There are several ways to check the number of CPU. Options are as follows:
1. Using Command tosgetpma we can check the number of CPU in the system. Also, we can check how many CPU are enable to use because based on the license agreement sometimes you might use less CPU than the system have.
# tosgetpma
System:
Name: XXXXXX
Processor:
Type: Xeon (code 7)
CPUs: 72
TD-Enabled CPUs: 72
Max CPUs: 72

2. We can also check the number of CPU by using “machinetype” command
# machinetype
Model: 7011 (S2600WFT)
Productid: Platform=Rx2yzWFT Series=Rx2yzWFT Type=MPP-SM3G NodeVendor=INTEL
Class: Unknown
Node: TPA
Memory: 512GB
BIOS: SE5C620.86B.02.01.5010.C0T07.031920200357
SCSI: Intel RMS3CC080, NETAPP INF-01-00
Drivers: teradata-multipath intel-megaraid_sas mpt2sas
OS: Teradata SLES11 SP3 3.0.101-0.230.TDC.1.R.0-default
Processor In Socket 0: Intel(R) Xeon(R) Gold 6140 CPU @ 2.30GHz
Core 0 Thread 0 : Linux Logical CPU 0
Core 0 Thread 1 : Linux Logical CPU 36
Core 1 Thread 0 : Linux Logical CPU 1
……………………………………………………………….
……………………………………………………………….
Core 26 Thread 1 : Linux Logical CPU 70
Core 27 Thread 0 : Linux Logical CPU 35
Core 27 Thread 1 : Linux Logical CPU 71
3. Number of CPU also can be check using “diagnostic help profile session” command after login to a session.
diagnostic help profile session;
*** Help information returned. 1293 rows.
*** Total elapsed time was 3 seconds.
Cost Profile Parameters
---------------------------------------------------------------------------
SESSION: TD15 [Id = 40, Type = 2] TLE is not enabled

NumCpusPerNode = 7.200e+01
……………………………………………………………………

Results can be used to identify each TCore Level. TCore 1 in this example.
7.200e+01 = 72 CPUS which is equivalent to TCore 1.
5.600e+01 = 56 CPUS which is equivalent to TCore 2.
4.000e+01 = 40 CPUS which is equivalent to TCore 3.
Following way we can also check the TCore level:
# tcore-activation -c
Current TCore Level: 1
