Loop pipelining is an important performance optimization technique that exploits the parallelism among loop iterations. In unoptimized loops written in sequential languages like C/C++, one iteration can only begin after the previous iteration is complete. Loop pipelining allows loop iterations to overlap, which … Visa mer There are typically two factors of constraints that limit the degree of parallelism loop pipelining can exploit: one is hardware resource contention, and the other is the data … Visa mer I extracted 4 kernels in PolyBenchthat contain loop-carried dependencies. Memory accesses in PolyBench kernels are all affine … Visa mer I implemented an LLVM passto analyze the innermost loops. The problem is decomposed into two parts: estimate resource-constrained ResMII and data-dependency bounded … Visa mer WebbThe initiation interval, or II, is the number of clock cycles between the launch of successive loop iterations. The fMAX-II tradeoff Generally, striving for the lowest possible II of 1 is preferred. However, in some cases, it may be suboptimal for the scheduler to do so. For example, consider a loop with loop-carried dependencies. pakistan visa for australian citizens

Our results provide evidence that the time interval from PDS to chemotherapy influences PFS in patients with advanced EOC. The optimal time to initiate chemotherapy was between 23 and 43 days, within 3–6 weeks post-operatively. Initiating chemotherapy <23 and >43 days did not appear to benefit PFS. pakistan visiting visa application formWebb• Initiation interval (II): Number of clock cycles before the function can accept new input data. • Loop iteration latency: Number of clock cycles it takes to complete one iteration … summary of the story of mathematics

"WebbThis loop is pipelined with a loop initiation interval (II) of 1. An II of 1 means that there is a delay of 1 clock cycle between starting each successive loop iteration. The Intel® HLS Compiler attempts to pipeline loops by default, and loop pipelining is not subject to the same constant iteration count constraint that loop unrolling is. " - Initiation interval
