Performance at Scale: Clearing the Performance Bottleneck With EDA Storage

first_imgFor years, a typical EDA infrastructure has relied on the same architecture for its storage system: A scale-up storage system characterized by a single-server operating system and a controller head with shelves of disks. The architecture creates islands of storage with many disk shelves and many separate controller heads.The workflows, workloads, and infrastructure for chip design—combined with exponential data growth and the time-to-market sensitivity of the industry—constitute a clear requirement to optimize the system that stores EDA data.Using a traditional scale-up storage architecture for EDA leads to an array of problems:SCALABILITY AND PERFORMANCE BOTTLENECKSTraditional EDA storage architectures create performance bottlenecks—bottlenecks that get worse at scale. A traditional scale-up architecture requires manual data migrations among storage components to balance performance for EDA applications. The controller is the main bottleneck: Although it is typical in EDA to limit the amount of capacity per controller head to make sure that performance requirements are met, attaching too much capacity to the controller can saturate it—a situation made worse by the fact that adding capacity does not scale performance.Performance bottlenecks levied by the storage system can reduce wall-clock performance (turn-around time) for suites of concurrent jobs, which can affect the time it takes to bring a chip to market and, ultimately, revenue. UNWANTED ISLANDS OF STORAGETo avoid saturation of a control head, engineers using typical scale-up storage are forced to create “islands of storage” – isolated storage clusters each with their own volume and namespace. Scale-up storage architectures can also add limitations to storage growth – such as requiring that newer technologies, such as all-flash performance storage, be installed on a separate volume. These limitations can create challenges for engineering since projects can be forced to span multiple volumes, and scripts may have to be modified to accommodate path changes. This also creates additional overhead for storage management.INEFFICIENT UTILIZATION OF DISK SPACECapacity is unevenly utilized across islands of storage: Some volumes are underutilized while others are oversubscribed. The result is many volumes, all with pockets of free space. The uneven utilization forces you to manually rebalance volumes across aggregates and to manually migrate data to an even level. The burden of managing data across volumes and migrating data to distribute it evenly not only undermines performance but also increases operational expenses. From the engineering perspective, there is increased risk that a last minute request for space, while technically available in aggregate, may not be available within a single volume.MULTIPLE POINTS OF MANAGEMENTWith no central point of management, each filer must be individually managed. The management overhead increases the total cost of ownership (TCO) along with OpEx. The multiple points of manual management also put EDA companies at a strategic disadvantage because the lack of centralized management undermines a business unit’s ability to expand storage to adapt to demand, which can in turn hamper efforts to reduce time-to-market.With file server sprawl, the cost of managing fast-growing data can also exceed the IT budget by resulting in costly data migrations to eliminate hot spots. Similarly, backup and replication becomes increasingly complex and costly.STORAGE UNCERTAINTYExpanding data sets coupled with dynamic business models can make storage requirements difficult to forecast. Up-front purchasing decisions, based on business and data forecasts, can misestimate storage capacity. Forecasting capacity in advance of actual known needs undermines adaptability to changing business needs. With scale-up architectures, simply adding capacity causes a disruption – as does manually load-balancing control heads. Downtime increases project costs, directly causes delays in time-to-market and ultimately reduces profit margins.Such a model of early storage provisioning can also lead to vendor lock-in and a loss of negotiation leverage that further increases costs.PERFORMANCE (I/O) HOTSPOTSHistorically, CPU performance and quantity of cores was the primary bottleneck to EDA tools. When more performance was needed, semiconductor companies typically responded by adding cores. Today, however, we have faster networks and commodity servers available – with some compute grids growing to 50,000 cores and beyond. Even with as few as 1000 cores, however, the bottleneck shifts from compute to storage. EDA workflows tend to store large numbers of files in a deep and wide directory structure, which compounds the challenge around traditional storage infrastructures. For projects sharing the same controller or export, metadata-intensive workloads can saturate the controller CPU causing latency to spike and users are no longer able to interact with the storage system. For example, if an engineer kicks off 500 simulation jobs against /project/chip1_verif directory, anyone else interactively working in that space will notice delays in response.Today’s compute grid is dense and extensive, leaving storage as the bottleneck. For many semiconductor companies, the storage system still has a legacy dual controller head architecture, such as a traditional scale-up NAS system, leaving EDA tools vulnerable to I/O hotspots.Isilon Solutions for EDA WorkloadsIsilon overcomes the problems that undermine traditional NAS systems by combining the three traditional layers of storage architecture—file system, volume manager, and data protection—into a scale-out NAS cluster with a distributed file system.Such a scale-out architecture increases performance for concurrent jobs, improves disk utilization and storage efficiency to lower capital expenditures (CapEx), centralizes management to reduce operating expenses, and delivers strategic advantages to adapt to changing storage requirements and improve time-to-market.For more information about Dell EMC Isilon NAS and how we are delivering performance, scalability and efficiency to optimize data storage for EDA, please read our latest white paper here.last_img read more

