Hello,
The conda forge binaries have hmat support on every platform, here using 1.12 on linux: $ python -c "import openturns as ot; print(ot.HMatrixFactory.IsAvailable())" True

Envoyé : vendredi 26 avril 2019 18:00:29 À : [email protected] Cc : STENGER Jerome Objet : [ot-users] HMAT on OpenTURNS/conda ? Hi, We are working with Jérôme on the Hmat features for kriging. However, we noticed that the binaries that come from conda-forge are not compiled with HMAT. This is revealed by the following script : import openturns as ot covModel = ot.SquaredExponential(1) myRegularGrid = ot.RegularGrid(0.0, 0.1, 100) covarianceMatrix = covModel.discretize(myRegularGrid) ot.ResourceMap_SetAsBool("HMatrix-ForceSequential", True) ot.ResourceMap_SetAsUnsignedInteger("HMatrix-MaxLeafSize", 10) hmatrixParameters = ot.HMatrixParameters() hmatrixParameters.setAssemblyEpsilon(1.e-6) hmatrixParameters.setRecompressionEpsilon(1.e-6) nuggetFactor = 1.e-5 covarianceMatrix = covModel.discretizeHMatrix(myRegularGrid,nuggetFactor,hmatrixParameters) which is partially adapted from : https://github.com/openturns/openturns/blob/master/lib/test/t_HMatrix_LU.cxx The script produces RuntimeError: NotYetImplementedException : In CovarianceModelImplementation::discretizeHMatrix, OpenTURNS had been compiled without HMat support This leads to 2 questions : ·
We used the following statement inside a kriging script and noticed that nothing changed : ResourceMap.Set("KrigingAlgorithm-LinearAlgebra",
"HMAT") This is bizarre : we might expect that the lack of HMAT support would generate an exception or a warning. Instead, the script worked fine, even though we actually did not use hmat.

Is there a way of getting OpenTURNS Anaconda binaries with HMAT enabled ? The workaround is to compile OpenTURNS, but this is inconvenient for many users. Best regards, Michaël Michaël BAUDIN 6, quai Watier
