CheriABI: enforcing valid pointer provenance and minimizing pointer privilege in the POSIX C run-time environment Davis et al., And this all has to work for whole-system executions, not just the C-language portion of user processes. Most programs (almost 800 C programs in the FreeBSD source tree) require no modifications.

HammerDB is a software application for database benchmarking. Databases are highly sophisticated software, and to design and run a fair benchmark workload is a complex undertaking. The Transaction Processing Performance Council (TPC) was founded to bring standards to database benchmarking, and the history of the TPC can be found here.

These, let’s call them metal languages , include FORTRAN (introduced in 1957), C (1972), and C++ (1985). Programmers continue to write applications in them, and they continue to evolve: the just approved C++20 standard is the latest example. Despite their age, these languages are far from dead!

Depending on the application programming language, which is specified as an argument in the command line, the tool launches a compatible image profiler that contains everything it needs to successfully produce the flame graph. In secure environments where policies are defined, launching such a pod should be done by a trusted privileged user.

These techniques work well for scientific programs that are dominated by arrays. However, they are ineffective on object-based programs because objects do not fall neatly into fixed-size blocks and have a more irregular layout. Consider a B-Tree node from the B-tree Java benchmark: Uncompressed, it’s memory layout looks like (a) below.

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.

Programming Languages. When you download the source code for HammerDB you can see that the programming language it is written in is called TCL. TCL was designed as a language to be closely tied with C/C++ and at this lower level there is the compiled TCL (tclsh) or TCL/TK (wish) interpreter and supporting libraries.

When you own all of the code then this may involve some back of the envelope estimates, competitive benchmarking, or intuition tuned by experience. It shouldn’t take much C# code to make an app that monitors the root of all drives, using buffer sizes that start small and gradually get larger. You know where to find me.

Customer retention programs can require the identification of customers who are likely to stop the relationship with a retailer but can change their minds under the influence of incentives. This metric reveals customers with high revenue potential, hence it can be used in loyalty programs and usage expansion campaigns. Kadie, 1998.
