ROCm Is AMD’s No. 1 Precedence, Exec Says

SANTA CLARA, CALIF. — “If you consider the product portfolio that AMD has, it’s arguably the broadest within the business by way of AI compute,” Vamsi Boppana, senior VP of the AI group at AMD, stated in his keynote handle on the latest AI {Hardware} Summit. AMD’s {hardware} portfolio consists of data-center–class CPUs and GPUs, shopper GPUs, FPGAs and the Ryzen 7040, a consumer CPU with NPU designed for PCs. Software program is essential to unlocking the efficiency of those totally different {hardware} platforms. However how does AMD compete with its GPU opponents’ robust choices, given its extra various {hardware}?
AMD’s software program stacks for every class of product are separate: ROCm (quick for Radeon Open Compute platform) targets its Intuition information heart GPU traces (and, quickly, its Radeon shopper GPUs), Vitis AI targets its FPGAs, and ZenDNN targets its consumer units.
How far alongside is AMD with unifying these stacks?
“We now have huge buyer pull coming, and that’s dictating fairly a little bit of our near-term plans,” Boppana instructed EE Instances in an interview after his speak right here. “The aircraft is flying proper now, so we can’t disassemble the engine. Nonetheless, we’re completely doing issues on the foundational stage to make extra unification occur in our stack.”
Boppana stated that there’s some frequent infrastructure and tooling underlying all three stacks, together with an ongoing effort to make a standard quantizer.
“Over time, we need to get to a spot the place customers have one execution supplier, and beneath that, it is possible for you to to pick out [a hardware target],” he stated. “Within the close to time period, modules are shared throughout stacks, and over time, as issues like heterogeneous platforms are going to turn into prevalent, the unified components begin coming via.”
A unified stack can be useful for heterogeneous methods, Boppana stated, particularly the place partitioning is required. At present, the Vitis stack handles CPU plus xDNA targets, however he agrees that each automated and user-driven partitioning will likely be needed.
“In that state of affairs, we want to have the ability to take an issue assertion and reduce the graph, such that each components of the graph get executed on [different parts of the hardware], and they should inter-operate,” he stated.
‘ROCm has developed’
ROCm is much less mature than opponents’ GPU software program choices, with Nvidia’s mature CUDA stack typically seen as a giant a part of the market chief’s aggressive benefit.
“Software program is a journey,” Boppana stated. “Anyone who has written or managed complicated items of software program is aware of it takes time. The excellent news is, we now have been on the journey…ROCm has developed.”
AMD has made ROCm the No. 1 precedence on the firm stage within the final yr, Boppana stated, standing up a brand new group that’s introduced collectively property from all the corporate’s software program contributions.
“We now have a lot bigger assets really engaged on software program, and [AMD CEO Lisa Su] has been very clear that she desires to see important and continued investments on the software program facet,” Boppana stated. “We now have agreed to offer individuals internally, we now have acquired Mipsology, and we want to develop expertise each organically and inorganically.”
AMD additionally just lately stood up an inner AI models group to extend its expertise utilizing its personal software program stack.
“We would like a a lot tighter suggestions loop,” Boppana stated.
Utilizing open supply to problem Nvidia
AMD has embraced OpenAI’s Triton, an open-source programming language and compiler for GPUs that guarantees to supply an open-source different to Nvidia’s CUDA for builders who need to write high-level code that performs optimally on the {hardware}.
“There are totally different personas which might be programming [our GPUs],” he stated. “[Triton] is a stage of abstraction that individuals are comfy with. It’s productive. And it will get to {hardware} in a fairly environment friendly, cogent style. However for different clients, that doesn’t matter; they don’t have to develop new kernels. For them, we are able to ship libraries. So, it’s only a matter of who desires to make use of us.”
In distinction to Nvidia’s method with CUDA, which is generally proprietary, most of AMD’s ROCm stack is open supply.
“We associate with the [AI frameworks] and the individuals writing the libraries and say, ‘You probably have a kernel you need to put collectively, you may take one thing that exists from us, however in case you discover there’s the chance so that you can optimize supply code, [you can]’,” he stated. “Then we now have so many extra individuals which might be keen and capable of contribute. So, that’s crucial and really highly effective for us: We expect it’s the appropriate strategic course for us to take.”
MI300 samples are presently with clients, Boppana stated, and each clients and AMD have AI coaching workloads up and working, with availability coming on the finish of this yr.
ROCm will likely be essential to the success of each the MI300 and MI300X.
“Being candid, we now have just a few locations to develop,” he stated. “Permitting the group to contribute [to ROCm] alongside us helps us bridge the hole quicker.”
