Getting Front-End Bound in a modulas operation

439 Views

Hi,

I am using VTune Profile for tuning my code and getting the following:

Retiring=45.4%, FrontenendBound=30%

The line here performs a modulus operation:

currentSegmentIndex = marketDataTries%TOTAL_SEG;

Assembly code for this is :

movsxdl 0x238(%rbx), %rcx
xor %edx, %edx
movq 0xe8(%rbx), %rax
div %rcx
movl %edx, 0x100(%rbx)

Anyone with some suggestions, what optimizations can I try here ?

Thanks and Regards

Dipanker Singh
