drives. SAS 8408E, which optimizes raid performance with high-performance Intel I/O processors and increases bandwidth through the Pci-express host interface, provides an intelligent and robust raid solution. In addition, this adapter supports 256MB DDRII SDRAM for data caching and supports the smart Portable battery backup module (ITBBU), which saves cached data under a 72-hour full power outage. The portable caching module can even be moved to a new MegaRAID adapter, while preserving the full

This problem comes from example 1-2. The ship can be loaded in a step-by-step, with one container per step, and which container to consider. According to this idea, the following greedy guidelines can be used: from the remaining crates, select the smallest weight of the box. This order of choice ensures that the total weight of the selected containers is minimal, allowing for more containers to be loaded. Based on this greedy strategy, the lightest container is selected first, then the lighter o

Dynamic tracking Technology (iv): implementation of GO program dynamic tracking based on Linux BCC/BPF

standard symbol table for function lookups. In this case, I use LIBGO as a measurement tool (assuming "Lib" before "go:") as a binary dynamic link library issued by GCCGO (Libgo contains a FMT package). Uprobes can connect to a process that is already running or, as I do now, as a binary repository, capturing all calls to its own process. To improve efficiency, I make a count of function calls in the kernel context, sending only the count to the user space. For example: $ file hellohello:elf 64
