on modeling infection

Compartmental models are often used to simplify the mathematical modeling of infectious disease. The population is split into compartments and it is assumed each individual in a compartment has the same characteristics. While this may appear to be rather crude, such models have shown to accurately model previous infectious outbreaks[1]....

light-weight way to capture results from cloud HPC/HTC

For large HTC (or HPC) computations on the cloud, ‘spot instances’ (AWS-speak), ‘low-priority VM’ (Azure-speak) or ‘preemptible VM instances’ (GoogleCloud-speak) are the low cost options for compute. Of course, the challenge here is that these instances/VM can vanish at anytime. If you’re doing a large HTC task, you want to make sure you save your result (and/or checkpoint) files as soon as they are generated to persistent storage. Otherwise you lost the computation you just paid for....
