Hi All,
My question may not be exactly related to linux.
We know that a 32 bit processor can access a max of 4GB of RAM, but two processor systems with 8GB Ram are quite common these days.
My questions are :
1. Are both processors able to access a full 8GB of RAM?
1.1 if yes then how. ?
1.2 if not, then is each of the 4GB of RAM on these systems local to respective processor ?
1.2.1 In such a case how would a process running on processor A access memory or communicate with another process running on processor B.
2. How is linux kernel able to handle 8GB or more of RAM, when the maximum address the Compiler / CPU can generate is 4GB -1.
Any pointers in this regards ?
Regards
Kapil Sethi
