Hi, In a previous email i was working on a benchmark, for examining performance changes between ITK3 and 4. I thought it would be handy to print the system info in the benchmark result, to keep track. So, i used itksys::SystemInformation. However, the results seem... questionable. its worth noting they seem the same between ITK 3 and 4.
The code that generated this is here https://github.com/rupertbrooks/itkbench Its worth noting that itksys::SystemInformation doesnt seem to be documented, so perhaps im just breaking all the rules here. Should i JIRA this? On a Windows system - *** indicates a questionable result $ relwithdebinfo/itkbench System: CAMD5C5PMN1 *****Processor: Pentium III (0.18 micron) With 1 Or 2 MB On-Die L2 Cache Serial #: ***** Cache: -1 Clock: 2800 ***** Cores: 4 cpus x 1 Cores = 4 OSName: Windows Release: XP Professional Version: Service Pack 3 (Build 2600) Platform: x86 Operating System is 32 bit ITK Version: 4.3.0 Virtual Memory: Total: 2047 Available: 2008 Physical Memory: Total:3581 Available: 1655 My employer is not so cheap that we are still using P3s :-) CPUID reports it as a Intel Xeon W3530 Bloomfield. Core i7 would be a fine identification as well. Also, theres not 4 chips with 1 core each, but 1 chip, with 4 cores. This might be me misinterpreting the meaning of physical vs logical, but see below. On a Ubuntu system ./itkbench System: morrigan ***Processor: Intel(R) Core(TM)2 Duo CPU T9500 @ 2.60GHz Serial #: Cache: 2048 Clock: 2003 **** Cores: 4 cpus x 4 Cores = 16 OSName: Linux Release: 3.0.0-21-generic Version: #35-Ubuntu SMP Fri May 25 17:57:41 UTC 2012 Platform: x86_64 Operating System is 64 bit ITK Version: 4.3.0 Virtual Memory: Total: 20795 Available: 20795 Physical Memory: Total:8001 Available: 3361 Here its only the # of cores that are questionable. Theres one physical chip, with 4 Core2 architecture cores on it. So strictly speaking, its a Core2 Quad. /proc/cpuinfo gets it as model name : Intel(R) Core(TM)2 Quad CPU Q8200 @ 2.33GHz Best, Rupert -------------------------------------------------------------- Rupert Brooks [email protected]
