Determining CPU Speed in AIX

Question Determining CPU Speed in AIX

Answer

This document applies to AIX Versions 4 and 5. While there is not a direct command to determine processor speed in AIX V4, the best place to start is with the uname command. Executing uname -m produces output of the following form: xxyyyyyymmss The meanings of the placeholders are as follows: xx = 00 yyyyyy = Unique CPU ID mm = Model ID <- these are the numbers to use to determine CPU speed ss = 00 (Submodel) By cross-referencing the values from the uname -m output with the table below, you can easily determine the processor speed. To determine cpu speed with AIX V5 (which includes power5 systems and above), use the following commands: lsattr -El proc0 prtconf pmcyles -m The frequency line returns the speed of the cpu. Note on some machines the value represented by the frequency line will have to be rounded to the nearest integer. For example, the frequency reported on a 7025-F80 is 451200000, which is then rounded to 450MHz.

However, in some cases the information gained from the uname -M command can be helpful. uname -M Machine Type Processor Speed Processor Architecture IBM,7017-S70 7017-S70 125 RS64 IBM,7017-S7A 7017-S7A 262 RD64-II IBM,7017-S80 7017-S80 450 RS-III IBM,7017-S85 pSeries 680 600 RS64-IV IBM,7025-F40 7025-F40 166/233 PowerPC 604e IBM,7025-F50 7025-F50 See Note 4 PowerPC 604e IBM,7025-F80 7025-F80 See Note 5 RS64-III IBM,7025-6F0 pSeries 620 See Note 7 See Note 7 IBM,7025-6F1 pSeries 620 See Note 7 See Note 7 IBM,7026-H10 7025-H10 166/233 PowerPC 604e IBM,7026-H50 7025-H50 See Note 4 PowerPC 604e IBM,7026-H80 7025-H80 See Note 5 RS64-III IBM,7026-M80 7026-M80 500 RS64-III IBM,7026-B80 pSeries 640 See Note 9 Power3-II IBM,7026-H10 7026-H10 166/233 PowerPC IBM,7026-H50 7026-H50 See Note 4 PowerPC IBM,7026-H70 7026-H70 340 RS64-II IBM,7026-H80 7026-H80 450 PowerPC IBM,7026-M80 7026-M80 500 PowerPC IBM,7026-6H0 pSeries 660 450MHz RS64 III IBM,7026-6H0 pSeries 660 600MHz RS64 IV IBM,7026-6H1 pSeries 660 See Note 7 See Note 7 IBM,7026-6M1 pSeries 660 See Note 8 See Note 8 IBM,7028-6C1 pSeries 610 See Note 9 POWER3 II IBM,7028-6E1 pSeries 610 See Note 9 POWER3 II IBM,7040-681 pSeries 690 1.1 or 1.3GHz POWER4 IBM,Model 7042/7043 (ED) 7043-140 166/200/233/332 PowerPC IBM,Model 7042/7043 (ED) 7043-150 375 PowerPC IBM,Model 7042/7043 (ED) 7043-240 166/233 PowerPC IBM,7043-260 7043-260 200 Power3 IBM,7044-170 7044-170 See Note 6 POWER3 II IBM,7044-270 7044-270 375/450 POWER3 II IBM,7046-B50 7046-B50 375 PowerPC 604e IBM,7248 7248-100 100 PowerPersonal IBM,7248 7248-120 120 PowerPersonal IBM,7248 7248-132 132 PowerPersonal J-Series, R-Series, and G-Series systems: You can determine the processor speed in an MCA SMP system from the FRU number of the CPU card by using the following command: lscfg -vl cpucard0 | grep FRU This will produce the following output: FRU Number..................C1D FRU Number Processor Type Processor Speed E1D PowerPC 601 75 C1D PowerPC 601 75 C4D PowerPC 604 112 E4D PowerPC 604 112 X4D PowerPC 604e 200 E-Series and F-30 systems: For the E-series and F-30 systems, use the following process to determine CPU speed. Execute: lscfg -vp | more Look for the following stanza: procF0 CPU Card Part Number.................093H5280 EC Level....................00E76527 Serial Number...............17700008 FRU Number..................093H2431 Displayable Message.........CPU Card Device Specific.(PL)........

F-50 and H-50 systems and SP Silver Node: The following commands can be used to determine the processor speed of an F-50 system. Execute: lscfg -vp | more Look for the following stanza: Orca M5 CPU: Part Number.................08L1010 EC Level....................E78405 Serial Number...............L209034579 FRU Number..................93H8945 Manufacture ID..............IBM980 Version.....................RS6K Displayable Message.........OrcaM5 CPU DD1.3 Product Specific.(ZC).......PS=0013c9eb00,PB=0009e4f580,SB=0004f27 ac0,NP=02,PF=461,PV=05,KV=01,CL=1 In the line containing Product Specific.(ZC), the entry PS= (boldface here), is the processor speed in hexadecimal notation. To convert this to an actual speed, use the following conversions:  0009E4F580 = 166 MHz 0013C9EB00 = 332 MHz The valuePF= indicates the processor configuration.  251 = 1 way 166 MHz 261 = 2 way 166 MHz 451 = 1 way 332 MHz 461 = 2 way 332 MHz Each 2 way processor resides on one CPU card. 4 way systems will display two entries for the Orca M5 CPU card. Only 6-way (F-80) systems run at 500 MHz, all others run at 450 MHz. Use the L2cache size to determine the speed of the cpu: lsattr -El L2cache0 L2cache size CPU speed 1mb 333MHz 4mb 400MHz 8mb 450MHz It can be configured with 1-, 2-, 4-, or 6-way, RS64 III or RS64 IV, 64-bit processors. Systems configured with the maximum of six processors run at 668 MHz, while other configurations run at 600 MHz (RS64 IV) or 450MHz (RS64 III). To determine the number of processors on the system run lsdev -Cc processor and to determine the type of processor run lsattr -El proc0. The system 7026 Model 6M1 (p660) has two processor slots to accommodate two 2-way or 4-way processor cards to create a system with 2, 4, 6, or 8 processors. Each processor slot can hold one of the following processor cards: 2-way 750 MHz RS64 IV with 8 MB L2 cache per processor 4-way 750 MHz RS64 IV with 8 MB L2 cache per processor 2-way 500 MHz RS64 III with 4 MB L2 cache per processor To determine the number of processors on the system run lsdev -Cc processor and to determine the type of processor run lsattr -El proc0. For pSeries servers that use a 350 MHz or 450 MHz processor, run the following command lscfg -vp | more  Then look for the Processor Card entry. The PF field, in the Product Specific (ZC) line, indicates the processor type as follows: PF Value Card type FRU p/n 754 375 MHz one way card w/ 4 MB L2 cache 09P0399 764 375 MHz Two way card w/ 4 MB L2 cache 09P0406 768 375 MHz Two way card w/ 8 MB L2 cache 09P0143 7A8 450 MHz Two way card w/ 8 MB L2 cache 09P4478
