Methods and apparatus to optimize dynamic memory assignments in multi-tiered memory systems

An apparatus to perform dynamic memory assignments in multi-tiered memory systems, the apparatus comprising:

• a malloc information processor to, during an offline profiling run of a computer application, perform a first backtrace responsive to a first malloc function call to identify a first path preceding the first malloc function call and identify a size of a buffer in memory allocated to the first path;
• a temperature determiner to determine an indicator corresponding to a temperature of the buffer allocated to the first path;
• a path determiner to, during runtime, perform a second backtrace responsive to a second malloc function call to identify a second path preceding the second malloc function call;
• and
• a memory tier allocator to, responsive to the second path corresponding to the first path, allocate memory from a tier of memory based on the indicator.

A method to perform dynamic memory assignments in multi-tiered memory systems, the method comprising:

• during an offline profiling run of a computer application:
• responsive to a first malloc call function, performing a first backtrace to identify a first path preceding the first malloc function call and identify a size of a buffer in memory allocated to the first path;
• and
• determining an indicator corresponding to a temperature of the buffer allocated to the first path;
• and
• during runtime:
• responsive to a second malloc function call, performing a second backtrace to identify a second path preceding the second malloc function call;
• and
• responsive to the second path corresponding to the first path, allocating memory from a tier of memory based on the indicator.
