FDS6576 Article About

Last year, Intel showed a prototype 80-core chip. Although the semiconductor industry, this achievement in letters, but the real problem out soon: Intel x86 kernel will make these ultra-use multi-core processors? These processors can run existing software and operating system? How do you solve the data communication, fever and other potential problems? IBM introduced a receive data to quickly analyze the data of high-performance computer systems, can improve the security monitoring, decision-making areas such as the Wall Street trading speed and accuracy. IBM Technical Manager at the time attended by a Wall Street showed the meeting, called SystemS system. Analysts said the news is a new stream computing an important step in the commercialization.
Where most of the time spent, is the kernel or user process? By vmstat, mpstat, sar, ps, prstat can answer this question. All have similar types of resources are equally busy? The significance of this problem is to find the unequal distribution of resources. For example, a disk may be the bottleneck, CPU or a CPU is more busy than others. On the CPU, see mpstat. On the disk, with iostat. Which or what processes are using the most resources? These commands can be seen with the use of CPU and memory up to the process: ps-eo pid, pcpu, args | sort +1 n ps-eo pid, vsz, args | sort +1 n / usr / ucb / ps aux | more output to be sorted, using the most CPU and memory process at the top. Solaris 8 operating environment provides prstat, it gives the CPU and memory usage of a dynamic annotation. the output of prstat-cvm very useful.
