The National Infrastructures for Research and Technology (GRNET S.A.) provides resources on the ARIS supercomputing system for the execution of preparatory computational projects.<\/p>\n
The call for preparatory projects on the ARIS system is continuously open for proposals. These proposals are reviewed by GRNET’s technical committee.<\/p>\n
Note: The evaluation of proposals is a continuous process and researchers should expect results within 10 working days from the date of submission of their application.<\/p>\n
Selected projects begin up to one month after their evaluation date.<\/p>\n
The call for preparatory projects aims to give researchers working at Greek educational or research institutions access to the ARIS system for the purpose of:<\/p>\n
The primary objective of providing access for preparatory projects is to allow researchers to test their codes and applications in order to strengthen their applications for production project calls.<\/p>\n
Types of preparatory projects:<\/p>\n
Type A: Code scaling tests<\/b><\/p>\n
Type A preparatory projects aim to create performance graphs of code and data on the ARIS system, allowing researchers to use them in their applications for production projects.<\/p>\n
The maximum access duration for Type A projects is 2 months, while the maximum number of core hours provided is 50,000 core hours on the Thin node island, 25,000 core hours on the GPU island, and 25,000 core hours on the Fat Node Island. The total number of core hours that can be requested must not exceed 50,000 core hours. On all islands, core hours are counted at the CPU level<\/span>.<\/p>\n After the 2-month period, and within 30 days, researchers must send GRNET a report on the execution and results of the preparatory project, based on the procedure described here<\/span><\/a>.<\/p>\n Type B: Code porting and optimization<\/b><\/p>\n Type B preparatory projects aim to give users access to the system for the purpose of porting and optimizing their code so that it operates efficiently on the ARIS system. Users must include in their application a detailed development plan, including information about the human resources available to the project and their technical skills.<\/p>\n The maximum access duration for Type B projects is 4 months, while the maximum number of core hours provided is 50,000 core hours on the Thin node island, 25,000 core hours on the GPU island, and 25,000 core hours on the Fat Node Island. The total number of core hours that can be requested must not exceed 50,000 core hours. On all islands, core hours are counted at the CPU level.<\/p>\n
