use system jemalloc #7

Closed Alessandro-Barbieri closed 3 years ago

Alessandro-Barbieri commented 3 years ago

Is it possible to use system jemalloc? Why it need jemalloc built with the nanos6_je_ prefix?

kevinsala commented 3 years ago

The idea is to have a jemalloc only for the Nanos6 library to not interfere with the allocations made by the application. Additionally, the jemalloc installation for Nanos6 must be compiled with --enable-stats a part from the nanos6 prefix (--with-jemalloc-prefix=nanos6_je_).

--enable-stats is on by default on jemalloc since a long time
