UZH

• hosted site visit from Comp.chem representer from UniPe: Dr. Alessandro Constantini has been visiting UZH for learning and implementing a work-flow use case using the GC3/UZH developed tool GC3Pie.
• Participation in EMI Early Adopter activites for EMI ARC-CE, ARC-client

SWITCH

• Two people are now capable of operating a monitoring instance for an NGI.

2.3. Issues and mitigation

Issue Description	Mitigation Description
CSCS Failure in one of our Lustre scratch servers which made a few jobs to fail immediately and many to get stalled/not queued. We are starting to see excessive rate of failed disks in our Lustre servers (Sun J4400) Suffering random segfaults of Torque pbs_mom process. Batch system Torque did not fail over when it was supposed to do. Still suffering from user jobs doing excessive IO which slows down other jobs running in the shared Lustre o GPFS filesystem.	CSCS Deactivated the Lustre server and removed hung jobs after a long period of time. Replacing disks as soon as we can, but since all disks are of the same age, sooner or later we will have to replace some machines/disks. Contacted Adaptive Computing but not very responsive on this issue. Working on it trying to make pbs_mom to dump core files. Replaced Torque for a newer version. Penalized excessive use of high amount of certain operations (such as hte commands 'find', 'du', etc.).
UZH Validation of EMI ARC components was more complicated than anticipated; fewer EA did actually participate in the test phase Several EMI ARC components did not pass the validation phase	UZH acknowledged by Mario David we had to get back to developers (through several channels) to clarify the issues and bugs.
