No example of using hardware path #11

Open optimistyzy opened 2 years ago

optimistyzy commented 2 years ago

From the current examples, there is no detailed guide and code on how to use the hardware path.

Hello @optimistyzy, thank you for raising an issue. It seems for me that Job API examples are completely unusable in the current state, they definitely should be reworked.

As for High Level API examples, the only change that is required to run hardware path is change the line:

using execution_path = dml::software;

to:

using execution_path = dml::hardware;

In any case, I added the issue to bug tracker.

Thanks. From my usage experience, (1)It still needs some make file or cmake change if we use the hardware path. (2) Configuring wqs by idxd-config.

So better to add this to make it clear.

There is a part of REAMDE.md which describes how to build the library with hardware path enabled. That extra step is likely to be removed in future releases.

Regarding configuration, the library relies on idxd-config documentation, which is linked in reference manual.

@EgorKupaev I know this. What I means that we at least need a example to use hw path with a very simple description.

@EgorKupaev man, I also need a quick example that can run over HW path. as I am new to DSA, I do not know how many places code I need change to make this happen. and also I also need one example copy from DRAM to pmem

Hi @gaowayne, just wanted to let you know that we're working on improving this area for DML. We've extended Quick Start to provide some instruction on how to change current examples, so that they could be offloaded to accelerator, and additionally would be providing an option to specify execution path as input parameter for examples executables. Hope this would make in clearer.
