Sparse Parallel Robust Algorithms Library
Add support for newer NVIDIA GPUs and drop unsupported one, for details see: https://arnon.dk/matching-sm-architectures-arch-and-gencode-for-various-nvidia-cards/ This should hopefully help resolve #84
I am trying to follow the instructions at [https://gist.github.com/tasseff/ee61ef6c15d3c54e0a6b3e488f2a65be](https://gist.github.com/tasseff/ee61ef6c15d3c54e0a6b3e488f2a65be) to get IPOPT running with the GPU version of SPRAL. The CPU version works fine, but the GPU version seg faults...
In coin-or/ipopt#530, issues with running Spral SSIDS under Ipopt compiled with GCC on Windows were reported. `ssids_factor` terminates with ``` Warning from ssids_factor. Warning flag = 8 Matching-based ordering used...
I try to compile the spral/examples/C/ssids.c. I get this: gcc -o ssids ssids.c -fopenmp -O3 -lspral -lmetis -lmkl_rt -lhwloc -lgfortran -lm -lstdc++ ./ssids Current memory used: 416 bytes Maximum memory...
ssids_analyse returns with inform%flag = 0 when metis_order returns with a nonzero flag. I suspect that an extra return flag, for instance SSIDS_ERROR_NO_METIS, should be provided in datatypes.f90, and inform%flag...
Hello, I'm trying to compile Spral to use in a cluster. My installation script is the following: ################################################################################ module load $MODULE_DIR/cuda_11.3 intel/2017.4.056 openmpi/intel/2.1.1 intel/mkl/2017.4.056 git clone https://github.com/ralna/spral.git cd spral mkdir...
Please check that the indefinite GPU code as such work correctly. There are indications of unitialised memory usage (by `cuda-memcheck`'s initcheck tool) in the GPU part of the code. Also,...
The paper [here](https://arxiv.org/pdf/2106.13909.pdf) says:  We should run these test problems, replicate the segfaults, and fix the causes.
Hi, I'm following the instructions from here: https://github.com/ralna/spral/blob/master/COMPILE.md But I'm getting lots of errors like these: ``` make[1]: Entering directory '[--]/spral/build' depbase=`echo src/ssids/cpu/kernels/ldlt_app.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\ g++ -DHAVE_CONFIG_H -I. -I.....
When following the build instructions on GPU and building from a build directory: ```bash ./autogen.sh # If compiling from fresh git checkout mkdir build cd build ../configure --with-metis="-L/path/to/metis -lmetis" ```...
