I'm working on Linux, my architecture is a Intel(R) Xeon(R) CPU X3430 @ 2.40GHz. It has 4 cores within the processor.
How can I know how many chips are there within the processor? I have searched in the cpuinfo file, but I only find information about of number of cores within the processor and the number of proccesors in the system, but I can't find the number of chips within the processor.
Can anyone help me? How can I know if my processor is multi-chip or single-chip?
P.S. I have revised the Intel technical specification but I didn find anything.
Thanks and regards,
This processor has 1 physical processor and 4 cores.
You need to contact Linux* developers and ask them what do they mean by Multi-chip?
Are they referring to number of cores, or number of physical processors?
From our side, if the processor has 4 cores, I would say it is Multi-ship, but you need to ask Linux* if that is what they call Multi-chip?
They are not refering to number of cores, or number of physical processors. They are refering to number of chips within a physical processor; i.e. I am attaching a image with 8 cores (Intel Xeon 5345 architecture). This architecture has 2 physical processors, each physical processor has 2 chips, then this architecture is multi-chip because the processor 0 has 2 chips (multi-chip) and another processor has other 2 chips (multi-chip, too). Also, each chip has 2 cores.
I need to know the exact structure of the processor (if it is multi-chip or single-chip) because I need to know exactly how many cores share L1, L2 and L3 cache and what cores exactly are they?
Perhaps the data sheet can give you the information your looking for? http://www.intel.com/products/server/processor/xeonE3/index.htm http://www.intel.com/products/server/processor/xeonE3/index.htm
The architecture of a QPI processor is completely different than the FSB processor shown in the picture.
Thanks for theirs answers,
In the data sheet document is all information that I am looking for in the part of 1) Introduction and 1.1) Processor Feature Details.
This architecture has only one chip inside of the processor (It's a single-chip), also it contains the following characteristics:
- Four cores.
- A 32-KB insrtuction and 32-KB data first-level cache (L1) for each core.
- A 256-KB shared instruction/data second-level cache (L2) for each core.
- 8-MB shared instruction/data last-level cache (L3), shared among all cores.
Regards and thanks for all.
