Search help

Note: Searching from the top-level index page will search all documents. Searching from a specific document will search only that document.

Find an exact phrase: Wrap your search phrase in "" (double quotes) to only get results where the phrase is exactly matched. For example "PyTorch for the IPU" or "replicated tensor sharding"

Prefix query: Add an * (asterisk) at the end of any word to indicate a prefix query. This will return results containing all words with the specific prefix. For example tensor*

Fuzzy search: Use ~N (tilde followed by a number) at the end of any word for a fuzzy search. This will return results that are similar to the search word. N specifies the “edit distance” (fuzziness) of the match. For example Polibs~1

Words close to each other: ~N (tilde followed by a number) after a phrase (in quotes) returns results where the words are close to each other. N is the maximum number of positions allowed between matching words. For example "ipu version"~2

Logical operators. You can use the following logical operators in a search:

+ signifies AND operation
| signifies OR operation
- negates a single word or phrase (returns results without that word or phrase)
() controls operator precedence

14. gc-memorytest

This tool tests all the tile memory in an IPU, reporting any tiles that fail.

To use it, run:

gc-memorytest -d {device_id}

where {device_id} is the id number returned by the gc-inventory tool. If the test reveals no issues with the device memory, the output will look like this:

{
  "result": "pass"
}

If the test reveals any issues with the device memory, the output shows which tiles have failed, and looks like this:

{
  "tile_results": [
    {
        "12": "fail"
    },
    {
        "1000": "fail"
    },
    {
        "0": "fail"
    }
  ],
  "result": "fail"
}
