Ende des Supports fuer den Modem/ISDN-Zugang des LRZ
by LRZ aktuell Jan. 19, 2011

Jan. 19, 2011

Als ein Relikt aus vergangenen Zeiten betreibt das LRZ noch einen Zugang ueber das Fernsprechnetz mittels Modem oder ISDN-Adapter. Die Rufnummern sind dabei (089) 35831-9000 (Telekom) und (089) 89067928 (M-net). Die Modem/ISDN-Einwahl wird seit Jahren immer weniger genutzt. Da die eingesetzte Server-Hardware in die Jahre kommt und das Know-How unseres Personals zu dieser Technik abnimmt, haben wir uns entschlossen, die offizielle Unterstuetzung fuer den Modem/ISDN-Zugang zum 31. Maerz 2011 einzustellen. Nach diesem Termin wird der Dienst zwar weiterlaufen, bei Problemen oder Geraeteausfaellen erfolgt aber keine Fehlerbehebung und keine Beratung mehr. Wir empfehlen allen Anwendern, die noch den Modem/ISDN-Zugang des LRZ nutzen, auf einen kommerziellen Internetanbieter zu wechseln. Stand der Technik ist dabei ein Breitbandzugang ueber DSL, Fernsehkabel oder Mobilfunk (UMTS). Wer trotzdem noch den Zugang ueber Modem oder ISDN verwenden will, kann diesen auch ueber einen kommerziellen Anbieter konfigurieren. Eine Uebersicht von "Internet-by-Call"-Providern findet man z.B. auf der Seite http://www.billiger-surfen.de/isdn-analog-internet/. Falls der Zugang auf einen LRZ- oder Uni-internen Dienst eine interne Netzadresse erfordert, ist eine VPN-Verbindung aufzubauen. Informationen und Anleitungen zu VPN stehen auf der Seite http://www.lrz.de/services/netz/mobil/vpn/.

PRACE preparatory access projects
by LRZ aktuell Jan. 19, 2011

Jan. 19, 2011

Dear HLRB-users, we would like to bring to your attention the possibility of receiving application enabling grants from PRACE, the Partnership for Advanced Computing in Europe (www.prace-project.eu) The regular calls for computing resources on the two Tier-0 systems in Europe are intended for codes that are "petascale" ready. Additionally, there is a continuous call for preparatory access allowing researchers to apply for code scalability testing, support for code development and optimisation. This call aims at researchers that need to optimise their codes before responding to project calls and gives them the possibility to improve their codes together with PRACE software experts. In case you are interested in submitting a proposal, please get in contact with LRZ personnel through hlrb-admin_at_lrz-muenchen.de. We will assist you in the preparation and submission of the proposal. For more information, please see: http://www.prace-project.eu/news/ prace-research-infrastructure-announces-a-continuous-call-for-preparatory-access. This information is also available on our web server http://www.lrz-muenchen.de/services/compute/hlrb/aktuell/ali3922/ Matthias Brehm
