We are porting a cuda library `quda` to ROCm platform, in which `hipIpcOpenEventHandle` and `hipIpcGetEventHandle` are used. However I did not find any useful message about them. Does HIP support the…

The full clover packers from Twisted-Mass don't have pack functions
```qdp_pack_full_clover()```
in ```qdp_packer_qdpjit.h```
This prevents the RandomGauge utility from being built and with i…

The link unitarization has one of the largest performance regressions when running on Maxwell, which doesn't have fast double-precision capability. Benchmarking reveals that the bulk of the time is s…

In dee6b93956ef94862dbfd1b083ab443b897d6880 I changed `QUDA_DIRECT_SOLVE` into `QUDA_DIRECT_PC_SOLVE` following the discussion in https://github.com/sunpho84/nissa/pull/43 with @kostrzewa and @Marcoga…

It seems that the preparations for ROCm 6 have broken compilation with our current production stack based on ROCm 5.2.3 on LUMI-G (at least for me). Note that 5.2.3 is the default on the machine and t…

When using tmLQCD as an interface to drive QUDA solvers involving both light and ND inversions, the former using MG preconditioning, `invert_doublet_eo_quda` will not initialise its solver parameters …

While testing force offloading I seem to have stumbled upon an issue with double-half CG leading to a substantial increase in the number of iterations between QUDA commit 02391b124 which we have been …

@simone-romiti observed in his run on 6 Juwels Booster nodes on a 48c96 lattice at the physical point (`amu=0.00077`) at `kappa=0.1400080` that the MG diverges rather frequently after being refreshed.…
