 atemu12 | lol | 10:39:59 |
| atemu12 | The AOSP is quite a beast | 10:40:08 |
 raitobezarius | good good | 10:40:22 |
| raitobezarius | I will try to avoid shooting myself in the foot | 10:40:27 |
| atemu12 | Ccache helps a lot | 10:40:44 |
| atemu12 | Cuts down the time of a second build by ~1/2 | 10:40:57 |
| atemu12 | My upgrade a few days ago after 5 months or so only took 1h with it | 10:41:26 |
| raitobezarius | Interesting | 10:41:32 |
| atemu12 | * Even my upgrade a few days ago after 5 months or so only took 1h with it | 10:41:34 |
| raitobezarius | I am just afraid the EPYC 7762 doesn't have enough RAM for driving the build | 10:41:45 |
| atemu12 | 32G is plenty | 10:41:55 |
| atemu12 | You can even do it with 16G with some zram cache | 10:42:17 |
| atemu12 | It was a few years ago that I did this though | 10:42:32 |
| atemu12 | * You can even do it with 16G with some zram swap | 10:43:21 |
| raitobezarius | but doesn't the memory consumption scale with the number of cores? | 10:46:38 |
| raitobezarius | is the build very parallel or not? | 10:46:41 |
| atemu12 | It's very parallel indeed | 10:47:15 |
| atemu12 | I can't tell you how much it requires with more than 8 cores though | 10:47:33 |
| atemu12 | *16 Threads | 10:47:49 |
| raitobezarius | yeah I have 128T | 10:48:17 |
| atemu12 | And how much RAM? | 10:48:33 |
| raitobezarius | 128G | 10:50:18 |
| raitobezarius | but soon 256G | 10:50:20 |
| atemu12 | I'd give it 32-64G of zram swap to be sure but it's probably fine | 10:50:52 |
|  @jusc140a:tu-dresden.de left the room. | 12:56:05 |
|  pbsds changed their display name from pbsds (UTC+1) to pbsds. | 14:54:58 |
| raitobezarius | Yeah I guess | 16:31:40 |
 samueldr | In reply to @atemu12:matrix.org
32G is plenty as long as you don't use tmpfs on tmp | 18:02:56 |
| atemu12 | samueldr: Good point, build directory should be on disk for this | 18:06:03 |
| raitobezarius | yeah | 23:20:23 |
