• current Makefile doesn track changes to cache policies
• should also incorporate examples and more of them

Hi,

I think that the command used in the example is wrong

./webcachesim trace.txt LRU 30 0 10

Cheers,

When running the following command:
docker run -it -v ~/traces:/trace sunnyszy/webcachesim:v0.2 memc_200m.tr LRU 1099511627776

...I got the following error:

terminate called after throwing an instance of 'bsoncxx::v_noabi::exception' what(): unable to append int64

The program's last output before the error was:
seq: 200000000 cache size: 42863945528/1093075226624 (0.0392141) delta t: 10.03 segment bmr: 0.0250343 rss: 6475599872

Hi,

I'm using the tool with the same warmup and traceFile with a very big number for the cacheSizeBytes and I would expect to see an object hit ration of 1.0. However I get something around to 0.37. How is this explained? (using LRU)

Cheers,
Nik

I got segment fault when using following cmd (seems not so big):
./basic_trace 3000000 50000 1.8 1 5000000000 test.tr
If I reduce the unique object size by a factor of 10, the program will be fine:
./basic_trace 300000 50000 1.8 1 5000000000 test.tr

Hello,

I am trying to run a simple sample with the docker, but it is showing an error:

Command: docker run -it -v Downloads:/trace sunnyszy/webcachesim:v0.1 wiki2018.tr LRU 1099511627776

error: running sanity check on trace: /trace/wiki2018.tr
terminate called after throwing an instance of 'std::runtime_error'
what(): Exception opening file /trace/wiki2018.tr

I am not sure if I am executing the commands correctly.

Could you help me with this, please?
