Abstract
In one example implementation, a method for generating persistent pointers using non-volatile random access memory (NVRAM) compiler directives in a program for NVRAM based computing systems includes generating a program including modified variables. The modified variables include NVRAM compiler directives indicative of persistent pointer type. The method further includes generating assembly code, including persistent pointer enablers, using the program including the modified variables by a compiler. Furthermore, the method includes mapping information of each NVRAM segment formed by the program with an associated physical address in NVRAM by an NVRAM driver residing in the NVRAM or main memory, maintaining an NVRAM registry including the mapped information by the NVRAM driver, determining valid virtual addresses of processes during runtime using the generated assembly code including the persistent pointer enablers and the NVRAM registry including the mapped information, and generating the persistent pointers from the valid virtual addresses during runtime.
