The serial assembly conjecture for sparse Cholesky methods
The methods LL, RL, and MF are compared on large sparse matrices using serial and multithreaded BLAS. Their assembly operations are performed serially, whereas RLB performs every f…

Conjecture on maximum ranks degrading factorization performance in larger test cases
In the reported hierarchical high-order CFD solver experiments, the matrix ranks vary across the computational domain, with larger test cases exhibiting relatively high maximum ran…

Conjecture on approximately constant coded throughput for polar codes
Throughput conjecture. The coded throughput will remain approximately the same for any polar code, as the PCIe link is saturated and data transfer is the bottleneck.
