| HPCREL 1: How do you manage AWS service limits for your accounts? |
|---|
AWS sets service limits (an upper limit on the number of each resource your team can request) to protect you from accidentally over-provisioning resources.
HPC applications often require a large number of compute instances simultaneously. The ability and advantages of scaling horizontally are highly desirable for HPC workloads. However, scaling horizontally may require an increase to the AWS service limits before a large workload is deployed to either one large cluster, or to many smaller clusters all at once.
Service limits must often be increased from the default values in order to handle the requirements of a large deployment. Contact AWS Support to request an increase.
