def match_nvidia_architecture(conditions_dict, architecture):

"""
|
|
Match Nvidia architecture against condition dictionary.
|
|
|
|
Args:
|
|
conditions_dict: dict with condition strings as keys, parameters as values
|
|
architecture: int representing architecture (e.g., 89 for Ada Lovelace)
|
|
|
|
Returns:
|
|
list of matched parameters
|
|
|
|
Condition syntax:
|
|
- Operators: '<', '>', '<=', '>=', '=' (or no operator for equality)
|
|
- OR: '+' between conditions (e.g., '<=50+>89')
|
|
- AND: '&' between conditions (e.g., '>=70&<90')
|
|
- Examples:
|
|
* '<89': architectures below Ada (89)
|
|
* '>=75': architectures 75 and above
|
|
* '89': exactly Ada architecture
|
|
* '<=50+>89': Maxwell (50) and below OR above Ada
|
|
* '>=70&<90': Ampere range (70-89)
