"Hi , I had recently installed DS5 and ran the matric multiplication application from SVE examples , since I had chosen the N1 as the FVP environment, I observed the vector length was 8 x 64 bits(since application had float 64 as datatype) = 512 bits. I am exploring more on how to force to use the predicate register to utilize the 2048 bits in SVE2 platforms "
DS-5 is a very old toolchain. It has long been superceded by Arm Development Studio, which includes Neoverse N1 (and N2) FVPs and examples:https://developer.arm.com/Tools%20and%20Software/Arm%20Development%20Studio
