Subroutines

dev_alloc_report

Write the live structured allocations (address, bytes, device, label) and a summary line, e.g. at teardown to find leaks. Backend independent: it reads the allocation registry, it does not query the device runtime.

subroutine dev_alloc_report(unit)

Arguments

Name	Type	Intent	Attributes	Description
unit	integer(kind=I4P)	in	optional	Output unit (default standard output).

Call graph

dev_get_alloc_stats

Return the number and the bytes of live structured device allocations, i.e. made by dev_alloc/dev_alloc_replace and not yet released by dev_free, optionally only those living on one device. Backend independent: it reads the allocation registry, it does not query the device runtime.

subroutine dev_get_alloc_stats(allocs, bytes, dev_id)

Arguments

Name	Type	Intent	Attributes	Description
allocs	integer(kind=I8P)	out	optional	Number of live allocations.
bytes	integer(kind=I8P)	out	optional	Bytes of live allocations.
dev_id	integer(kind=I4P)	in	optional	Count only allocations living on this device.

Call graph

save_memory_status

Save the current device-memory status into a file. File is accessed in append position.

subroutine save_memory_status(file_name, tag)

Arguments

Name	Type	Intent	Attributes	Description
file_name	character(len=*)	in		File name.
tag	character(len=*)	in	optional	Tag of current status.
