v4 v5 21 21 22 22 == Benefit == 23 - Single Scheduling Environment for both High Performance Computing (HPC) resources [Grids] and Volunteer Resources24 - Validation of work units -- Due the homogenous nature of HPC/Grids it is thought that they are more reliable than volunteer resources; however even in these environments data corrupt occurs (system failure, administrative outages, etc)23 - Single Scheduling Environment for both High Performance Computing (HPC) resources [Grids] and Volunteer Resources 24 - Validation of work units -- Due the homogenous nature of HPC/Grids it is thought that they are more reliable than volunteer resources; however even in these environments data corrupt occurs (system failure, administrative outages, etc) 25 25 26 26 == Problems == 27 27 There are some pit falls that have been identified by uses BOINC on some Grid computing systems. Most of the problems identified in this session dealt with HPC/Grid Submission Systems and efficient use of Grid resources (allotted grid computing hours). 28 - Problem 1: Scheduled Grid client runs when server has no work28 - Problem 1: Scheduled Grid client runs when server has no work 29 29 The client would be idle burning time from the users allotted computer hours. 30 - Problem 2: Grid Scheduler kills jobs after time expires30 - Problem 2: Grid Scheduler kills jobs after time expires 31 31 Even with check pointing data processed on the last WU would be lost. The workspace would be scratched. 32 32 … … 34 34 Incorporate some mechanism into the BOINC client to make it aware to a limited runtime environment. 35 35 Potential Fixes: 36 - EndOnNoWork Parameter36 - EndOnNoWork Parameter 37 37 If no work is available from the servers the BOINC client would end instead of deferring communication. 38 - MaxWUCount Parameter38 - MaxWUCount Parameter 39 39 After the max number of WU are reached; the new client would not request new work and then end gracefully.
