Memory usage of VW?
Locked
 
|
Hi, How can I find out how much memory the VW process is using? When I perform this script: ObjectMemory verboseGlobalCompactingGC. CPointerType defaultPointer malloc: 10000000. ObjectMemory verboseGlobalCompactingGC. It says on the transcript: Global garbage collection (please wait)... reclaimed 0.06 Mbytes of data and 0 OTEntries in 0.6 sec. 184.41 Mbytes total; 167.06 Mbytes used, 17.35 Mbytes free. Global garbage collection (please wait)... reclaimed 0.03 Mbytes of data and 0 OTEntries in 0.6 sec. 184.41 Mbytes total; 167.03 Mbytes used, 17.38 Mbytes free. Even though I allocated 40MB of memory, this is not visible in the numbers given by the “global garbage collect” info. They stay the same. In the windows task manager this change in memory usage is visible though. Is there a way to get the exact number of used bytes of the visual works process? I’m running on windows. Thanks, Mark _______________________________________________ vwnc mailing list [hidden email] http://lists.cs.uiuc.edu/mailman/listinfo/vwnc |

With malloc, you allocate a chunk of memory directly from the OS. The
values reported in the Transcript refer to space taken by objects as managed by the VM.

And is there a method (on ObjectMemory for instance) that returns this total value? Not just the objects managed by the VM, but the entire process memory usage?

ObjectMemory class>>dynamicallyAllocatedFootprint

Hi James,
It doesn't seem to work: |p| Transcript cr; show: ObjectMemory dynamicallyAllocatedFootprint printString. p := CPointerType defaultPointer gcMalloc: 10000000. p yourself. Transcript cr; show: ObjectMemory dynamicallyAllocatedFootprint printString. Writes this on the transcript: 215267840 215267840 Even if I change the gcMalloc: argument to something very large, the printed values stay the same, even though the task manager in windows shows that the process is using 600MB of memory instead of the reported 215MB.

So far as I recall, allocating C memory that way should use FixedSpace. But perhaps someone from Cincom engineering can give a more definitive answer than I can.

That's just the memory managed directly by the VM, i.e.: the object
memory. It also includes a couple extra bits like the native code cache and the native stack, but for the most part it's just the space allocated to objects. You can see that in the implementation: dynamicallyAllocatedFootprint "Answer the total size (in bytes) of the dynamically allocated footprint represented by the receiver." ^self edenBytes + (self survBytes * 2) + self largeBytes + self stackBytes + self compCodeCacheBytes + self oldBytes + self permBytes + self fixedBytes On 5/6/2011 5:24 AM, James Robertson wrote: > ObjectMemory class>>dynamicallyAllocatedFootprint > > Just gives the aggregate amount in use. > > On May 6, 2011, at 6:18 AM, Mark Plas wrote: > >> And is there a method (on ObjectMemory for instance) that returns this total value?

It depends... each way has its advantages and disadvantages.
