This page collects information about surveys relevant to the EGI Opreations Community and the EGI Technology Providers (such as EMI, IGE, etc.). Surveys are conducted to collect information about deployed software, oprational tools and generally speaking to collect feedback from Resource Infrastructure Providers and Resource Centres.
Priorities and usage of deployed software
- Release date: 06 March 2012
- Deadline for submission: 20 March 2012
Platform and software deployment plans
- Release date: 06 March 2012
- Deadline for submission: 20 March 2012
Overview
Grid software is being provided for multiple OS platforms. For example, the number of platforms supported will increase with EMI 2.0, which is expected in Spring 2012: in EMI 2.0 it is expected that all products will be released for sl6, and a subset also for Debian. EGI operations consequently need to review the list of early adopter sites, to make sure that staged rollout resources are allocated for testing of software on the platforms of interest.
All Resource infrastructure Providers are requested to consult with their site managers to define their priorities. Please provide your feedback according to the instructions below.
Instructions
Please participate to this survey by supplying your input survey_platform

(CLOSED) NGI International tasks and EGI Global Services
- Release date: December 20 2011
- Deadline for submission: January 19 2012
(Overview NGI International Services
NGIs are requested to perform a self-assessment of the NGI operational services.
- Question 1-7: NGIs are requested to assess the operations international tasks of the NGI/EIRO. The NGI representatives are required to fill in the tables providing an estimation of the current manpower needed to run the service and a written report of the main activities carried out in 2011. Note well: the manpower requested to be estimated is the TOTAL one, including EGI-InSPIRE funding and local sources of funding as applicable.
- Question 8: NGIs are requested to provide feedback about three areas of improvement of operations for 2012
- Question 9-11: NGIs are requested to estimate the level of internal funding for NGI operations already secured after the end EGI-InSPIRE
Instructions
- Please, submit your survey at NGI Int. Services survey
Overview: EGI Global Services
NGIs are requested to assess the performance of EGI.eu Global Services (operational ones). Input provided will be used for the yearly assessment of EGI Global Services in 2012 (milestone MS115). The survey addresses all operations Global Services, these are devided into four categories:
- PART I Infrastructure services and tools (central instances)
- PART II Grid services: release and deployment
- PART III Support
- PART IV Operations management and coordination
Instructions
- Please, submit your survey at EGI Global Services survey
Results
(CLOSED) SLURM support for CREAM
- Release date: November 25 2011
- Deadline for submission: December 14th 2011
Overview
This survey is addressed to sites deploying gLite middleware to assess the interest in getting support of the SLRUM batch system in CREAM (the batch systems currently supported are LSF, PBS/Torque, SGE, this list does not include SLURM currently).SLRUM was reported in our community to be a viable replacement of PBS/Torque especially in large stes, thanks to its scalability and good functional capabilities.This survey aims to collect feedback from site managers in order to assess the need for support of SLURM in CREAM.We invite all sites deploying CREAM or who are planning to deploy CREAM, to participate to this survey (please coordinate participation internally and make sure that a single reply is submitted per site).The survey includes five questions, all in one page.
Instructions
- Please, submit your survey using the online form.
Results
39 Sites would consider to replace their LRMS with SLURM if supported by CREAM
- Total of 64600 cores (17% of the job slots available in the infrastructure)
- 23 sites with more than 1k cores
If you are planning a replacement of the current batch system, what are the reasons for this?
- 35 - Improve the scalability and the stability of the LRMS
- 20 - The set of features of the current batch system are not sufficient
- 15 - The new batch system would be easier to deploy and manage
- 5 - Migrate from a costly solution to a free, open source, one
Note: Multiple answers were allowed

(CLOSED) LB capabilities, service management and auditing and gLite-CLUSTER
- Release date: 18 Jan 2011
- Deadline for submission: 10 Feb 2011
Overview
- PART 1, Logging and Bookkeeping Service: Logging and Bookkeeping (LB) it is a monitoring service which gathers, aggregates and archives information on infrastructure behaviour from the perspective of users' tasks. The EMI project aims at extending the LB scope and its further integration with other grid services. The first page of the survey contains a set of questions to help LB Team to better design the new features of the LB Service, and to target the real users' needs.
- PART 2, Remote Grid Service Management (RGSM). Management is performed through a set of notifications issued to the relevant Grid service instance. Examples of management actions are: start, stop, drain etc. The RGSM framework can be used for remote management of a service. EMI has a dedicated task force to investigate the requirements for common service monitoring and management interfaces. This survey is to collect information and requirements from the EGI operations community and sites to understand which technologies are of interest for service management.
- PART 3, Grid service auditing (GSA), that is a feature that allows a system administrators and users to check the status of a service in terms of load, length of internal queues, and to monitor service workload from a grid point of view over time. Service auditing is different from Nagios-based monitoring as it is not based on probes, but rather on the periodic gathering of service status information.
- PART 4, gLite CLUSTER, glite-CLUSTER allows the configuration of information related to the batch system environment to be separated from the configuration of the job submission interface. With this service sites will be able to publish their resources information consistently and without any workaround. Even in case of multiple CEs or cluster with heterogeneous hardware configuaration. There are few questions to understand how the publishing of cluster information is a problem for site managers.

(CLOSED) top-BDII deployment scenarios
- Release date: May 24th 2011
- Deadline for submission: June 30th 2011
Overview
Survey addressed to NGIs
Results

- Yes 17 94%
- No 1 6%
Q2: If not, are you planning to deploy one?
- Yes 2 40%
- No 3 60%
Q3: Your NGI current top-BDII deployment
- Without High Availability and/or Load Balancing 6 35%
- With HA or LB, describe your solution 11 65%
Q4: Are you using failover at the client side using the top-BDII of another NGI?
- Yes 1 6%
- No 17 94%
Q5: Number of sites using the current top-BDII of your NGI
- Unknoun 1 6%
- From 1 to 5 7 39%
- From 6 to 10 2 11%
- From 11 to 15 4 22%
- From 16 to 20 2 11%
- From 21 to 25 0 0%
- From 25 to 30 0 0%
- More than 30 2 11%
Q6: Top-BDII is a critical service that needs to be highly available. Various strategies to improve the robustness of the service are possible, such as a load balancing configuration implementing a cluster of top-BDIIs (within your infrastructure or shared with other Resource Infrastructures), or by deploying a list of alternative top-BDII instances at the client side. Both scenarios are mostly beneficial to small/medium NGIs where the amount or resources may not justify the deployment of an own top-BDII cluster. Are you interested in this? In case of sufficient interest, EGI can put effort in the definition of a top-BDII deployment model that addresses these needs.
- Yes 9 56%
- No 7 44%
