Print Handler

This handler print the measured energy sample on the standard output

How to Use it

This handler is the default handler. When you use a context manager and decorated function without specifying any handler, the PrintHandler will be used

Example :

with EnergyContext(domains=[RaplPackageDomain(1), NvidiaGPUDomain(0)], start_tag='foo') as ctx:
    foo()
    ctx.record(tag='bar')
    bar()

Output

The previous example will produce the following result on the standard output

begin timestamp : AAAA; tag : foo; duration : BBBB; package_0 : CCCC; nvidia_gpu_0 : DDDD
begin timestamp : AAAA2; tag : bar; duration : BBBB2; package_0 : CCCC2; nvidia_gpu_0 : DDDD2

with :

• AAAA* : timestamp of the measured interval beginning

• BBBB* duration of the measured interval (in seconds)

• CCCC* energy consumed by CPU 0 during the measured interval

• DDDD* energy consumed by GPU 0 during the measured interval
