Re: [android-building] Memory leak?

2020-04-30 Thread 'Dan Willemsen' via Android Building 
The minimum requirements for the build is 16GB of RAM available (and even
with that it can be difficult later in the build). The virtualization
mention was meant to say that a machine with 16GB of RAM wasn't enough when
virtualizing -- the virtual machine would need 16GB allocated to it.

`m -j1` means that we'll only launch a single process at a time, but many
of those spin up a number of threads on their own. Parallelism can have
some effect on peak RAM use, but I wouldn't expect that to significantly
affect things, at least for soong_build.

Which target you're building can have a reasonably big impact on RAM usage
(as 64-bit targets need both 64 and 32 bit configurations). On my machine
with aosp-master:

 aosp_cf_x86_phone - soong_build peaks at ~6GB  (and allocated ~20GB over
its lifetime). next, kati takes ~4GB
 aosp_crosshatch - soong_build peaks at ~8.5GB  (and allocated ~26GB over
its lifetime). next, kati takes ~6GB

For some of our larger branches/targets, I've seen peaks at >14GB (~50GB
lifetime allocs), with kati using >10GB.

same problem with 2 processes and I have only 8 GB of physical RAM and it
is not virtualized system . any timing for fix ?

I understand this might have something to do with parallelism, but I run
make with -j1 and soong_build is still running multiple threads.

[android-building] Memory leak?

2020-04-30 Thread Silver Rampart 
When running a normal build, process soong_build quickly fills up all 
available memory (6GB in under 5 minutes) and starts to swap. Quad-core i5. 
I understand this might have something to do with parallelism, but I run 
make with -j1 and soong_build is still running multiple threads.
