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

4. Running a Poplar program on your Pod

You are now ready to run your first program on your Pod. The Poplar SDK contains a number of example programs, for example, the program adder_ipu.cpp builds a simple graph to add two vectors together and return the result.

Make a copy of the poplar/examples/adder directory in your working directory
Compile the program:

$ make

Run the program.

It will produce the following output:
$ ./adder_ipu
Creating graph
Building engine
v1 sum = 10
v2 sum = 65

This simple example just runs on one IPU. Further examples and tutorials can be found in the Graphcore GitHub examples repository, such as: Introduction to PopTorch — running a simple model.

See Section 6, Next steps for more information on writing your own programs for the IPU.
