MP 7,1 MP7,1's kernel_task's Real Memory use ?

Subject: MP7,1's kernel_task's Real Memory use ?

I'm trying to figure out how much User RAM (memory) will I have available on my MP7,1 with its installed 384 GB RAM.

On my MBP13,3 (4-cores) that has 16 GB RAM installed I see at times the kernel_task consumes anywhere from 2 GB to 4 GB. Thus in the worse case I figure I have some 12 GB available for my user applications. This then allows me to use 1.5 GB of RAM for each thread I use in my multi-threaded applications.

I'm curious to know how much RAM the kernel_task on my MP7,1 will consume as that will limit how much RAM I can assign/use per thread.

I will know the answer to this next week when I finally receive my MP7,1.

When you respond to my OP please indicate your installed RAM amount and how much Real Memory your kernel_task is using. The Real Memory value can be observed using the Activity Monitor's Memory tab ("Real Mem" column) in the Utilities folder.

Also, if you have the time please also indicate what the value is for the "Wired memory".

Thanks...

Activity Monitor Memory Tab generally has five columns related to memory usage of a process. Memory, is the generic memory usage of a process. real memory rsize, is the resident memory of a process using now. the resident memory also called active memory. for the kernel_task, the RSIZE for this one is extremely different on different machine according to your HW configuration, mainly the RAM. You can see my MP 7,1 , the kernel_task occupies 18.74GB real memory, this is the kernel data structure, kernel buffer cache, etc.

Wired memory is the memory which must be pinned in the physical memory and those memory cannot be swapped out along with the OS running. These can be Hardware Map, Peripheral DMA etc. These memory can be extremely varied on different machine.
