sparse matricesworkstation clusters/ parallel sparse CGM solverCFD computationsIn this study we introduce strategies for a load-balanced parallelization of sparse matrix computations on a cluster of PCs with minimum communication overhead. Based on these strategies a parallel sparse Conjugate Gradient ...

CLUSTER_SPARSE_SOLVER segmentation fault Subscribe More actions Oleg_S_ Beginner 04-21-2019 07:07 AM 2,305 Views Hi all! I am getting forrtl: severe (174): SIGSEGV, segmentation fault occurred during factorization step of CPARDISO. It happens when i try to solve Nonsymmetric ...
The symbolic analysis seems to work fine, but the subsequent cluster_sparse_solver call with phase = 22 (for numerical factorization) crashes. The platform is windows, and we build it with 64-bit indexing (ilp64) Thanks in advance for looking! ...
How is the feature iparm(2) = 10 supposed to work with cluster_sparse_solver? If I adapt cl_solver_unsym_distr_c.c by changing the value of iparm[ 1] to 10, with 2 processes, it hangs on both Linux with IntelMPI and macOS with MPICH, and it segfaults ...
Hello, I'm trying to use cluster_sparse_solver and solve a system in-place (iparm(6) = 1), with a distributed format (iparm(40) = 1). I adapted the
