Bottom line: Big accelerator Memory (BaM) is a newly developed structure from Nvidia, made in collaboration with IBM and a number of other US universities. The expertise goals to enhance information heart efficiency by giving GPU-accelerated functions direct entry to giant quantities of SSD storage, bypassing the necessity for a general-purpose CPU.
The analysis crew behind BaM notes the elevated use of GPUs inside fashionable information facilities for his or her excessive reminiscence bandwidth and compute capabilities. However, they argue that the normal mannequin of executing functions and workloads has concerned a CPU-centric method, which might result in extreme overhead and I/O bottlenecks between elements.
With BaM, GPU-accelerated functions similar to analytics and AI workloads like machine studying and neural networks coaching might see a major efficiency profit when it comes to information transfers by taking the CPU out of the equation and enabling the GPU to immediately learn and write small quantities of information to NVMe SSDs on-demand.
As The Register stories, the BaM structure is made up of two important components. The first is a software-managed cache of GPU reminiscence and the second is a software program library for the GPU that lets it immediately discuss to NVMe storage and request information by using a customized Linux kernel driver, RDMA and PCIe interfaces.
The researchers additionally demonstrated BaM’s viability with a prototype powered by Linux and off-the-shelf GPUs and NVMe SSDs. Some of the benefits seen at this level embody higher synchronization and environment friendly use of I/O bandwidth, alongside parallelized storage entry.
Although focused at enterprise/companies, the BaM API might additionally profit consumer-grade SSDs, in accordance with the researchers, delivering aggressive efficiency towards way more costly DRAM-only options. While the underlying expertise and use instances are totally different, BaM looks like an analogous GPU/SSD implementation as Microsoft’s not too long ago launched DirectStorage for PCs.
