QUDA is a library for performing calculations in lattice QCD on GPUs.
Hi All, I am new to QUDA and I stuck in a problem foe a while now. When running a QUDA-enabled solver via Chroma, the solver fails to converge and...
The current interface doesn't support initial guesses because of a sign convention difference between MILC and QUDA. The fix is flipping the sign on an initial guess before handing it...
Hello, When using the batched, strided, GEMM interface in Quda I get incompatible results (when batch_count > 1) with a simple for-loop cpu code and the expected result from the...
At present, QUDA has no host side verification of the GPU smearing and flow kernels. We require a host side routine that will compute the various link products and staples,...
I'm homogenising the gauge smearing and fixing routines. The addition of Wilson Flow routines to QUDA would be a nice addition.
As part of #1555 a new 4th order (6 step) flow algorithm was introduced alongside the original 3 step one. These two Runge-Kutta integrators can be merged with the correct...
`cudaMemPrefetchAsync` currently accepts either a GPU device ID for moving data to devices, or `-1` to prefetch data to the host. The newer routine `cudaMemPrefetchAsync_v2` gives more granularity over migration...
There are a few known cases (especially with Arnoldi) where the Ritz values (computed in double precision) meet the convergence criteria for the eigensolver, but the actual eigenvalues from the...
Added use_smeared_gauge to QudaInvertParam to get rid of awkward extra bool in some routines. In setDiracEigParam(...), added code to allow this to run without needing gaugePrecise having already been set....
