Hi! Is uMsg really supported on fpga-bdx-opae?

[NLaza3]

I am trying to implement UMsg on fpga-bdx-opae servers on Intel HARP with OPAE sdk. I have been successful in simulating the design with ASE. When I run it on hardware, I get errors.

1. I tried using the API for getting the UMAS pointer: fpgaGetUmsgPtr() but it returns a FPGA_NO_MEMORY error.

2. Output for fpgaGetNumUmsg() gives me that there are 0 UMsgs supported.

Is there something that I might be missing since the document I’m referring to clearly mentions that “UMsg is only supported in the Integrated FPGA Platform”, which “fpga-bdx-opae” satisfies.

Hi,

May I know which processor are you using in your system? The UMsg can only be supported if you are running the Intel PAC card with Intel XEON Processor.

May I know which PAC card are you using?

Hi,

After further checking, the UMsg is only supported in special FPGA device which is teh Intel XEON-FPGA Hybrid device.

You may refer to https://www.anandtech.com/show/12773/intel-shows-xeon-scalable-gold-6138p-with-integrated-fpga-shipping-to-vendors for the announcement of the Xeon Gold 6138P with Arria 10 FPGA.

Hi,

Thank you very much for the answer! However, it is still not clear how we can access a server with such a device to run our experiments on HARP. https://wiki.intel-research.net/FPGA.html states that fpga-bdx-opae cluster is built with integrated XEON-FPGA Hybrid devices you mentioned. However, we observe uMsg is not working on that machine and AVX-512 is not supported either (gcc explicitly tells that).

Is fpga-bdx-opae a right server to work with XEON-FPGA Hybrids? Seems like is has the right FPGA, but the processor differs from the one you mentioned. Can you kindly give us a little more information on how we can access a server that is powered by Xeon Gold 6138P so we can play around with uMsg and AVX-512? I think, this is more vLab/HARP infrastructure specific question though.

Hi,

I am only able to support you on the Intel PAC card. I would recommend you to submit your is https://forums.intel.com/s/group/0F90P00000018wRSAQ/harp
