xblas_gemv implementation about gemx HOT 2 OPEN

Hi Ram,

We have the latest FPGA accelerated gemm and gemv software API. See the example usage of gemv from the following link:
https://github.com/Xilinx/Vitis_Libraries/tree/master/blas/L3/examples/gemv

You can follow the instructions from the link below to try them on Nimbix with our Alvel U200 card.

Thanks,

Hello Lisa,

Thanks for the response and pointers about the latest API. I will check it out. Meanwhile I am able to resolve the issue with my implementation of GEMV. (I had to explicitly pass GEMX_runGemv=1 GEMX_runGemm=0 to the make command during build). If you any recommendation about the optimal values of the block buffer size of the GEMV engine, kindly let me know.

One reason I wanted to stick to gemx-2017.4 was because it seems more suitable and easily extendable for my requirement. For my requirement, once I have the GEMV implementation tested, I want to extend it to implement the GRU kernel which the genomics tool uses. Please refer the grumod_step function this module which invokes GEMV. [link]

Hope this sounds feasible and in the right direction.

Cheers,
Ram
