Hammerblade #101

Open amithmath opened 2 days ago

amithmath commented 2 days ago

I am trying to implement hammerblade example in pynqz2,ultra96v2, and vu47p but it is running out of resources. This issue has been raised in https://github.com/black-parrot-hdk/zynq-parrot/issues/76 but even for ultra96v2 it is running out of resources. Please let me know which board to use. Thanks.

dpetrisko commented 2 days ago

It should definitely fit on vu47p. Perhaps the manycore config is set too large. Do you have a utilization report you can post?

amithmath commented 1 day ago

Following is the report:

ERROR: [DRC UTLZ-1] Resource utilization: LUT as Logic over-utilized in Top Level Design (This design requires more LUT as Logic cells than are available in the target device. This design requires 71984 of such cell types but only 70560 compatible sites are available in the target device. Please analyze your synthesis results and constraints to ensure the design is mapped to Xilinx primitives as expected. If so, please consider targeting a larger device. Please set tcl parameter "drc.disableLUTOverUtilError" to 1 to change this error to warning.)

dpetrisko commented 1 day ago

Can you post the actual reports and not just the error? Would need to see the hierarchical breakdown to see where LUTs are going

Above report is from ultra96v2. There is no vps_zynq_bd.vu47p.tcl in https://github.com/black-parrot-hdk/zynq-parrot/tree/master/cosim/tcl/bd

dpetrisko commented 16 hours ago

Yes, so it should fit on vu47p. There is no vps configuration file as the vu47p is not a zynq part (no PS)

For the vu47p, we use a uart bridge to emulate the PS. You can see the connection here: https://github.com/black-parrot-hdk/zynq-parrot/blob/master/cosim/xdc/board.vu47p.xdc and the cosimulation here: https://github.com/black-parrot-hdk/zynq-parrot/blob/master/cosim/include/bridge/bsg_zynq_pl.h but we haven’t open-sourced a hardware configuration as it’s a fairly custom solution.

For the ultra96v2 that report is indicating it is very close to fitting. Reducing sizes of the structures in the BlackParrot cores may get you there. Take a look at the TinyParrot configuration in the aviary and experiment with reducing branch predictors and caches

amithmath commented 11 hours ago

I am wondering, is there any possibility to port the hardware to Alveo U250 data center card (https://www.amd.com/en/products/accelerators/alveo/u250/a-u250-a64g-pq-g.html), if I can what are the changes to be done? By the way, bsg_manycore accelerator is 32 bit, can one change to 64 bit? If possible, what are the changes to be done?

dpetrisko commented 10 hours ago

These are both very substantial projects.

The U250 has a pynq port, so beginning there and working through the cosim examples is the way to start. Once cosim is working, hardware examples should port in a straightforward manner

There was a student who ported the manycore toolchain to 64b: https://github.com/bespoke-silicon-group/bsg_manycore/pull/720

The hardware would require more changes, but primarily in parameterization. The actual RV64I ISA difference is minimal, especially if only F support is needed

Both projects would require a highly motivated student for likely two+ quarters. Feel free to reach out to discuss funding for these efforts

Thanks let me see.
