Without announcing participation on the mailing list, I contacted Sean to get the challenge file.
|
||||
I prepared a fresh Qubes OS 4.0 rc3 install on an Intel(R) Core(TM) i7-4550U CPU.
|
||||
The actual computation were done on Fedora 25 AppVM (Linux version 4.9.56-21.pvops.qubes.x86_64 (user at build-fedora4) (gcc version 6.4.1 20170727 (Red Hat 6.4.1-1) (GCC) ) #1 SMP Wed Oct 18 00:22:42 UTC 2017).
|
||||
I installed the rust, rust-std and cargo binaries from the OS repositories:

=========
|

$ cargo run --release --bin compute

|
||||
The BLAKE2b hash of `./response` is:
|
||||
c1551793 c699de37 037ea020 06adef4a

$ sha256sum ./response

342170430d75c92c199f0606616dfa4112b2dfcb1c96b956b533e680eced8996 ./response
|
||||
|
||||
Postprocessing
|
||||
==============
|
||||
I saved the powersoftau repo and dependency crates and the rust, rust-std and cargo rpms.
|
||||
Then I destroyed the VM.
