Cache Latency Computation Download [Updated] This is a command line application that can gather information about the cache hierarchy of your system. For each cache level, it provides its size and its latency. I have used an old version of this program on another system (3.11.0) and everything went fine. This time I'm having a problem when I run this program (3.11.3). The problem is that I can't get information about the cache levels that have at least one cache with a line size of 32 or 64. If I do it on the other system, I can get this information. I can't figure out why I can't get this information. If I can't get any information about a particular cache level, the program shows only the information about the fastest cache level. Is there anything wrong with my code or is there any other reason that I can't get any information about the size and latency of a cache with a line size of 32 or 64? The program source code is available in my GitHub repository. I hope someone can help me. Thank you very much. A: the problem is that I can't get information about the cache levels that have at least one cache with a line size of 32 or 64 On my 3.11.3 machine, the following two caches are present: 5431: size: 6144B, cache line size: 32B, latency: 24ns 5392: size: 6144B, cache line size: 64B, latency: 25ns What I can tell from the output you posted is that there is no cache at all (line size: 32 or 64) in those two lines. So I don't see how the program could have possibly failed there. The outputs are consistent with what I expect from a non-disabled cache (except for cache types as I don't have that information). If you're looking for a specific cache line size, use a constant line size of 64 bytes. Edit: Here is my output on 2.6.28-21-generic (a kernel with a disabled cache (cache=0)): cache:size:006280:0 size:0B Cache Latency Computation =============================== Cache Latency Computation is a simple command line application that provides a unified interface to access the cache hierarchy of your system. It gathers informations about the cache hierarchy for each level (of associativity, size and latency). It can be used to gather information about your system's cache hierarchy: * Each cache level is reported with its size and its latency. * Cache size is calculated thanks to the "util" command. * Cache size is also based on the "Num_Traces" provided as input. * Cache size is not necessarily equal to the number of cache lines. * Cache latency is calculated thanks to the "util" command. * Cache latency is also based on the "Num_Traces" provided as input. * You can enter a number of trace probes. This number is only used for cache latency computation. * Cache size is computed on the top level cache. * Cache latency is computed on the top level cache. Cache size computation is based on the definition of the "util" command. Examples: First, a simple way to measure cache size and cache latency of the top level cache: .. code:: sh # Verbose output $ cd /home/mickael/cachestat $./cachestat -h .. Number of probe points = 5 Cache size = 1.55 MB Cache size (about 45% of the top level cache size) Cache latency = 8 us Cache latency (about 75% of the top level cache latency) The utility "util" (``util -c 100``) provides another way to compute cache size and cache latency: .. code:: sh # Verbose output $ cd /home/mickael/cachestat $./cachestat -l -c 100 ..
