One embodiment of the present invention sets forth a technique for dynamically allocating memory using one or more lock-free FIFOs. One or more lock-free FIFOs are populated with FIFO nodes, where each FIFO node represents a memory allocation of a predetermined size. Each particular lock-free ...
in computer memory management, fifo is used to manage the allocation and deallocation of memory blocks. when a program requests memory, blocks are allocated in the order they are requested. similarly, when memory needs to be freed, the blocks are deallocated in the order they were allocated, f...

After increasing that I am able to scale more connections. For fifo allocation, I see that we can use either shm or memfd. Is there any recommendation/preference on which one to use? Does memfd also internally use /dev/shm for memory allocation? Regards, Akshaya N On Fri, Oct 25, 2019...

However, you might want to explicitly control their placement in memory, as shown in the following example. This constraint is useful to preserve the placement of FIFO resources between runs of the AI Engine compiler. Note the following considerations for FIFO constraints. If FIFO constraints are ...

Allocation for each Get request confuses me because with high probability GC will spend much more time (and in fact a lot of memory will be spent on it too) to clean up these allocations than we will gain. And there are several ways of solution here use atomic.Value and put up with ...
