Intel® MPI Library Reference Manual for Linux* OS
The cpuinfo utility provides processor architecture information.
cpuinfo [[-]<options>]]
<options> |
Sequence of one-letter options. Each option controls a specific part of the output data |
g |
General information about single cluster node shows:
|
i |
Logical processors identification table identifies threads, cores, and packages of each logical processor accordingly.
|
d |
Node decomposition table shows the node contents. Each entry contains the information on packages, cores, and logical processors.
|
c |
Cache sharing by logical processors shows information of sizes and processors groups, which share particular cache level.
|
s |
Microprocessor signature hexadecimal fields (Intel platform notation) show signature values:
|
f |
Microprocessor feature flags indicate what features the microprocessor supports. The Intel platform notation is used. |
A |
Equivalent to gidcsf |
gidc |
Default sequence |
? |
Utility usage info |
The cpuinfo utility prints out the processor architecture information that can be used to define suitable process pinning settings. The output consists of a number of tables. Each table corresponds to one of the single options listed in the arguments table.
The architecture information is available on systems based on the Intel® 64 architectures.
The cpuinfo utility is available for both Intel microprocessors and non-Intel microprocessors, but it may provide only partial information about non-Intel microprocessors.
