In order to enable an iCal export link, your account needs to have a key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
In conjunction with a having a key associated with your account, to have the possibility of exporting private event information necessitates the creation of a persistent key. This new key is also associated with your account and whilst it is active the data which can be obtained through using this key can be obtained by anyone in possession of the link provided. Due to this reason, it is extremely important that you keep links generated with this key private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately remove it from 'My Profile' under the 'HTTP API' tab and generate a new key before regenerating iCalendar links.

Workshop on adapting applications and computing services to multi-core and virtualization
from to (Europe/Zurich)
at CERN ( 40-S2-A01 )
at CERN ( 40-S2-A01 )
Preparatory workshop towards drawing up a roadmap for providing IT services which allow LHC experiment applications to exploit multi-core and virtualization capabilities. Applications being developed to exploit new hardware architectures and virtualization technology impose new requirements on the computing services provided by the local computer centers or by the Grids. The goal of this workshop is to discuss these new requirements and to have a first exploration of the possible solutions that service providers could offer to the LHC experiments. Contacts: Pere Mato (CERN) , Predrag Buncic (CERN) , Vincenzo Innocente (CERN) , Denise Heagerty (CERN) EVO conference has been booked at Universe community 24-June: http://evo.vrvs.org/evoGate/koala.jnlp?meeting=M2MvMB2a2iDaDn9I9lDM92 25-26 June: http://evo.vrvs.org/evoGate/koala.jnlp?meeting=M9MIMi2e2BDeD89e99DD99

Using Linux KVM and KSM in scientific computing environments
Linux as Hypervisor with KVM is particularly performant virtualization technology to use in scientific computing environments, thanks especially to its (out of sync) secondary MMU management of the shadow page tables and it support for CPUs with EPT or NPT. In addition KVM leverages: the efficiency, testing and reliability of the huge pool of Linux Kernel device drivers, the close integration of the KVM shadow page tables management with the Linux Virtual Memory subsystem that allows KVM to take advantage of kernel features like swapping and KSM in a fully transparent way and much more.

Scheduling for mixed parallel and sequential workload
The talk will cover various techniques within the LSF Workload Management system for promoting higher efficiency with a non-homogeneous workload: - How to guarantee that parallel jobs can run in a mixed sequential/parallel environment (slot reservation /memory reservation/backfill) - How to maximize the efficiency on multicpu/multicore machines by using CPU binding - How to maximize the efficiency of very short jobs by using sub-scheduling (Session Scheduler) - How to maximize the efficiency of memory usage - How to maximize the efficiency of distributed parallel jobs: taking in account the compute farm topology

Next generation of virtual infrastructure with Hyper-V
Internet Services group provides the hardware and OS layers for services operated by different CERN organizational units. Within this framework, a user can ask for a new virtual server from a web browser and have it ready within 15 minutes. The latest release of the virtual infrastructure is based on Hyper-V, Microsoft Virtual Machine Manager, management SOAP web services and user web interface. This talk will present this approach and will discuss the evolution of the Microsoft Hypervisor from the perspective of both the end-user and the system administrator.
Speaker: Juraj Sucik (CERN) Material: Slides
Virtualisation from a security perspective
A look at some of the security issues around virtualization, covering both newly-added concerns as well as potential security benefits from using virtualization.
Speaker: Jan Iven (CERN) Material: Slides
Possibilities and limitations of virtualization from a networking perspective
This talk will address: types of networks for data centers and their impact on VM deployment, IPv4 address space limitation, VM migration and network infrastructure/services to support VMs at CERN.
Speaker: Jose Carlos Luna Duran (CERN) Material: Slides
Virtualisation of Batch Services at CERN
In this talk we will present a load-driven virtual machine provisioning mechanism based on Platform Virtual Machine Orchestrator (VMO). LSF and VMO are coupled to manage virtual machines that meet the requirements of the jobs. The underlying infrastructure uses Quattor/LANDB/CDB and LEMON monitoring which makes this virtual machine prototype compatible with the existing operations procedures.

EGEE MPI working group
In the original LHC Computing Grid, it was not possible to run parallel jobs which rely on communication between concurrent processes. Upon request of the user community, an MPI implementation on the Grid has been created. Recently, an MPI working group has been setup to investigate the bottlenecks with this MPI implementation both for system administrators and for users. Another task of this working group is to write recommendations for improvements and extensions. One of the extensions is a the mechanism for the user to request all cores on a single node.
