes
quickly. The problem comes when running tutorial-full.py. See error message
below:

I also tried running tutorial2c.py, a simulation of the susceptibility of a
quantum spin chain. The program runs (very quickly) and then plots an empty
graph - again the problem is that the output file "parm2c.out.xml" is
completely empty.
I hope some of you can pinpoint the problem and help me run these tutorials
successfully.

Hi all,
I've recently created an ALPS package within Spack, an HPC package manager.
Spack enables building ALPS and all its dependencies from scratch with a
single line of command. Furthermore, Spack automatically optimizes the
build (vectorisation etc) for the CPU architectures of interest. I thought
some of you might be interested to check it out, also it might be useful to
list it under the installation methods page of ALPS wiki.
$ git clone https://github.com/spack/spack.git
$ cd spack/…
[View More]bin
$ ./spack install alps
$ ./spack load alps
Alps doesn't build with gcc =>7, so if the default compiler on your system
satisfies that, you might also want to install an older version of gcc in
your system or just build it from scratch with Spack (which might take up
to a few hours)
$ ./spack install gcc(a)6.5.0
$ ./spack load gcc(a)6.5.0
$ ./spack compiler find
$ ./spack install alps%gcc(a)6.5.0
Hope some of you will find this useful.
