New CMIPS v.1.0.5

Leave a reply

We are proud to release a new version of CMIPS.

cmip-v-1-0-5-start-thread

This new release improves:

  • Number of threads updated to 200

As most powerful Commodity Servers are approaching to 100 cores we doubled the number of concurrent threads for the tests. Any Server bellow 200 cores can be tested.

The CMIPS score scale compatibility  is maintained, so values are consistent with older CMIPS versions, but times for the tests are doubled.

  • Info on max threads on the system is printed and written to cmips.log (/proc/sys/kernel/threads-max)
  • Info on CPU is printed and written to cmips.log (/proc/cpuinfo)
  • The output in the screen is also nicer
  • An explicit use of variable has been made just to avoid compiler optimizations in some C++ compilers (when the variables are not used)
  • Thread variables are isolated to the Thread scope
  • Improved code fore readability
  • Threads use local variables l_ prefix from MT Notation to clarify
  • Source code project updated to NetBeans 8.

The new information provided at the start of the cmips binary (also written to the log) includes the number of max-threads configured in the system and the CPU info found on /proc/cpuinfo.
