Enol is in holidays. Doc effort is already done, save some work for next week. The docs are splitted in two, for admins and users. * Another task is the nagios probes. SA3 should provide probes in 3 weeks time, they are working also in EMI. * After these weeks, Emir will test and verify them, and eventually move them to production. * Gonçalo submitted a report. - Task 2: Nagios probes (Emir Imamagic/John Walsh/Enol Fernandez/Paschalis Korosoglou) * Gergely: Who will integrate the probes on NAGIOS boxes. * Alvaro: We have those boxes on the SA2 verif testbed, and also Emir. The probes would be tested on it. * Gergely: Will there be NGI specific tests? * Alvaro: Yes, I have to ask Emir about the contribution of those NGIs to this verification effort. * Gonçalo: If these probes pass the test, there is a procedure to include them in production, that includes OMB. So it is documented. * Alvaro: Yes, it is in the wikipage. * Gonçalo: SA3 developed the probes since EMI felt they were not their responsability. * Gergely: I want to know who is responsible for the development. * Alvaro: It is SA3. * Peter: Could you summarize the scope of the probes. * Alvaro: The current nagios probes only check 2 slots and do a very simple "Hello World" program. The new probes check for BDII misconfigurations, checks more slots: https://wiki.egi.eu/wiki/VT_MPI_within_EGI:Nagios - Task 3: Information system (Gonçalo Borges) * Alvaro: Gonçalo, can you summarize your report. * Gonçalo: Yes, the report is in https://wiki.egi.eu/wiki/VT_MPI_within_EGI:Nagios. This task checks what could be available on each sites, checking each CE for MPI support, and then the information produced by those CEs. It detects incorrectly formated tags, incorrect paramaters and configuration. We will forward this info to Operations. * Gergely: Peter says fine, but how these checks guarantee that sites don't break six months later. * Gonçalo: The script should be run regularly, monthly, for example. * Gergely: What is the time frame for these probes to be in production? * Gonçalo: This does not depend on us, it depends on Operations. * Alvaro: Peter, do you know what timeframe we are talking of?. * Peter: There are several step involved, including the Operation Dashboard, A/R and OMB so it should take a few months. * Alvaro: Perhaps at the end of the year? * Peter: It depends on many factors. * Gergely: What sites are publishing wrong information?. Only the MPI VOs. * Gonçalo: I only checked information offered for the sites, it is independent of the VO. * Gonçalo details another time the type of publication errors and misconfigurations detected. Some are caused by the underlying batch system. * Alvaro: Roberto develops for the SGE and sent a request to EMI * Roberto: Yes, I sent and update request. - Task 4: Accounting system (John Gordon/Iván Díaz) * Alvaro: John is not here. The information collected from the bathc system must be sent to the APEL people. The usage records must be modified to support MPI. * Currently only the efficiency is recorded. * We have to track many requests about accounting. * Roberto will open a savannah requirement for EMI. * The request is different that the one for the information system one. - Task 5: Batch system status (Roberto Rosende/Enol Fernandez) * Enol submitted a report about the test of Grid Engine and Torque. EMI 2 will include a bug free version of Maui. This pacakages must be verified first. - Task 6: Gather information from MPI sites (Zdenek Sustr) * Zdenek: We have enroled a new user in April. We updated documentation and fixed site instalation. We are working on some problems with CESGA testbed. I think we have progressed far. * Zdenek: We don't know if those problems are due to the documentation or some problem with our side. * Alvaro: We will look into that. * Gergely: Can we open a ticket to track this. * Zdenek: We have one on a NGI local system. * Alvaro: We will maintain resources for the MPI VO for the foreseeable future. MPI VT report 15' -------------------- * Alvaro asks about the best format. * Gergely suggest to structure the report on 6 areas and assign responsable groups for each. He will circulate notes with open actions on these areas. * Gergely proposes giving a month deadline for each area leader. * All agree on a demo for the Technical Forum. * Discussion about the decomission and future of the mailing list. * Gergely proposes to use the mailing list to coordinate the report and TF demo. * Rescheduled to the end of June.