Junior D’Tigers to Arrive Nigeria on Wednesday

first_imgPresident of the Nigeria Basketball Federation, Musa Kida, through the team’s NBBF representative, Suraj Yusuf, revealed his admiration for the boys after their feat coming third against all odds.National Coordinator of the Nestlé Milo Basketball Championship, Sam Ahmedu, one of the delegation to Cape Verde has also redeemed his pledge to the team after their victory against Guinea in the third place match.The team started the game brightly shaking off Saturdays semifinal defeat to Mali taking the game 20-10 in the first quarter but the momentum watered down in the second as they could only get three points as the Guineans fought back to take the second quarter 13-3 to end the first half tied 23-23 points.The third quarter ended in favour of the Guineans 14-11 but a spirited comeback in the final quarter of the game from the Nigerians saw them take the game 20-16 to win the game by one point 54-53.Speaking after the game Head Coach of the team Fubara Onyanabo said he is excited about the outcome of the game and seeing the boys take the third position remains a consolation which they can build on in the future.“I am really excited, it was a very tensed game and I could not take my eyes off the board in the final quarter of the game because the Guineans kept coming at us but the boys held their nerves for the win.“I am disappointed we didn’t get the World Cup ticket, we tried our best and I am sure we will do better next time. It goes to show that with proper preparation, Nigeria can do better at these competitions. We have abundance of talents in this country I must say that for certain.”Nigeria has matched their best performance at the tournament. The country finished third at the maiden edition of the competition in 2009.In the final match, Egypt dethroned defending champions Mali to win their fourth title of the U16 championship and will head into the 2020 U17 FIBA World Cup in Sofia, Bulgaria as Africa champions.Share this:FacebookRedditTwitterPrintPinterestEmailWhatsAppSkypeLinkedInTumblrPocketTelegram Nigeria’s bronze winning contingent to the recently concluded FIBA U-16 Africa Basketball Championship in Cape Verde will arrive the Murtala International Airport by 11:40am Nigeria time on Wednesday.The team departed Praia, the capital city of Cape Verde 22:00 (12am Nigerian time) yesterday to arrive in Senegal where plans have been concluded for the team to take a tour of the prestigious NBA and Aspire Academies in Dakar before departing Senegal for Nairobi.The team finished third on the log at the recently concluded FIBA U16 African Basketball championship in Cape Verde beating Guinea 54-53 in the losers final on Sunday.last_img read more

Markey happy to see Bell excel

first_imgWhile Bell excelled in the running game, quarterback Ben Olson was able to pick apart Stanford’s secondary. Five receivers, two tight ends and Bell and Markey all caught passes, which was much different from how UCLA’s passing game operated last season, when Markey’s 35 catches were tops on the team. In nine of 13 games last season, four receivers or less caught passes. “I would love to catch balls out of the backfield,” Markey said, “but it was really nice to see our receivers play as well as they did, and Ben hit them with the ball as well as he did. If they play like that all the time, I would not mind not catching any balls.” Making amends UCLA’s heralded defense allowed 17 points and 383 yards in the win at Stanford, which was shut out and totaled 166 yards in a loss at the Rose Bowl last season. That was a big reason UCLA’s defense seemed a bit more intense in Tuesday’s practice. “They’re a little ornery, and I like that,” UCLA coach Karl Dorrell said. “There’s a standard we’re expecting to play, and overall they played well, but they understood the issues that rose up and bit us a little bit.” Position change Bruins redshirt freshman Darius Savage was switched from defensive tackle to offensive line. He spent much of the practice working with the offensive line, although he did spend some time on the scout team, and stayed after practice to work on his technique. “He’s on our PAT protection already, and it seems like he’s more natural on the offensive side than the defensive side,” Dorrell said. “He just wants to play. “He thinks this will probably be a little faster chance for him to play, given that he’s behind the defense.” Savage, an accomplished shot put and discus thrower, missed spring ball to participate in track and field. He played offensive line at Morse High in San Diego. Injury update Bruins starting cornerback Rodney Van did not practice because of a sprained left ankle, but Dorrell said he anticipated Van participating today. Van was the only injury UCLA suffered in the season opener, but backup defensive tackle Jerzy Siewierski was slowed in practice by pain in his arch. That injury is not thought to be significant. Odds and ends UCLA, which is ranked 13th, moved up one spot in the Associated Press poll. The Bruins jumped three spots, to 14th, in the USA Today coaches poll. … Former UCLA offensive line coach Mark Weber, who spent six years on Bob Toledo’s staff and was fired after one season with Dorrell, is in his first year as BYU’s offensive line coach. … BYU quarterback Max Hall, a transfer from Arizona State, is the nephew of former Dallas Cowboys quarterback Danny White. … Olson was named the Pacific-10 Conference Offensive Player of the Week. He completed 16 of 29 passes for 286 yards and a career-high five touchdowns. [email protected] local news?Sign up for the Localist and stay informed Something went wrong. Please try again.subscribeCongratulations! You’re all set! And Markey, a senior starting tailback, isn’t about to gripe about being overshadowed by backfield ‘mate Kahlil Bell, or by a receiving corps that hauled in five touchdowns. “We watched film, and I got an A grading out,” Markey said. “The big plays weren’t there for me, and how I play, I tell myself to be patient and let the game come to you. I feel that’s what I did.” Markey carried 20 times for a workmanlike 71 yards. There were a few instances where Markey was a slipped tackle or quick cut from breaking off a long run, but he isn’t concerned. Instead, Markey, who ran for 1,107 yards last season, said he was thrilled Bell had a career-best 195 yards on 19 carries. “One of my goals is to have one of the best backfields in the nation, and that’s what I told (Bell) before the game,” Markey said. “If one of us is not clicking, the other will be clicking, and he was clicking Saturday. He played a great game.” By Brian Dohn STAFF WRITER Chris Markey led UCLA in rushing last season, but was a mere 124 yards behind the Bruins’ leading ground gainer in the season opening win at Stanford. He was UCLA’s leading receiver in 2006, but had one catch for 2 yards against the Cardinal. last_img read more
