Where can I find out more (enough) about Processor in Memory (PIM) Mining (Monero and a few suitable other Cryptocurrencys) on a PCIe Card?

One example of such a Card is the Micron D480 Automata Processor: http://www.micronautomata.com/hardware

PIM (also Processing in Memory) is a Processor tightly coupled to memory, similar to a Processor with a huge Cache.

Quote from this Interview:http://www.techradar.com/news/computing-components/processors/comparing-micron-s-automata-processor-to-gpgpu-fpga-and-classic-co-processors-1238086

"... the Automata Processor is designed to address a class of problems for which neither CPUs or GPGPUs are well suited. For problems that are based on massive parallelism and require the random, comparison based operations often associated with applications in bioinformatics, pattern recognition, data analytics and image processing the Automata Processor is likely a superior solution.".


"Although GPGPUs are certainly more 'parallel' than CPUs, GPGPUs still fall far short of the fine grained parallelism that is found in the Automata Processor. In the AP, tens of thousands of small analysis engines (we call them STEs) are used to create individual thread execution units that are assigned to analyze a data stream.".


"Although the Automata Processor is considered Turing complete, it would likely not be a good choice to use for implementation of large scale Boolean logic circuits. The Automata Processor was designed from the ground up to enable highly parallel comparison and routing operations.".

The D480 does 1536K STEs (per Clk?) and it's FPGA does 270,000 LEs / 101,620 ALMs with 17Mb embedded memory and 4GB DDR3 SDRAM, per board.

Is there a reason PIM, possibly the example above, could not be used for Cryptomining? - I did Search and this Board is years old (with the concept of PIM being much older).

A second example (I discovered after hours more Searching) of using a "Dataflow Engine Technique" is the Maxeler MPC-C series Node: https://www.maxeler.com/products/mpc-cseries/ .

A 1U MPC-C series machine is a server-class HPC system with 12 Intel Xeon CPU cores, up to 192GB of RAM for the CPUs and multiple dataflow compute engines closely coupled to the CPUs. Each node typically provides the compute performance of 20-50 standard x86 servers, while consuming around 500W, dramatically lowering the cost of computing ...".

It has some Software available that is called the Maxeler/HybridMiner: https://libraries.io/github/maxeler/HybridMiner and the Maxeler Bitcoin-miner https://github.com/maxeler/Bitcoin-Miner both which run on the Node and accelerate part of the work (not sure it's much more than an accelerator but these Devices do hundreds of trillions of operations on millions of memory locations - so like a million Core GPU, but it's PIM).

If I had more Reputation I would add the new Tag: memory-mining .

Basically a Developer Board is available from Micron and they have DIMM compatible Modules (if your Computer knew how to use this kind of Memory Stick) that just plug in (see image). Maxeler's is a 1U Rack.

Thanks for your replies and answers.A PIM DIMN

Edit July 24 2017:

I found an Article on Wccftech with a Slide that shows AMD is investigating PIM: http://wccftech.com/xbox-one-may-be-getting-a-new-apu-based-on-amds-polaris-architecture/ .

Slide dated 2014 from an AMD Zen Raven Ridge Article by Khalid Moammer dated Jan 1 2016

It would be speculative to assume that this is going to be a Threadripper styled APU - but that seems what the Article is putting out there (the name Threadripper wasn't known back then).

Update: 26 Mar, 2018:

Teledyne e2v has announced the Qormino® QT1040-4GB, a Quad core QorIQ™ T1040 processor (PowerPC e5500) tightly coupled with 4GB of DDR3L SDRAM.

Expect this trend to continue as more powerful processors become tightly coupled with ever increasing amounts of faster memory.

You'd have to create a mining program specifically targeting the PiM PCIe card (using the manufacturers SDK).
