htop -u portage shows high cpu usage and low memory usage (something |
| 13 |
like less than 2%). |
| 14 |
|
| 15 |
if I use this instead of htop: |
| 16 |
# grep -m1 ^MemFree /proc/meminfo |
| 17 |
MemFree: 253332 kB |
| 18 |
|
| 19 |
I get for -j1: |
| 20 |
mean = 397662.00592 |
| 21 |
min = 196772 |
| 22 |
max = 762304 |
| 23 |
std = 161394.91895 |
| 24 |
|
| 25 |
I have put up data from some -j4 runs at: |
| 26 |
http://aspodata.se/tmp/R/ |
| 27 |
where mem4* are made with ./memwatch.pl > mem4_<run#>.log. It's columns are |
| 28 |
just seconds, MemFree, and MemAvailable, taken from: |
| 29 |
|
| 30 |
$ head -3 /proc/meminfo |
| 31 |
MemTotal: 6103628 kB |
| 32 |
MemFree: 1028012 kB |
| 33 |
MemAvailable: 2326588 kB |
| 34 |
|
| 35 |
/// |
| 36 |
|
| 37 |
from mem4_<run#>.log, I see that the minimum free memory is: |
| 38 |
run 1 203492 |
| 39 |
run 2 202392 |
| 40 |
i.e. about 200MB. |
| 41 |
|
| 42 |
build_1.log points the finger to sandbox. So it might be that there |
| 43 |
i no problem at all with R, it might be that sandbox doesn't work here. |
| 44 |
I don't know what sandbox requires from the kernel so there might be |
| 45 |
some syscall missing. |
| 46 |
|
| 47 |
I did run 2 as |
| 48 |
FEATURES="-sandbox -usersandbox" emerge -aqv1 dev-lang/R |
| 49 |
|
| 50 |
In build_2.log it just says Segment fault in the vincinity of |
| 51 |
NEWS.2.rds, NEWS.rds, base.Rdts, and methods.Rdts. The first |
| 52 |
two is mentioned in doc/Makefile, and the latter two in |
| 53 |
src/library/Makefile. Going into doc and src/library and makeing |
| 54 |
thoose four works without any errors. |
