Introduktion
Coreinfo är ett kommandoradsverktyg som visar mappningen mellan logiska processorer och den fysiska processorn, NUMA-noden och socketen som de finns på, samt cachen som tilldelats varje logisk processor. Den använder funktionen GetLogicalProcessorInformation i Windows för att hämta den här informationen och skriver ut den på skärmen, vilket representerar en mappning till en logisk processor med en asterisk, t.ex. "*". Coreinfo är användbart för att få insikt i systemets processor- och cachetopologi.
Installation
Extrahera arkivet till en katalog och kör sedan Coreinfo genom att skriva från katalogen Coreinfo i konsolen på en 32-bitars Windows-version eller Coreinfo64 för en 64-bitarsversion.
Använda CoreInfo
För varje resurs visas en karta över os-synliga processorer som motsvarar de angivna resurserna, med *som representerar tillämpliga processorer. Till exempel i ett 4-kärnsystem, en rad i cacheutdata med en karta över delade kärnor 3 och 4.
Användning: coreinfo [-c][-f][-g][-l][-n][-s][-m][-v]
| Parameter | Beskrivning |
|---|---|
| -C | Dumpa information om kärnor. |
| -F | Dump core-funktionsinformation. |
| -G | Dumpa information om grupper. |
| -L | Dumpa information om cacheminnen. |
| -N | Dumpa information på NUMA-noder. |
| -S | Dumpa information om socketar. |
| -M | Dumpa NUMA-åtkomstkostnad. |
| -V | Dumpa endast virtualiseringsrelaterade funktioner, inklusive stöd för adressöversättning på andra nivån. |
| (kräver administrativa rättigheter för Intel-system). |
Alla alternativ utom -v är markerade som standard.
