20 DOAP Architecture Proposals for object: Migration; Optmized communication; Monitoring PRIMOS – PRIMitives for Object Scheduling

Lishef Grid Workshop - February UERJ, Rio de Janeiro 21 Java versus GRID Benefits of Java to GRID environments: –Code portability simplifies assumptions about the heterogeneous execution environment –Object-oriented programming model straightforward program partitioning –Fast learning curve structured language, no pointers, programming less error prone

Lishef Grid Workshop - February UERJ, Rio de Janeiro 22 PRIMOS: Java meeting the GRID PRIMOS extends Java with mechanisms to support: –remote instantiation and object migration deal with code deployment and accounting –optimized communication primitives access to specialized hardware features not available to usual Java applications –distributed system utilization: probe & publishing –construction of inter-object communication profiles

Lishef Grid Workshop - February UERJ, Rio de Janeiro 23 PRIMOS Architecture Overview Cell groups Cell Network Segment Information Server Hosts

Lishef Grid Workshop - February UERJ, Rio de Janeiro 24 PRIMOS: towards adaptive behavior PRIMOS provides feedback to applications about system state –Additionally to system load indexes, inter- objects communication profiles may be constructed, using lightweight measurements –Per-application heuristics might be used to provide specific adaptive behavior

Lishef Grid Workshop - February UERJ, Rio de Janeiro 25 VIC++ For Access Grid

Lishef Grid Workshop - February UERJ, Rio de Janeiro 26 VIC ++ Access Grid –a Grid for people –people interact with Grid resources –interaction between people groups –distributed seminars, discussions, workshops, classes,...

Lishef Grid Workshop - February UERJ, Rio de Janeiro 27 VIC++ VIC and RAT –software for video and audio transmission –mbone tools –used by Access Grid (also VRVS)

Lishef Grid Workshop - February UERJ, Rio de Janeiro 28 VIC++ Global Supercomputing 2001 –a node at Instituto de Informática - UFRGS Experience results –mbone tools are not easy to operate –they lack some features for adaptation to dynamic environment

Lishef Grid Workshop - February UERJ, Rio de Janeiro 29 VIC ++ –an extension of VIC –two main targets: an adaptability algoritm –adjust the VIC configurations to the network conditions –reduce the work of the operator during a session –to expand the statistics generator of the VIC in order to provide more data to the researcher

Lishef Grid Workshop - February UERJ, Rio de Janeiro 30 Globus Experience Globus installation –Myrinet/PC cluster of II-UFRGS –second semester of 2001 –next steps use with some academic applications - tests evaluate the possibility of integration between our projects and Globus
