We found the following problems when trying to compile the code under linux: 1. The folder "lib" is not created when calling make. It was necessary to create this folder...
Dear developer, I found that cudasetdevice () is not included in your source code. Does that mean that multi card is not supported. If so, what adjustments do I need...
The SuperLU_DIST is build by cmake and tests are run as: `export ARGS="$ARGS --tests-regex pdtest_[12]x1_[13]_2_8_20_SP" && make test` which results in this call: `ctest --force-new-ctest-process --tests-regex pdtest_[12]x1_[13]_2_8_20_SP` *pdtest_1x1_1_2_8_20_SP* and *pdtest_1x1_3_2_8_20_SP*...
I am applying SuperLU_MT (version 3.1) which is supported by Amesos2 to calculate preconditioner. It is found that the SuperLU_MT has great parallel performance in LU decomposition. However, when I...
Hello, We are trying to solve 66,000x66,000 matrix with 400,000 nonzero elements (approximate dimensions). This matrix is symmetric, with its lower right block being entirely zero (of approx. 33000x33000 size)....
CXXFLAGS not defined. After defined still not compiled. Ubuntu 16.04
I have built SuperLU_DIST with GPU acceleration enabled, by setting `-DGPU_ACC` and adding `cublas_utils.c` to the build. However, after doing so, `make test` no longer terminates.
Build fails with openmpi 4.0: ``` mpicc -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mcpu=power8 -mtune=power8 -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mcpu=power8...
I want to solve the tridiagonal Ax=b with superlu_dist. Does superlu_dist has a special function to treat the tridiagonal A.
Hi, I have been using superlu_dist to solve a complex-valued block-tridiagonal linear system that arises from discretizing a 2D variable coefficient Poisson equation using 2nd order central difference scheme for...
