Meeting minutes 2019 05 24 - Geant-RnD/ExascaleProxyDocuments GitHub Wiki

Attendees: Philippe, Seth, Yunsong, Guilherme.

Yunsong: Not much since the hackathon.

Philippe: I merge the result of hackathon. cdouble_t or fmdouble_t.

Philippe: logging then throwing. If the logger does not do the throwing what is the best pattern.

Seth: I think the message can be build outside the logger and then pass to an exception and whomever catch the exception can log the message. See https://geant-ecp-proxy.slack.com/archives/CDY9KFJRH/p1558712626000400 and https://geant-ecp-proxy.slack.com/archives/CDY9KFJRH/p1558712824000900

Soon: RAS

Guilherme: Learned about Singularity and conversion between Docker and Singularity (requires root access on linux). Then I decided to do the conversion with the Docker environment and its worked. Now I have to upload the image and then get access to it from the cluster. Sylab is the repository. I needed a create a token. I could also have used the Sylab cloud to do the conversion. But it also require the token and it is not working for me, I am in contact with the Singularity team to resolve that issue.

Philippe: Couldn’t you just ‘copy’ the file to the cluster?

Guilherme: Maybe, I did not check into it. The singularity image is 2.3 Gb.

Soon: Maybe we should just build directly.

Guilherme: I am almost there with running and learnt a lot about Docker and Singularity.

Seth: RAS.

Philippe: Meeting next week (5/31)
