The work includes changes to the CHERI ISA, the C compiler, the C language runtime, the virtual memory APIs, and the CheriBSD kernel. On a context switch the kernel saves and restores user-thread register capability state, and updates virtual-physical mappings. For a macro-benchmark PostgreSQL’s initdb tool was used.

Another big jump, but now it was my job to run benchmarks in the lab, and write white papers that explained the new products to the world, as they were launched. I was mostly coding in C, tuning FORTRAN, and when I needed to do a lot of data analysis of benchmark results used the S-PLUS statistics language, that is the predecessor to R.

Earlier this month I spent a week at the OpenStack conference. But once you realize that there are, in fact, several OpenStack conferences happening at the same time and place, it makes more sense. We also virtualize really well, for those OpenStack users who are focusing on managing armies of developers and swarms of MIS systems.

Virtual consensus in Delos , Balakrishnan et al. USENIX is a nonprofit organisation committed to making content and research freely available – both conference proceedings and the recorded presentations of their events. Without in-person conferences this year, income is down and events are under threat.

CLI tools The Cassandra systems were EC2 virtual machine (Xen) instances. Note that Ubuntu also has a frame to show entry into vDSO (virtual dynamic shared object). I happened to be speaking at a technical confering while still debugging this, and mentioned what I was working on to a processor engineer. include <sys/time.h>
