Mention the importance of using the default SSH key location

3

In episode 7, we state: "We want to use the default file, so just press Enter." At a recent Carpentries UK community call, one instructor mentioned that they derailed a...

Should we show an automatically resolvable merge conflict first?

3

Currently in [Conflicts](http://swcarpentry.github.io/git-novice/09-conflict/index.html) the learner encounters GitHub rejecting their push for the first time, and then on pulling encounters a merge conflict that must be resolved manually. This conflates two...

As discussed in #727, this PR changes the text used when creating and resolving a merge conflict, so that it is clearer to the learner how a conflict may occur...

Should text in "conflicts" examples be representative rather than self-describing

1

Up until the episode on [conflicts](http://swcarpentry.github.io/git-novice/09-conflict/index.html), all examples are representative of how git might be used in a real workflow, with Dracula making notes vaguely related to the hypothetical scenario...

Do not compute n_effective when limit is infinite

15

Currently the maximum number of effective samples `n_effective` in `Sampler.sample()` defaults to `np.inf`, implying no limit, yet `self.n_effective` is still computed (and then compared with `np.inf`), which takes time. The...

use accelerator for setCheckerboard in RHMC

2

This goes some way towards #378. One-flavour RHMC is 10–20% faster with this, and gives identical results (i.e. generated configurations, excluding the header, are bitwise identical). Things that could potentially...

HMC on A100 spends large amounts of time in memory copy

3

Since benchmarks show we can get 1.7TFLOP/s for the Wilson kernel on one A100 but only about 230GFLOP/s on an AMD Rome node, it would seem reasonable to expect that...

Very low acceptance for SU(2) 1 adjoint flavour RHMC

2

I'm seeing very low acceptance rates when running the RHMC for SU(2) with one adjoint flavour when compared to what I believe are exactly the same run parameters for HiRep....

External Markdown slides cannot be uncounted

3

When using slides in external Markdown files, adding `data-visibility="uncounted"` doesn't exclude the external slides from the slide count or progress bar. (Using `data-visibility="hidden"` does correctly hide the external slides.) Is...

In trying to understand aportelli/Hadrons#94, it transpires that certain arithmetic operations in Grid will not compile for SU(4). For example, the following test program gives two build errors, one caused...
