Tips & Tricks¶
Scaling a ProcSet
¶
Assuming a ProcSet
represents a set of processors with many
cores, one may create the set of cores with the following snippet:
def upscale(pset, factor):
return procset.ProcSet(
*map(
lambda itv: (itv.inf * factor, (itv.sup + 1) * factor - 1),
pset.intervals()
)
)
Dumping to JSON¶
The ProcSet
object does not provide a JSON serialization
method.
The main reason for this is that the canonical string representation is enough
to store all the information, and allows for portability of the serialization.
The following snippet might come handy to export a ProcSet
to
JSON.
import json
import procset
class ProcSetJSONEncoder(json.JSONEncoder):
def default(self, obj):
if isinstance(obj, procset.ProcSet):
return str(obj) # use canonical string representation
return json.JSONEncoder.default(self, obj)
json.dumps({'alloc': procset.ProcSet((0, 3))}, cls=ProcSetJSONEncoder)
For more advanced usages, see the standard module json
, or the
third-party package jsonpickle.
